EN 12164 CuZn35Pb1 R400 Brass – High Strength & Cold Formability
Material CuZn35Pb1, mat. No. CW600N, is an unhardenable wrought alloy. 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: For wheels and circuit boards in watch industry, matrices for printing industry, clamps for electrical engineering, nipples, screws.
