Silicon Bronze Fasteners Introduction Silicon bronze is a corrosion-resistant alloy primarily composed of copper, silicon, and a small amount of other elements such as zinc, manganese, or iron. Silicon bronze fasteners are known for their excellent corrosion resistance, non-magnetic properties, and attractive golden-bronze appearance. These fasteners are widely used in marine environments, architectural applications, and chemical processing industries due to their strength and durability. Uses Silicon bronze fasteners are used in applications where resistance to corrosion, especially from saltwater, acids, and chemicals, is critical. Common uses include: Marine industry: Boat building, docks, and piers Architecture: Decorative and structural elements exposed to weather Electrical and plumbing systems: Due to excellent conductivity and corrosion resistance Chemical processing plants: Where exposure to harsh substances is frequent Woodworking: Especially with pressure-treated lumber Aerospace and defense: Where non-sparking and non-magnetic fasteners are required Chemical Composition Silicon bronze fasteners are often made from UNS C65500 or C65100, and have the following typical chemical composition: Element Composition (%) Copper (Cu) 94.0 – 96.0 Silicon (Si) 2.8 – 3.8 Manganese (Mn) Up to 1.5 Zinc (Zn) Up to 1.5 Iron (Fe) Up to 0.8 Other Elements Trace amounts Silicon improves strength and corrosion resistance, while maintaining good ductility. Sizes and Length Silicon bronze fasteners are available in a variety of standard and custom sizes based on application: Bolts and Screws: Diameter: M2 to M24 or #4 to 1 inch Length: 5 mm to 200 mm, or longer for custom applications Nuts: Compatible with corresponding bolt sizes Washers: Inner Diameter: 3 mm to 30 mm Thickness: 0.5 mm to 5 mm Rivets and Studs: Various lengths and diameters available Standards followed may include ASTM, ANSI, DIN, ISO, or BS depending on the requirement.
