Aluminum Alloys France | A-U 4 G 1

A-U 4 G 1 is a high-strength, heat-treatable aluminum-copper alloy with approximately 4% copper and additional elements for improved performance, offering excellent mechanical strength, good fatigue resistance, and reliable machinability. It is particularly suitable for aerospace and structural engineering applications where forged components are exposed to high static and dynamic loads. While its corrosion resistance is relatively low, protective surface treatments can enhance its durability in aggressive environments. At Rosswag, we manufacture precision-forged components from A-U 4 G 1 using advanced open-die forging and machining technologies. This alloy is ideal for critical parts requiring strength, dimensional stability, and performance under stress.
