CuZn5 R350 – EN 12163 Grade Wrought Alloy for Electrical & Industrial Applications
CuZn5 (CW500L) is an unhardenable wrought alloy. High hardness and strength parameter are achievable by cold forming only. CuZn5 has a favorable conductivity, resistance to atmospheric corrosion and is ideal for enamelling. Processing properties: warm forming: moderately cold forming: good machinability: unfavorable hard and soft soldering: very good TIG-welding: good burnishing: good The material is used for installation components in electrical engineering, for shock-absorber rods, metal goods as well as in jewelry and watches industry. 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)
