CuZn39Pb3易切削铅黄铜合金是应用较广的铅黄铜，可切削性好，有良好的力学性能，能承受冷、热压力加工，易焊接，纤焊好，对一般腐蚀有良好的稳定性，但有腐蚀破裂倾向，主要用于空调阀门、五金机械等。
Material CuZn39Pb3, mat. No. CW614N, is an unhardenable wrought alloy. to the comparable make CuZn39Pb3, mat. No. 2.0401 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 unleaded brass 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: very good cold forming: unfavorable machinability: very good hard soldering: moderately soft soldering: very good TIG-welding: unfavorable burnishing: very good Application: Main alloy of the brass materials for machining on automats. Use for all types of form turning parts, in precision engineering as well as in watch and electrical industry.
