Aluminium U Channel

https://www.otalum.com/products/aluminium-u-channel/

In Otalum, the aluminium U channel also known as u shaped aluminium channel and u shaped aluminium profile, comes in both equal and unequal dimensions, and it can also be cut to a specific size if the existing aluminium U sections do not meet your requirements.

 As a professional aluminium profile company in China, Otalum mainly produces our U-shaped aluminium channels/profiles according to the standard GB5237.1-2017. In terms of the raw materials, Otalum's extruded aluminium U profile channel mainly uses alloys including 6005, 6060, 6061, 6063, 6082, etc.

 Precise cutting to length and processing services are also available with the fastest lead time in the current industry.

 Types of Otalum Aluminium U Channel

l Aluminium Equal Channel

U-channels have equal length of bottom and legs.

l Aluminium Unequal Channel

U-channels have equal length of legs but unequal length of bottom.

 What are the applications of aluminium U channel?

Aluminum U channels also known as u shaped aluminium channels and u shaped aluminium profiles, offer a large range of applications across many industries. The most common uses include framing, tracks, slides, protective edges, railings, rails, rims, and decoration, to name just a few.

 Characteristics of Aluminum Channels

1. High electrical and thermal conductivity.

By weight, aluminum is twice as conductive as copper, making it the most commonly used material for large-capacity overhead power lines. Light intensity. Aluminum has a high strength-to-weight ratio, making it the best solution to the challenge of lightweight load-bearing.

 2. Heat transfer and shielding.

Where weight and stiffness are the main considerations (aerospace applications), aluminum has better heat transfer and shielding performance than copper shielding.

 3. Corrosion and rust resistance.

When exposed to the air, aluminum will form an oxide coating to prevent rust and corrosion. If necessary, the coating can be enhanced by anodizing.

 4. Non-magnetic

In applications where the magnetic properties of the material cause problems, the non-magnetic properties of aluminum are particularly valuable.

 5. There is no spark

Because it does not generate sparks, aluminum is usually the best solution for highly flammable or explosive applications.

 6. 100% recyclable

In the recycling process, aluminum is equivalent to the original material and is not degraded. In addition, aluminum recycling only requires 5% of the energy input required to process the original material.

 7. Low toxicity and high reflectivity are other characteristics that make aluminum channels the material of choice. Users with apps that benefit from these features will look for the best solution for aluminum channels.

 What is Aluminum U Channel and What is It Used For?

Aluminum channels are also commonly called C-channels or U-channels-depending on how you hold it, they are usually used for general manufacturing, light construction works, decoration, shop decoration, vehicle manufacturing, and shipbuilding.

 They are easy to manufacture because aluminum can be easily cut with a power tool or hacksaw; you can also drill and process it very easily.

 The correct tools and equipment can be used for welding. Although it requires more skills than welding mild steel, why not try it-we provide a full range of aluminum electrodes, machines and consumables.

 Pure aluminum is relatively soft, but it is usually alloyed with other metals to improve its mechanical properties. It is a durable, light-weight metal, non-ferromagnetic and difficult to ignite, has good corrosion resistance and excellent strength-to-weight ratio.

 The product has a rolling finish, which is the finish and surface state of aluminum immediately after extrusion. Different batches, manufacturers, and even products produced in the same batch have very different finishes and surface visual characteristics.

Aluminium Heatsink Profile

https://www.otalum.com/products/aluminium-heatsink-profile.html

Otalum stocks a wide range of extruded aluminium heat sinks and provide aluminium extrusion heat sink profiles to custom designs, available in a range of finishes. If the existing products are not suitable for your needs, our technical team can help you to design your products and realize them.

 All extrusions can be supplied as cut, drilled, or machined to customer specifications. As a professional extruded aluminum heatsink manufacturer, Otalum operates the latest CNC drilling and machining centres which provide accurately machined, cost-efficient parts on short cycle-times.

 What is a heat sink?

A heat sink is a component that increases the heat flow away from a hot device. It accomplishes this task by increasing the device's working surface area and the amount of low-temperature fluid that moves across its enlarged surface area.  

 Why Aluminium Heat sink?

An aluminum heat sink profile is the most widely used product for thermal solutions. Following are some reasons why it is so popular.

 Characteristics Of Heat Sink

l Good thermal and electrical conductivity

l Low density (about 2.7kg/m³)

l Low weight

l High strength

l Easy malleability

l Easy machining

l Excellent corrosion resistance

l non-magnetic which avoids interference of magnetic fields

l Easy to recycle

 Aluminium VS Copper Heat Sink

1.Thermal Conductivity

Copper is more conductive than aluminum. In fact, aluminum only has 60% of the thermal conductivity of copper.

 2.Weight

Aluminum accounts for only 30% of the density of copper. This means that the weight can be greatly reduced.

 3.Cost

Aluminum is much cheaper than copper. In fact, its cost is about one-third. This can save a lot of cost.

