Aluminiumbronze CuAl11Fe6Ni6 (CW308G)

CuAl11Fe6Ni6 is the aluminium bronze in our range with the highest strength values and the best properties in terms of corrosion resistance and wear resistance. We hold round bar in this material in drawn, extruded and forged condition.

Further dimensions, including flat and square bar as well as smaller plates, are available at relatively short notice in forged and rough machined condition, also in smaller quantities. We would also draw your attention to our extensive stock range in CuAl10Ni5Fe4 (CW307G).

Selected tube dimensions are available from stock in CuAl11Fe6Ni6-C (CC334G).
