Alloy | Main Elements |
A3003 | Aluminum (Al) with ~1.0–1.5% Manganese (Mn) |
A3004 | Aluminum (Al) with ~1.0–1.5% Manganese (Mn) and ~0.8–1.3% Magnesium (Mg) |
Property | A3003 | A3004 |
Tensile Strength | 130–170 MPa | 190–240 MPa |
Yield Strength | 115–145 MPa | 150–200 MPa |
Elongation | Higher ductility | Slightly less, but still good |
Formability | Excellent | Very good |
✅ Higher Strength – Magnesium addition makes A3004 significantly stronger than A3003.
✅ Better Load-Bearing Capacity – Ideal for applications requiring more structural support.
✅ Improved Corrosion Resistance – Performs better in aggressive environments.
✅ Good Formability – Though slightly less than A3003, A3004 still bends and shapes easily.
✅ Longer Service Life – Particularly useful for exterior applications like roofing and cladding.
A3004 is an upgraded version of A3003. If your application requires better strength and corrosion resistance, especially for coated aluminum products like roofing sheets, wall panels, or rain gutters, A3004 is the better choice.
