Key Features

A copper zinc alloy with additions of manganese,iron,and aluminium, plus lead for lubricity,anti-seizing and embeddiability. Like aluminium bronzes they combine high strength with corrosion resistance.

Typical Uses

Heavy duty mill, gear wheel components and bushings, operating at high speeds under heavy loads. They require a high shaft hardness when running against steel and nonabrasive operating conditions with good lubrication.
