CC761S (DIN EN 1982 : 1998-12) CuZn16Si4-C CC761S DIN EN 1982 : 1998-12 DIN EN 1982 : 1998-12 replaced by DIN EN 1982 : 2008-08 Replaced Germany G-CuZn15Si4 CuZn16Si4-C 3.2 1)
1) Remark: CuZn16Si4-C,mat. No. CC761S (former G-CuZn15Si4, mat. No. 2.0492 acc. to DIN 1709), is a construction material with favorable corrosion and seawater resistance and very good castability (but wall-thickness sensitive) as well as high cavitation resistance. Constant high temperature strength values up to 200°C. Slightly increasing low temperature strength values up to -72°C. The material is ideal for chrome and nickel plating, sufficient bearing properties at moderate loading and lubrication. Processing properties: castability: very good machinability: conditionally soft soldering: unfavorable hard soldering: unfavorable gas fusion welding: good arc welding: unfavorable TIG-welding: good MIG-weding: conditionally resistance welding: conditionally burnishing (mech.): very good galvanizing: conditionally suitability for dip tinning: unfavorable (material specification applies for G-CuZn15Si4 acc. to DIN) Application: CuZn16Si4-C is used for high loaded, thin-walled, entangled construction parts for machine and shipbuilding, in electrical and precision engineering, for fittings and molded parts, e.g. steam fittings, valves and controlling parts for air-pressure and hydraulics with mean loadings as well as for pumps and pump blade wheels.
