Nickel Aluminum Bronze C95500

Similar to other grades of aluminum bronze, C95500 contains nickel. Nickel makes C95500 aluminum bronze one of the toughest non-ferrous alloys known. The alloy exhibits exceptional yield, compressive strength, high hardness, and fairly high elongation. It is an excellent bearing material suitable for heavy duty, high shock, and high impact applications. The alloy has good resistance to sea water corrosion, heat resistance, good machinability, and weldability.
