CuNi10Zn27 (CW401J)

 

All the German coppers are known for their good corrosion resistance and their attractive colour. The range of alloys increasingly whiten as soon as the nickel contents rises, although it is generally not interesting to exceed 18 % of nickel, except for the decoration products requiring a maximal resistance to the dirty marks and the tarnishing.