 How a Heat Sink Works

The heat sink must protect the electronic equipment and components from overheating. Therefore, they must be made of certain materials with good thermal conductivity.

Most devices that use power electronic equipment require a temperature-controlled environment. Otherwise, they are in danger of overheating, which may affect performance or, more seriously, become a safety hazard.

Essentially, a heat sink profile is a way to dissipate any heat generated from a device or component. This requires an optimal speed to dissipate heat from the source at the same rate as the rate at which the source generates heat.

In fact, optimization is the key to the success of any radiator system. This affects the choice of materials and basic aspects such as complexity, size, quality, and cost.

Therefore, while the selection of materials is crucial, other factors also need to be considered.

 Where are Extruded Heat Sinks Used For?

Commercial LED lighting

The extruded heat sink provides effective cooling for the LED (Light Emitting Diode) light source. These radiators are very small and can be mass produced.

 Circuit board & PCB (PC board)

By providing a precise combination of vertical and horizontal cooling, aluminum heat sink extrusions provide an effective thermal management process for circuit boards and PCBs. Various thicknesses and customized forms are also easy to achieve.

 Electronic instrument or electronic equipment:

The radiator is an indispensable device for electrical appliances, which can effectively dissipate the heat of the output transistor.

 Automotive equipment, NEV (New Energy Vehicle)

The radiators used in automotive electronic equipment enable high-density components to operate at stable temperatures under a wide range of environmental conditions.

 The purpose of the heat sink is specifically designed to extract heat from the components in the electronic device. The radiator is generally polished, and in most cases, it can be anodized or powder coated to improve surface protection and corrosion resistance.

All components such as walls, columns, floors, beams, stairways and balconies as well as openings for windows and doors can be constructed with this system. With the correct use of our aluminium shuttering construction system, one can not only greatly increase the efficiency of his/her work, but he/she can also produce an extraordinarily strong structure with an excellent concrete finish.

 Compared with traditional formwork, aluminium formwork can be recycled as industrial aluminium profiles. With an average weight of 23 - 27 kg/m2, aluminium formwork is easy to install, and it can also save the cost of manpower and increase efficiency. Meanwhile, the concrete made by aluminium formwork system has a much better finish than that by the traditional systems, thus greatly improving the project quality.

 As a professional aluminium formwork supplier, Otalum has more than 10 years' experience in producing aluminium formwork profiles. Our 5000-ton extrusion press can produce as large as 450mm width aluminium formwork panels, which is sufficient in most cases. All the formwork products are capable of the customed finishing and fabrication service.

 Benefits of Aluminium Curtain Wall Profile

1.Aluminum curtain wall profile has good rigidity, light weight and high strength.  Aluminum veneer curtain wall panels have good corrosion resistance, and the fluorocarbon paint can last for 25 years.

 2.The aluminum curtain wall profile has good workmanship. The aluminum plate can be processed into a variety of complex geometric shapes such as plane, arc and spherical surface by adopting the process of processing first and then spraying paint.  

 3.The aluminum curtain wall profile is not easy to be stained and is easy to clean and maintain. The non-adhesiveness of the fluorine coating film makes it difficult for contaminants to adhere to the surface, and it has good cleanliness.  

 4.The installation and construction of aluminum curtain wall is convenient and quick. The aluminum plate is formed in the factory, and the construction site does not need to be cut and simply fixed.

 5.The aluminum curtain wall profile can be recycled and reused, which is beneficial to environmental protection. Aluminum plate can be 100% recycled, with higher recycling value.

 Aluminium Curtain Wall Profile Application

The most important characteristics of Curtin Wall Profile in production are heat insulation, moisture resistance, and sound insulation, which can optimize the ambient temperature and light, thereby reducing the building's demand for electricity.

 On the other hand, the curtain wall, because it is a very light structure, reduces the overall load of the building, and is also very resistant to earthquakes. It is ultimately superior to other exterior walls in terms of installation, aesthetics and affordability.

 The aluminum curtain wall is actually the chassis and lamps placed around the project. The glass used as the facade of the building is installed on the curtain wall structure, not on the building itself, so the weight shrinks in the building. This weight reduction increases the earthquake resistance of the building.

 High-strength, light-weight and beautiful curtain walls are widely used as curtain wall panels and substitute solid wall structures. The curtain wall can be used as the outer wall, skylight and canopy of large-span buildings such as hospitals, office buildings, stadiums, airports, railway stations, exhibition centers, etc.

 Aluminium Extrusion Profiles in Architecture and Construction

Due to its structure and cost advantages, aluminum extrusion profiles have become the basic materials as architectural aluminum extrusion profiles. Since aluminum extrusion profile can form complex shapes on continuous long films, it can be used for various building materials. The applications of aluminum extrusion profiles range from railings and railings to building exterior walls and bleaching agents. The strong and lightweight aluminum profile is very suitable for applications such as canopies, because the structure of such applications is not bulky, but must be able to withstand the load. (High stiffness means you need less stiffness, which means more weight can be reduced.) It is also used for suspended ceilings and walls.

