Copper alloy flat bar / rectangular bar

Copper alloy rectangular flat bars. Available in different sizes.

Data sheet: Copper alloy flat bar / rectangular bar

The alloyed copper bars that we manufacture at Bronmetal are subject to the EN 13601 Standard that applies to products made of copper and copper alloys. Specifically to copper bars and wires for general electrical uses. Combinations of copper with other elements improve the performance of the bars in specific applications. Depending on the type of alloy, the copper bar will have certain characteristics and specifications, but, in general terms, it improves corrosion resistance and has high electrical and thermal conductivity.

The choice of the type of alloyed copper strip will depend on the type of application and the desired performance requirements. In the technical data sheet section you can consult the details of the chemical compositions for each of the alloys, as well as the technical characteristics, equivalences and nominal thickness tolerances for the entire range of thicknesses available.
