Concast^® aluminiumbronze

Elcas has the exclusive representation in Europe of Concast Metal Products Co., a leading American bronze foundry. Aluminumbronze Concast 954 and Concast 959 are distinguished by their extremely high load capacity and wear resistance. In addition to these properties, both alloys retain their mechanical values even at high temperatures (up to approx. 300°C). Concast 954 and Concast 959 correspond to ASTM B505 C95400 and C95900, both continuously cast alloys. Concast 954 is available in roundbar, tube and square/rectangle; Concast 959 in roundbar and rectangle. Concast 954 corresponds to CuAl10Fe2-C (CC331G) according to EN 1982.

Besides Concast 954 and Concast 959 we can also provide you with other extruded aluminiumbronzes like C62400 and C62900.

General applications for Concast 954 and Concast 959 are:

Mould dies
Parts for tube bending machines
Slide bearings
Heavy loaded bearings
Worms, sprockets and nuts

For enquiries whether Concast would be suitable for your application please contact us. Our technical staff can advise you in cooperation with the foundry.