 Why Choose Extruded Aluminium Construction Profiles

The extruded aluminum used in construction is strong, light, durable and highly corrosion resistant. Compared with alternative frame materials such as wood, aluminum profiles do not require regular painting or dyeing to maintain their weather resistance. Aluminum hydroxide can be specified in a variety of finishes and treatment methods, so that it has extremely high thermal efficiency, ideal performance, and almost no maintenance in almost any environment.

 FAQ of Aluminium Construction Profiles

Q1

Can you briefly explain the process of aluminium extrusion?

Aluminium extrusion is a metal forming process used to transform lengths of aluminium alloy into objects with a particular cross-section. The aluminium lengths, called billets, are pushed through an extrusion die with a smaller cross-sectional area than the billets themselves. The billets take on the shape of the cross-section on the die, so they can be used in various applications. The aluminium extrusion process is a relatively quick, simple and cost-effective one, and aluminium is particularly suited to this kind of form.

 Q2

Which aluminium alloy do you typically use in the extrusion process?

It depends on the nature of your project. Wherever possible, we use 6000 series aluminium extrusion alloys, as they are widely available and suited for commercial use. Of the available aluminium extrusion grades, we primarily use:

6063

6061

6005

6082

There are other available aluminium extrusion grades, however, there would rarely be a case in which we would need to use these. If you are unsure of whether the available aluminium extrusion grades are suited to your intended application, or would like to know which grade we would recommend, please feel free to contact us.

 Q3

What are thermal break extruded aluminium profiles?

Aluminium is cost-effective, lightweight and easy to work with. However, it's also very good at conducting heat, which isn't ideal when it's used for things like windows and doors. It offers poor insulation in winter and little protection from heat in summer.

Thermal break extruded aluminium profiles solve this problem. A thermal break profile is effectively an aluminium sandwich and contains non-conductive material that acts as a thermal 'break' or barrier. These profiles can conduct up to 1,000 times less heat than aluminium alone.

 Q4

What standard for solid, hollow and semi-hollow aluminium building profiles?

Solid refers to a shape with no cavities at all, like flat bars or rods. Semi-hollow is a shape that is partially enclosed but always keep a gap open, even very small. Hollow shapes contain one or more totally closed areas like a tube.

 Q5

How much does aluminium extrusion cost per kg?

How much aluminium extrusion costs per kilo is governed by the London Metal Exchange (LME) or another local aluminium price, taking into account the global market and fluctuations in supply and demand. What this means is that the cost per kilo of aluminium extrusion is never the same. In addition, aluminium is traded in US dollars, which means that we have to take the exchange rate into account.

In order to protect our customers from price fluctuations, we offer prices that are fixed for 7 to 15 days after a quote is first produced. So if the cost per kg of aluminium extrusion increases a day after we’ve quoted you, we'll absorb that cost.

If you wish to secure a fixed cost per kg for a period of up to 12 months, we can arrange to forward purchase metal as a means of securing this price. Having a fixed aluminium extrusion cost per kg for a year can give you a valuable period of price security that proves particularly helpful in the early days of your business, or in lean times. It also makes good business sense!



Q6

What is the advantage of aluminium alloy?

Aluminum alloy is soft and usually alloyed with copper, zinc, magnesium, silicon, manganese and lithium to increase strength. When aluminum alloy is exposed to air, an anti-oxidant coating will be formed instantly to protect products. Aluminum alloy is one of the lightest metals. The application of products ranges from precision technology to daily commodities.

 Aluminium Extrusion Uses

Aluminium extrusion transforms aluminum alloy into a variety of products suitable for consumers and industrial markets. Aluminum profiles have many uses in electronics, automobiles, public transportation, bridge deck paving, telecommunications, solar energy, renewable energy and other industries.

 The extrusion process makes full use of the excellent ductility of aluminum. The aluminum alloy billet is heated to soften it, and then pressed into a special steel mold with a hydraulic press or a punch under high pressure to form a shape. The result is an aluminum sheet that maintains the specific shape of the mold.

 Aluminum Extrusion Alloys

Different alloys in different states can make extruded aluminum profiles to meet the various needs-from household items to space vehicles. Basically, aluminum profiles can be extruded from any deformable aluminum alloy (even casting) in one way or another. However, metals need special flow characteristics to flow through the holes and cavities of the matrix under high temperature compression. Therefore, metals should: fill all the holes at the exit of the matrix at the same high speed, provide the required micro-structure, reach the predetermined strength and other characteristics and shape the best surface quality.

 Therefore, special aluminum alloys specifically for pressing (extrusion) are being developed. In this way, the chemical composition of these alloys is optimized to make them most suitable for the conditions of the pressing process and to ensure the required quality of the molded products.
