Cast

Aluminum bronze is the highest strength standard copper based alloy. Concast produces C95400, C95500 and C95900 in standard sizes of rounds, tubes and rectangles. Aluminum in conjunction with iron and nickel in C95520 acts as a strengthener. All of the aluminum bronzes can be heat treated, further increasing tensile strengths.
