Aluminum Strip Alloy 3003 in Rolls is one of the most widely used manganese-containing aluminum strip products in the 3xxx series. It offers an excellent balance of corrosion resistance, formability, weldability, and moderate strength, making it an ideal material for heat exchangers, roofing systems, insulation jacketing, transformer windings, cookware, automotive components, and general industrial manufacturing.
Compared with commercially pure aluminum such as 1050 or 1060, 3003 aluminum strips provide higher mechanical strength while maintaining outstanding workability. The addition of approximately 1.0–1.5% manganese significantly improves durability without sacrificing forming performance, allowing the alloy to be easily stamped, bent, rolled, and deep drawn.
Whether you are looking for 3003-O aluminum, reviewing the 3003 H14 aluminum properties, comparing technical specifications, or searching for the latest 3003 aluminum sheet price, this guide provides everything you need before purchasing Aluminum Strip Alloy 3003 in Rolls.
1. What Is Aluminum Strip Alloy 3003 in Rolls?
3003 aluminum strip is an aluminum-manganese alloy produced through hot rolling, cold rolling, and precision slitting into narrow coils. Because of its excellent corrosion resistance and outstanding forming capability, it has become one of the most popular aluminum strip materials for industrial production.
The alloy is commonly supplied in tempers such as 3003-O, H12, H14, H16, and H18. Among them, 3003 H14 aluminum offers an excellent balance between strength and formability, making it suitable for roofing, insulation, transportation equipment, cookware, electrical components, and decorative applications.
Manufacturers typically supply aluminum strip in coil form to improve production efficiency and reduce material waste during stamping, bending, and continuous processing.
2. Chemical Composition of 3003 Aluminum Alloy
The excellent corrosion resistance and forming performance of 3003 aluminum mainly come from its balanced chemical composition. Manganese is the primary alloying element, increasing strength while maintaining excellent ductility and weldability.
Element | Content (%) | Function |
| Aluminum (Al) | Balance | Base metal |
| Manganese (Mn) | 1.0–1.5 | Improves strength and corrosion resistance |
| Copper (Cu) | 0.05–0.20 | Enhances mechanical properties |
| Silicon (Si) | ≤0.60 | Residual element |
| Iron (Fe) | ≤0.70 | Residual element |
This composition enables aluminum alloy 3003 rolled products to combine excellent corrosion resistance with reliable mechanical performance, making them suitable for a wide range of industrial applications.
3. Mechanical Properties of 3003 Aluminum Strip
The excellent balance between strength and formability is one of the biggest advantages of Aluminum Strip Alloy 3003 in Rolls. Although it is not a heat-treatable alloy, cold working significantly improves its mechanical properties while maintaining excellent ductility and corrosion resistance.
Among the available tempers, 3003 H14 aluminum is the most commonly used because it provides moderate strength and excellent forming performance for industrial processing.
Property | Typical Value | Unit |
| Density | 2.73 | g/cm³ |
| Ultimate Tensile Strength | 140–180 | MPa |
| Yield Strength | 115–145 | MPa |
| Elongation | 8–12 | % |
| Thermal Conductivity | 193 | W/m·K |
| Electrical Conductivity | 40 | % IACS |
The combination of moderate 3003 aluminum yield strength, excellent corrosion resistance, and high aluminum 3003 thermal conductivity makes this alloy suitable for HVAC equipment, heat exchangers, insulation materials, and various formed components.
4. 3003-O vs 3003-H14
The most common tempers for 3003 aluminum strips are O (annealed) and H14 (strain-hardened). Selecting the correct temper depends on whether your application prioritizes maximum formability or higher mechanical strength.
Comparison | 3003-O | 3003-H14 |
| Temper | Annealed | Half Hard |
| Strength | Lower | Higher |
| Formability | Excellent | Very Good |
| Deep Drawing | Excellent | Good |
| Typical Applications | Cookware, containers | Roofing, insulation, heat exchangers |
If extensive forming or deep drawing is required, 3003-O aluminum is generally the preferred choice. For applications requiring improved rigidity while maintaining good workability, 3003-H14 aluminum sheet offers the best balance of strength and fabrication performance.
