As a representative alloy of the 3000 series aluminum-manganese alloys, 3003 is one of the most widely used anti-rust aluminum alloys worldwide. By adding manganese to pure aluminum, it achieves an excellent balance between strength and corrosion resistance.
3003 aluminum sheet uses aluminum as its base metal, with a small amount of manganese (Mn) as the primary alloying element. It is a versatile, medium-strength aluminum sheet material widely used in industrial applications due to its well-balanced overall properties.
Compared with pure aluminum alloys in the 1xxx series, 3003 aluminum sheet maintains good formability and corrosion resistance while offering significantly improved strength. It is widely used in architectural decoration, chemical equipment, transportation, and general industrial applications, making it one of the most commonly used basic aluminum alloys in engineering design.
HAOMEI Aluminum produces extra-wide and extra-thick 3003 aluminum sheets with internal stress relieved to prevent deformation after cutting. The maximum width is 2,650 mm, and the maximum thickness is 500 mm.
The typical chemical composition of 3003 aluminum sheet consists mainly of aluminum, with manganese content of approximately 1.0–1.5%. The addition of manganese effectively improves tensile strength and fatigue resistance without significantly reducing the material’s ductility or corrosion resistance.
This alloy design strengthens the material without sacrificing processability, enabling 3003 aluminum sheet to provide both strength and formability in practical applications.

Outstanding Anti-Rust Performance: 3003 is a true "anti-rust aluminum" alloy. It performs very reliably in humid environments, atmospheric conditions, and certain mildly acidic or alkaline media.
Excellent Deep Drawing and Formability: It is an ideal material for spinning and deep-drawing applications. Whether it is formed into rounded cookware or bent into complex piping components, 3003 aluminum can maintain a smooth surface without cracking.
Easy Welding: 3003 aluminum sheet is easy to weld. Gas welding, arc welding, and resistance welding can all be used, producing reliable weld strength.
Surface-Treatment Friendly: 3003 aluminum sheet is highly compatible with anodizing, painting, spraying, and coating processes, allowing attractive and durable surface finishes.
Good Balance Between Cost and Performance: Where very high strength is not required, 3003 aluminum sheet provides excellent cost performance and is a preferred material for general industrial applications.
Kitchen Applications: Cookware, pots, pressure cooker liners, rice cooker inner pots, and related products.
Transportation Applications: Automotive fuel tanks, truck fuel tanks, power-battery housings, and refrigerated container linings.
Building Exterior Applications: Color-coated aluminum coils, architectural curtain walls, and aluminum honeycomb panel substrates.
Chemical and Storage/Transportation Applications: Pressure vessels, liquid transfer pipes, storage tanks, and pressure tanks.
