Aluminiumbronze

Aluminumbronze is characterized by high mechanical values, even at low and higher temperatures. Excellent corrosion and seawater resistance and very durable. Suitable for applications in aggressive environments.

We have an extensive stock program in Aluminiumbronze with round, square, rectangle and hexagonal bars in addition to many sizes in tubes. The most common alloys are: CuAl10Fe5Ni5 (CC333G), CuAl10Ni5Fe4 (CW307G) and CuAl10Fe2-C (CC331G) comparable to Concast 954.

Due to the lack of lead and zinc, bearings in aluminumbronze must be lubricated.

There are three common production methods for aluminumbronze: continuous cast, extruded/drawn and centrifugally cast. Extruded and drawn material is produced in small dimensions up to approx. Ø52 mm with an h11 tolerance. This is especially ideal for CNC processing.

Typical applications of the aluminum bronze are highly loaded bearings, guideway profiles, spindle nuts, gears.
