3003 aluminum bar is an aluminum-manganese (Al-Mn) alloy known for its excellent corrosion resistance, good machinability, and superior welding performance. With a typical composition of 96.8–99% aluminum and 1.0–1.5% manganese, it offers medium strength and is non-heat-treatable, relying on cold working to enhance its mechanical properties.
