EN 12165 Grade CuZn39Pb0.5 H080 – High‑Strength Leaded Brass Alloy

Material CuZn39Pb0,5, mat. No. CW610N, is an unhardenable wrought alloy. to the comparable make CuZn39Pb0,5, mat. No. 2.0372 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: moderately machinability: good hard soldering: moderately soft soldering: very good TIG-welding: moderately burnishing: very good Application: For plug pins, fitting parts, rivets, condenser plates, floor plate screeding and drawing instruments.
