Aluminum Bronze Forgings
C95400
Aluminum Bronzes are copper alloys, that contain about 5 to 12% of aluminium. In addition, Aluminum Bronzes also contain nickel, silicon, manganese, and iron. They are found in wrought and cast form. Due to the presence of hard, adherent, protective alumina film. They are stronger than that of brasses or tin bronzes and they have high corrosion resistance, and are golden in color.
