Material CuZn36Pb3, mat. No. CW603N, is an unhardenable wrought alloy. to the comparable make CuZn36Pb3, mat. No. 2.0375 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: limited machinability: very good hard soldering: moderately soft soldering: very good TIG-welding: unfavorable burnishing: very good Application: for thin-walled extruded profiles e.g. construction profiles, hand rails, for stair rails, for screw machine parts in watch and electrical industry as well as for precision mechanics and optics.
