CC333G / CuAl10Fe5Ni5

Aluminumbronze – Continous cast.

Aluminium bronze is well suited for heavy load applications or as an alternative when regular tin or leaded bronzes don’t meet the demands. The combination of aluminium and copper guarantees a tough material with high mechanical values. Aluminium bronze is corrosion and seawater resistant and therefore often used in the marine industry. Due to the lack of zinc and lead in this material adequate lubrication is very important.

Areas of use
Bearings for high loads, sliding parts, nut threads, marine details.

Delivery program
Solid round bar, tube, square, flat and hexagon bars
