Description

CuZn0,5, mat. No CW119C, is counted among unhardenable, low alloyed copper alloys. To the comparable make CuZn0,5, mat. No 2.0205, acc. to DIN 17666 : 1983-12 applies: A strength increase is achievable only by cold forming. According to the deformation level the tensile strength is between 220 and 360 N/mm². Temperature for removal of workhardening is above 250°C. Electrical conductivity is very high. Corrosion resistance is equal to unalloyed copper. Processing properties: hot forming: good cold forming: very good machinability: moderately soft and hard soldering: very good gas shielded welding: very good burnishing: good Application: For strips, construction parts and all types of hollow-ware as well as for heat transmission elements. 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)
