Copper and Copper Alloy Ingots and Castings—BS EN 1982 and Comparison with BS 1400

The cast copper alloys are generally manufactured using BS EN 1982 specification for Copper and Copper Alloy Ingots and Castings (replacing the withdrawn BS 1400).  In the table below, the copper alloy grades are listed in numerical order based on their European designation and their respective alloy group. The nearest old BS designation (where applicable) has been included for comparison purposes and a basic material composition is listed under the ISO description. Note that for some old BS designations, there are no EN equivalents.

There are five main manufacturing methods in BS EN 1982 and the general production method associated with each alloy grade is shown in the last five columns on the right hand side. The method of manufacture will be an important factor in the mechanical performance of the alloy and, depending on the chosen method, will define mechanical and physical properties as well as other aspects such as surface finish.

However, please note that some of the alloys listed are not currently included in any manufacturing specifications. They are included for completeness, as the alloy still exists and can be specified on agreement with a manufacturer.

BS EN numbers and symbols for ingots and castings

Note that the BS EN numbers for castings begin with CC and the symbols end in C. For ingots, the same designations apply but with the prefix CB and the symbols end in B. Ingots are not specified for high conductivity coppers. Note that the method of casting affects the properties significantly.

See tables for full details of compositions, typical properties, characteristics and uses of copper and copper alloy castings.

How to use the table
