Description

Material CuNi12Zn30Pb1, mat. No. CW406J is an alloy of high strength and hardness. To the comparabel mark CuNi12Zn30Pb1, mat. No. 2.0780, acc. to DIN 17663 : 1983-12 applies: Strength is further increasable due to the high strain hardening capability. The material does not embrittle at low temperatures. Low electrical and thermal conductivity. The alloy is non-magnetic, corrosion resistance is better than for pure copper. Machinability improves by Pb-addition, ductility decreases and cold workabiliy deteriorates. Processing properties: warm forming: unfavorable cold forming: moderately machinability: good hard and soft soldering: very good TIG-welding: moderately burnishing: good Application: Particularly in precision engineering and in toolbuilding for turning and drilling parts, in electrical engineering and electronics as well as in shipbuilding and in construction trade.
