Material Description

Material Number Material Name Material Number (single) Standard Scope Standard Status Country Predecessor Successor VDA 231-106 classification
CW406J (DIN EN 12164 : 2011-08) CuNi12Zn30Pb1 CW406J DIN EN 12164 : 2011-08 DIN EN 12164 : 2011-08 replaced by DIN EN 12164 : 2016-11 Replaced Germany CuNi12Zn30Pb1 CuNi12Zn30Pb1 3.2 1)
1) Remark: Material CuNi12Zn30Pb1, mat. No. CW406J is an alloy of high strength and hardness. 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.
