Material Description

Material Number Material Name Material Number (single) Standard Scope Standard Status Country Predecessor Successor VDA 231-106 classification
CC492K (DIN EN 1982 : 1998-12) CuSn7Zn2Pb3-C CC492K DIN EN 1982 : 1998-12 DIN EN 1982 : 1998-12 replaced by DIN EN 1982 : 2008-08 Replaced Germany G-CuSn6ZnNi CuSn7Zn2Pb3-C 3.2 1)
1) Remark: CuSn7Zn2Pb3-C, mat. No. CC492K (former G-CuSn6ZnNi, mat. No. 2.1093 ac. to DIN 1705), is a construction material with favorable strength and elongation. It is seawater resistant and good castable. The casting material is applicated for fittings and pump casings as well as for castings with requirements to pressure tightness. It shows nearly the same strength values as G-CuSn10Zn (mat. No. 2.1086 acc. to DIN 1705) Processing properties: machinability: good soft soldering: good hard soldering: good gas fusion welding: conditionally gas shielded welding: bad burnishing (mech.): good galvanizing: good suitability for dip tinning: good (material specification applies for G-CuSn6ZnNi acc. to DIN)
