Silicon Bronze Fasteners: Manufacturer, Types, Properties & Applications

Silicon bronze fasteners have become a staple in various industrial, marine, and architectural applications due to their unique blend of strength, corrosion resistance, and aesthetic appeal. Comprising copper, silicon, and other alloying elements, these fasteners provide a balance of mechanical performance and long-lasting durability even in harsh environments.

In this blog, we’ll take an in-depth look into silicon bronze fasteners, including their composition, types, properties, applications, and why Ananka Group is a trusted manufacturer and supplier of these high-performance components.

What Are Silicon Bronze Fasteners?

Silicon bronze fasteners are made from a copper-based alloy consisting of approximately 95–97% copper and 2–4% silicon, supplemented by trace elements such as manganese, iron, and zinc. Depending on the exact composition, this alloy is categorized as UNS C65100 or UNS C65500.

These fasteners offer excellent resistance to corrosion, especially in marine and chemical environments, and maintain high tensile strength along with a distinctive bronze color.

Latest from Botany Series; Bao Bab / Willow. We started this patinated bronze body last September. Since many design changes, head scratching moments, finally finished welding all the silver parts this Monday. I am celebrating with spaghetti Bolognese with red wine 🍷 Happy Friday 😆 #siliconbronze #finesilver #forgedsilver #botany #baobab #willow #tree #blackandwhite https://www.instagram.com/p/CBV5KOpJHW1/?igshid=1wuq7tbbwc97r

And here it is as one piece. Hard to make out in photos but there's a bronze flatbar edge wrapping all the way around the top... the stone top fits nicely into that detail for an inset look. The top and bottom are thru bolted as well as welded together. My engineer said it would take close to 900 lbs. to make the table tip....I jumped on the end of the cantilever and it didn't budge at all. Next post will be the patina process. collaboration with @sinceremetalworks #lokicustomfurniture #lokifurniture #castbronze #casttablebase #siliconbronze #modernfurniture #cantilever #cantileveredtable #blueonyxtop #foundry https://www.instagram.com/p/B7qhOUip9f2/?igshid=1s1eo47o5937c

Next steps involved welding the two halves of the top together on both sides and then the beginning of sanding. It made more sense to finish the top and bottom separately before welding them together since it was easier to get the surfaces dialed in that way. Just remember the bottom is actually the smaller form. The two will be one in the next post! collaboration with @sinceremetalworks #lokicustomfurniture #lokifurniture #castbronze #casttablebase #siliconbronze #abrasivesfordays #foundryfun #foundrylife #coffeetable https://www.instagram.com/p/B7n64cBJpKq/?igshid=qkw2nctydwkr
