Material CuZn35Pb2, mat. No. CW601N, is an unhardenable wrought alloy. To the comparable make CuZn36Pb1,5, mat. No. 2.0331 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: very good hard soldering: moderately soft soldering: very good TIG-welding: unfavorable burnishing: very good Application: Wheels for circuit boards in watch industry, matrices for printing industry, clamps for electrical engineering, nipples, screws.
