CW404J mod. | CuNi13Zn24Pb1.5

Numeric designationCW404J mod.
Chemical designationCuNi13Zn24Pb1,5
EtchingMessingätzmittel

This modified nickel silver alloy has a single-phase microstructure consisting of an α mixed crystal. The macrostructure of a cast structure is still visible in the background. The lead inclusions, which are insoluble in copper and improve the alloy’s machinability, were partially removed during etching.
