CW111C (DIN EN 12163 : 2011-08)	CW111C	DIN EN 12163 : 2011-08	DIN EN 12163 : 2011-08 replaced by DIN EN 12163 : 2016-11	Replaced	Germany	CuNi2Si	CuNi2Si	CuNi2Si, mat. No CW111C, is counted among hardenable, low alloyed copper alloys. To the comparable make CuBNi2Si, mat. No 2.0855, acc. to DIN 17666 : 1983-12 applies: The material shows favorable electrical and thermal conductivity, corrosion resistance, high fatigue and creep resistance as well as favorable spring properties. CuNi2Si is in hardened condition resistant to stress corrosion. Temperature for removal of workhardening approximates 450°C. Strength still increases at low-temperature range. Processing properties: hot and cold forming: good machinability: moderately soft soldering: good hard soldering: moderately gas shielded welding: moderately burnishing: good Application: Particularly for aerial line material, such as clamps, mounting links, nuts, high-strength and corrosion resistant screws. Furthermore for wire ropes in electrical overhead line construction, bearing bushings, roller bearing cages, valve guide bushings and 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)
