C86300 Manganese Bronze / C863 Manganese Bronze

SAE 430B bronze can operate at low speeds under heavy loads, but require high shaft hardness and nonabrasive operating conditions. This alloy has excellent mechanical qualities and good corrosion resistance. This alloy is compromised of copper, manganese, aluminum and iron. This combination raises the tensile strength.
