Material Description

Material Number Material Name Material Number (single) Standard Scope Standard Status Country Predecessor VDA 231-106 classification
CW021A (DIN EN 13601 : 2021-07) Cu-HCP CW021A DIN EN 13601 : 2021-07 Supersedes DIN EN 13601 : 2013-09 Valid Germany Cu-HCP 3.2 1)
1) Remark: Copper rod, bar and wire for general electrical purposes. Deoxidised coppers of this type are produced with the addition of a controlled amount of deoxidiser, preferably phosphorus, and contain a controlled low amount of residual deoxidiser; these coppers have high electrical conductivity. These coppers may be heat-treated, welded or brazed without the need for special precautions to avoid hydrogen embrittlement.
