Aluminum alloy selection by application

Translate the application into material priorities

A marine hull cares about seawater corrosion and welding. A CNC part cares about machining stability. A decorative panel cares about finish and flatness. These are different buying problems.

Ask process questions early

Will the material be welded, bent, machined, anodized, painted or exposed outdoors? Each answer can change the recommended alloy and temper.

For a complete selection framework, see the alloy guide by application.
