Aluminum-magnesium-manganese alloy grade 3004 is based on the addition of manganese and magnesium to ordinary aluminum. The aluminum alloy produced has better tensile strength, yield strength and elongation than ordinary aluminum. Its tensile strength and yield strength have doubled that of ordinary aluminum, and its anti-oxidation and corrosion performance has also been further enhanced. It is called anti-rust aluminum in the metal industry, so 3004 Al-Mn-Mg alloy has anti-rust and high strength Features, wide range of uses.
The following table is the difference in performance of 3003 VS 3004 aluminum alloy
| Name | Alloy&Temper | Tensile strength (Mpa) | Yield strength (Mpa) | Elongation (%) |
| Al-Mn | 3003 H24 | 135-175 | ≥120 | ≥3 |
| Al-Mg-Mn | 3004 H24 | 220-265 | ≥170 | ≥3 |
