Description

CuNi25 is comparable to CuNi25, mat. no. 2.0830, acc. to DIN 17664 : 1983-12. To the comparable DIN-mark applies: The material shows favorable specific strength values also at endurance loading and increased temperatures. Thermal conductivity of pure copper is strongly reduced by Ni, the electrical resistance strongly increases according to the Ni-content. CuNi25 is corrosion and wear resistant. warm forming: good cold forming: good machinability: moderately hard soldering: very good soft soldering: very good gas-shielded welding: very good burnishing: very good Application: Preferred alloy for coins due to its silver-white color, brilliance, tarnish resistance and favorable wear resistance. Further application as cladding material.
