C862 Alloy Casting

C862 Alloy

C862 is a manganese bronze or high-strength yellow brass alloy known for its strength. It has a higher hardness, tensile strength, and yield strength than other types of copper alloys. The metal can be used in applications where a combination of high corrosion resistance and strength is needed. C862 has been shown to have excellent resistance to many corrosive substances such as sea water, acid sludge, sulfuric acid solution, and sodium chloride aerosols.

C862 Alloy Applications
Manganese bronze is a very popular alloy widely used to make parts for the aerospace, defense, medical, and automotive industries. Marine castings, rudders, boat parts, bushings, mounts, gears, axles, valves, and bearing castings are made with manganese bronze. The zinc, manganese, and iron in these alloys make them strong and wear-resistant.

C862 Alloy Casting
Ermak’s network of foundries specialize in bronze, aluminum and zinc alloy casting. The metal alloys we use have excellent castability.

ERMAK manufactures high-quality sand castings from a variety of materials, including the C862 alloy.
