Aluminiumbronze CuAl10Fe3Mn2 (CW306G)

This material is a copper aluminium alloy with additions of iron and manganese, but without nickel. CuAl10Fe3Mn2 shows the typical properties of the aluminium bronzes: high strength values, including at elevated temperatures, wear resistance, good corrosion resistance and good resistance to scaling, erosion and cavitation. 

We stock round bar in extruded condition. For other forms, or where higher demands are placed on strength and other properties, we recommend comparing this material with CuAl10Ni5Fe4 and CuAl11Fe6Ni6.
