This table shows the BS EN material designations for the different grades of wrought copper, and their equivalent old BS material designation. The types of copper are oxygen free, tough pitch and phosphorus deoxidised, all of which may be alloyed with small amounts of silver which increases the temperature resistance.
Follow the links below for:
- Compositions, typical properties and uses of wrought and unwrought coppers
