What is 3003 Aluminum Alloy?

3003 aluminum alloy is a typical Al-Mn alloy, renowned for its excellent formability, corrosion resistance, and weldability. This alloy is commonly used in a wide range of applications, including the manufacturing of lightweight automotive power battery enclosures, cookware, food storage devices, and transportation equipment such as tanks and containers. Its versatility makes it a popular choice for various industrial and consumer applications.

Composition and Technical Properties

3003 aluminum alloy primarily consists of aluminum (Al) and manganese (Mn), which gives it its unique properties. The typical composition includes approximately 0.05-0.20% copper, 1.0-1.5% manganese, and a balance of aluminum. This composition enhances its strength and corrosion resistance compared to pure aluminum.

The alloy exhibits a tensile strength of approximately 145-195 MPa and an elongation of 20%. Its excellent ductility and strength make it suitable for applications requiring complex shaping and forming.
