Cobral provides various copper-zinc-nickel alloys with copper at 50-60%, zinc at 15-30% and nickel at 10-30%: CuNi12Zn24, CuNi18Zn20, CuNi18Zn27.
Centuries past since German silver alloys have come from China and today German silver strips and sheets are a concrete answer to the needs of different markets. Excellent mechanical properties, good corrosion resistance and a silver-like appearance due to the presence of nickel: these are the preconditions for choosing semi-finished German silver, which Cobral supplies in strips and sheets, cut and packed according to the specific requests of the customer.
