EN 12166 CuZn36 (CW507L) – High-Strength, Unhardenable Wrought Copper Alloy
CuZn36 (CW507L) is an unhardenable wrought alloy. High hardness and strength parameter are achievable by cold forming only. Thermal and electrical conductivity are lower than for CuZn33. Corrosion resistance is similar to pure copper. Processing properties: warm forming: good cold forming: very good machinability: moderately hard soldering: good soft soldering: very good TIG-welding: moderately burnishing: very good CuZn36 is used for deep drawing components, pressure and punching components as well as for clockfaces. 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)
