Aluminum Alloys USA | AA 3103

AA 3103 is a manganese-alloyed aluminum grade known for its excellent corrosion resistance, good formability, and moderate strength. It is particularly well-suited for applications in the construction and HVAC industries, such as roofing panels, cladding, and heat exchangers, where both durability and shaping flexibility are required. The alloy offers good weldability and is often chosen for components that are exposed to atmospheric or mildly aggressive environments. At Rosswag, we use advanced open-die forging and precision machining techniques to produce high-quality components from AA 3103. Its balance of corrosion resistance, workability, and cost-effectiveness makes it a reliable material for forged aluminum solutions in demanding environments.
