Cast C95900

Aluminum bronze is the highest strength standard copper-based alloy. Randall Bearings 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 in C959 acts as a strengthener in these alloys. All of the aluminum bronzes can be heat treated, further increasing tensile strengths.
