Material Description

Material Number Material Name Material Number (single) Standard Scope Standard Status Country Predecessor Successor VDA 231-106 classification
CW502L (DIN EN 12166 : 2011-08) CuZn15 CW502L DIN EN 12166 : 2011-08 DIN EN 12166 : 2011-08 replaced by DIN EN 12166 : 2016-11 Replaced Germany CuZn15 CuZn15 3.2 1)
1) Remark: CuZn15 (CW502L) is an unhardenable wrought alloy. High hardness and strength parameter are achievable by cold forming only. Thermal and electrical conductivity are lower than for CuZn10. Corrosion resistance is similar to pure copper. Processing properties: warm forming: moderately cold forming: good machinability: moderately hard and soft soldering: very good TIG-welding: good burnishing: very good CuZn15 is used in electrical engineering, for metal goods as well as in jewelry industry, for metall hoses, pressure measuring instruments, signs, casings and suspension bodies. For the electrolytically tinned strip the coatings (Sn bright, Sn matt, Sn fuzed, SnPb) are listed by the application (better solderability, better corrosion resistance, reduction of the electrical contact resistance, better appearance) in the DIN EN 14436 : 2004-11 (Table 5)
