What are ferrous and non-ferrous metals?
Metals can be divided in various ways. It can be given to the properties of the metal and its applicability. In practice, the division between ferrous and non-ferrous metals is common. This division is based on whether or not present in the ingredient iron.
Iron is an element from the chemistry. In Latin is called iron ferrum. Of this, the word derived ferrous. Ferro is in chemistry marked with the symbol Fe which represents the first two letters of Ferrum. Iron is a gray-colored metal having an atomic number of 26. It is widely used in the mechanical engineering but also in other technical fields. Usually iron is alloyed with other elements such as carbon (C). When iron 0.1 to 1.7 percent carbon is added is referred to as steel. Metal covered by Ferro are magnetic and contain at least 50 percent iron.
Nonferrous metals contain iron. When non-ferrous metals to be alloyed, the percentage of iron which is added should not be higher than 50 percent in order to let the alloy include among nonferrous. The metal covered nonferrous are diverse. A number of examples of non-ferrous metals are copper, zinc, chromium, gold, silver, tin, aluminum and titanium. Because so many nonferrous metals under attack is often a subdivision. The division between pure metals and nonferrous metal alloys usual.
Among pure metals include the following categories:
Precious metals: these metals are hardly affected by oxidation. Examples are gold and platinum. Silver is also among precious metals though it is somewhat more susceptible to oxidation.
Heavy metals have a high atomic mass and heavier than iron. Examples of these are: mercury, lead and cadmium.
Light metals: These are metals that are lighter than iron as aluminum.
Among non-ferrous metal alloys, these categories are:
Die-cast alloys, such as bronze.
Wrought alloys are alloys that have arisen through a forging.
Within the engineering uses of ferrous and non-ferrous metals. The properties of metals vary widely. By means of alloys can be combined, the properties of metals. Alloys are widely used in practice.
