✔ Standard-stocked product

Continuous cast • GreenAlloys™

Aluminum bronze is the highest strength standard copper-based alloy. Concast produces C95400, C95500, AMS 4880-C95510 and C95900 aluminum bronze alloys as Standard-stocked products in standard sizes of rounds, tubes, and rectangles. Aluminum in conjunction with iron and nickel acts as a strengthener in these alloys including C959. All of the aluminum bronzes can be heat treated, further increasing tensile strengths.
