Silicon Bronze Sand Castings Foundry

Silicon bronze is a brass alloy with up to 96% copper. The remainder of the alloy is composed of silicon and metals, including manganese, tin, iron, or zinc. It is a low-lead alloy. The presence of silicon provides self-lubrication to the alloy. As a brass alloy, silicon bronze is highly corrosion-resistant, exhibits high strength and is easy to machine and cast. It is designated as C87850, C87610 and C87300.

Benefits of the C87850 ingot include - chemistry is tighter than ASTM B30 standards because of our casting in a continuous cast induction furnace; this eliminates dross.  Additional benefits of Eco Brass C87850 casting versus other lead-free copper alloys are:

• Lower melting temperature - Liquidus is 1616o F
• Lower Copper content than other lead-free alloys
• Fluidity- High
• Drossing – Low
• Gassing – Low

Cast parts manufactured using silicon bronze are used for high wear, high load, low abrasion parts such as ball bearings, bearing cages, raceways, spacers, gears, and valve parts. They are used for machinery, aerospace, heavy equipment, and hydraulic equipment Applications.
