ALUMINIUM ALLOYS

ALUMINIUM ALLOYS

The range of aluminium alloys is extensive and the choice of alloy used in any single application depends greatly on the properties derived from the trace metallic elements present within the alloy.

Care should be taken when considering which alloy to use for your application will depend on the properties that will be need in the end product.

Here are just a few examples of the more commonly specified aluminium alloys.
