Material Description

Material Number Material Number (single) Standard Scope Standard Status Country Successor VDA 231-106 classification
CW704R (DIN EN 12165 : 1998-04) CW704R DIN EN 12165 : 1998-04 DIN EN 12165 : 1998-04 replaced by DIN EN 12165 : 2011-08 Replaced Germany CuZn23Al6Mn4Fe3Pb 3.2 1)
1) Remark: CuZn23Al6Mn4Fe3Pb (CW 704R former identification: CuZn23Al6Mn4Fe3) is an unhardenable copper alloy. High hardness and strength values are achievable by cold forming only. Strength properties are improved by AL- and Fe- addition. Manganese and aluminium increase corrosion resistance. The alloy is seawater resistant. Processing properties: warm forming: good cold forming: unfavorable machinability: good hard soldering: unfavorable soft soldering: unfavorable burnishing: very good CuZn23Al6Mn4Fe3Pb is a construction material of very high strength, particularly for high static loading. Application for plates and tubes in condensators and heat-exchangers as well as for seawater pipes.
