Aluminum Alloys France | A-U 4 G

A-U 4 G is a heat-treatable aluminum-copper alloy with approximately 4% copper, known for its high strength, good machinability, and solid fatigue resistance. It is commonly used in aerospace, automotive, and mechanical engineering applications where forged components must withstand high mechanical loads and dynamic stresses. While its corrosion resistance is lower compared to other aluminum alloys, this can be improved through surface treatments. At Rosswag, we produce high-performance forged parts from A-U 4 G using advanced open-die forging and precision machining. Its strength and reliability make it a trusted material for structural applications in demanding industrial environments.
