Description

CuZn30 (CW505L) is an unhardenable wrought alloy. High hardness and strength parameter are achievable by cold forming only. Thermal and electrical conductivity are lower than for CuZn28. Corrosion resistance is similar to pure copper. Processing properties: warm forming: good cold forming: very good machinability: moderately hard and soft soldering: very good TIG-welding: good burnishing: very good CuZn30 is used for deep drawing components, musical instruments, hose tubes, springing elements, clockfaces and as cladding material. 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)
