Copper and Copper Alloy Ingots and Castings (BS EN 1982)—Compositions, Properties, Processes and Uses

Copper and copper alloy ingots and castings are specified according to BS EN 1982. Compositions, mechanical properties, applicable casting processes and characteristics and uses are given in these tables below, for castings. The EN designations for castings begin ‘CC’ and the EN symbols end in ‘-C’. For ingots, the EN designations begin ‘CB’ and the EN symbols end in ‘-B’.

The first table shows compositions of copper alloy castings, with range or maximum for each element. Note that not all elements listed as impurities are shown here. For the full chemical composition you should refer to the standard or the Copper and copper alloys. Compendium of compositions and products PD CEN/TS 13388. The second gives typical minimum mechanical properties and applicable casting processes.

Where alloys are approved for drinking water contact (see full list of 4MS copper and copper alloy materials), this is indicated in the characteristics and uses column.

Note there might be slight variations between compositions of castings and ingots of the same alloy, and that, for castings, properties can vary significantly between processes. For more detail, the appropriate standard(s) should be consulted.
