CuNi2Be, mat. No CW110C, is counted among hardenable, low alloyed copper alloys. To the comparable make CuNi2Be, mat. No 2.0850, acc. to DIN 17666 : 1983-12 applies: The alloy shows high tensile strength and high temperature resistance and mean electrical and favorable thermal conductivity. Processing properties: hot and cold forming: good machinability: moderately hard and soft soldering: good gas shielded welding: good burnishing: good Application: For resistance welding electrodes as well as for springs. 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)
