Wrought Copper Alloys—BS EN Material Designations and Old BS Equivalents

This table shows all of the wrought copper alloys available under the BS EN designation system together with a basic chemical description of the grade and the old British Standard equivalent for comparison where applicable.

The copper alloy grades are listed in numerical order based on their European designation within their respective alloy groups. This material designation can be broken down into sections (see introduction) but it ultimately defines the alloy composition range.

Most of the alloy grades listed below are specified within manufacturing standards and meet certain mechanical, physical and corrosion resistance criteria. However, note that some of the alloys listed are not currently included in any manufacturing specifications, but are included for completeness as the alloy still exists and can be specified on agreement with a manufacturer.
