EN 1652 Grade CuZn10 H110 – High-Performance Copper Alloy for Electrical and Jewelry Applications
CuZn10 (CW501L) is an unhardenable wrought alloy. High hardness and strength parameter are achievable by cold forming only. Thermal conductivity is lower than for CuZn5. Favorable electrical conductivity. Corrosion resistance is similar to pure copper. Processing properties: warm forming: moderately cold forming: good machinability: unfavorable hard and soft soldering: very good TIG-welding: good burnishing: good CuZn10 is used in electrical engineering, for metal goods as well as in jewelry and watches industry, for projectile casings and as cladding and enamelling 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)
