C865 Alloy Casting

C865 Alloy

The high-strength yellow brass – copper casting alloy C865 is a casting alloy consisting mainly of copper and zinc. This alloy is primarily used for cast parts requiring strength at elevated temperatures or moderate corrosion resistance.

C865 Alloy Applications
Typical uses for this alloy include machinery parts requiring strength and toughness, lever arms, valve stems, gears, electrical hardware, boat parts, propellers for salt and fresh water, rudders, fasteners, bearings, and structural fittings for gas turbines. The automotive, builder’s hardware, electrical, industrial, and marine industries all use the high-strength yellow brass C865.
