3003 aluminum is one of the most commonly used aluminum alloys because of its high resistance to corrosion. 3003 aluminum is alloyed with a combination of copper, iron, manganese, silicon, and zinc. Because of its manganese content, 3003 aluminum is 20% stronger than 1100-grade aluminum alloys. This alloy is usually rolled and extruded, and typically not forged due to its wrought form. While 3003 aluminum alloy is not suitable for heat treatments but can be strengthened with cold working. 3003 aluminum is commonly used in fuel tanks and sheet metal work such as radiators, heat shields, roofing, and siding.
Our 3003 aluminum scrap is collected from manufacturing plants and not post-consumption waste. Therefore, they are free from impurities and the recycling process is fairly simple. It has moderate strength and good workability.
