EN 1652 CuZn39Pb2 H090 Brass – Properties & Applications
Material CuZn39Pb2, mat. No. CW612N, is an unhardenable wrought alloy. to the comparable make CuZn39Pb2, mat. No. 2.0380 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: very good cold forming: unfavorable machinability: very good hard soldering: moderately soft soldering: very good TIG-welding: unfavorable burnishing: very good Application: For components in precision mechanics, machine and apparatus engineering as well as for circuit boards and clockwerks for watch industry.
