Aluminum Alloys France | A7-U 4 SG

A7-U 4 SG is a high-strength, heat-treatable aluminum-copper alloy with added silicon and other elements to enhance wear resistance, machinability, and thermal stability. It offers excellent mechanical properties and is particularly suited for forged components in aerospace, automotive, and mechanical engineering where high static and dynamic loads occur. While its corrosion resistance is lower compared to other aluminum alloys, it can be improved through anodizing or coating processes. At Rosswag, we use advanced open-die forging and precision machining to produce robust components from A7-U 4 SG. Its strength, stability, and wear resistance make it a reliable material for demanding structural and engine-related applications.
