C905 Alloy Casting

alloy-casting-foundryC905 is a tin bronze alloy that’s known for its excellent corrosion resistance along with good wear resistance and strength. The C905 alloy is comprised of 86-89% copper, 1-3% zinc, and 9-11% tin. C905 is commonly used to make many parts, including bearings, bushings, pump components, valve components, gears, and steam fittings.
