Description

Material CuZn37Pb0,5, mat. No. CW604N, is an unhardenable wrought alloy. To the comparable make CuZn37Pb0,5, mat. No. 2.0332 acc. to DIN 17660 : 1983-12 applies: High hardness and strength parameter are achievable by cold forming only. Thermal and electrical conductivity are lower than for the unleaded brass grade of the same Zn-content. Machinability is improved by Pb-addition. Corrosion resistance to water, several saline solutions and organic liquids is also lower than for unleaded alloys of the same zinc-content. Processing properties: warm forming: good cold forming: good machinability: good hard soldering: moderately soft soldering: very good TIG-welding: moderately burnishing: very good Application: for extruded profiles of high accuracy, for circuit boards and wheels for watch industry as well as for pressure brass components.
