3003 aluminum plate and 3004 aluminum plate are AL-Mn alloy, is the most widely used a rust-proof aluminum, can not heat treatment to strengthen, so the use of cold processing methods Improve its mechanical properties.
Differences in chemical composition (for reference)
3003 aluminum plate
Aluminum 3003 is alloyed with 1.2% maganese to provide a tensile strength range of 17 to 30 KSI.
3003 h14 aluminum sheet
3004 aluminium plate
The alloy 3004 is commonly used in the making of beverage cans. Can-stock can be made thinner due to the addition of 1% magnesium, which contributes in solid solution strengthening.
The chemical composition “Mg element” of 3004 aluminum plate is much higher than that of 3003 aluminum plate. At the same time, “magnesium element” is also the item with the biggest difference in chemical composition between 3003 aluminum plate and 3004 aluminum plate.

Differences in physical properties
How strong is 3003 aluminum sheet?
It has excellent corrosion resistance, workability, and it may be deep drawn or spun, welded or brazed. It is non heat treatable.
3003 aluminum sheet plate is not strong (slightly higher than industrial pure aluminum) and cannot be strengthened by heat treatment. Therefore, cold working methods are used to improve its mechanical properties.
3003 aluminum sheet has high plasticity in the annealed state and good plasticity in semi-cold working. Low hard mode, good corrosion resistance, good weldability, poor machinability.
How strong is 3004 aluminum sheet?
3004 alloy has moderate strength, good workability, and good corrosion resistance. It is commonly rolled and extruded, but typically not forged, not used in casting.
Differences in mechanical properties
| Item | Tensile strength (Rm/MPa) | Yield strength(Rp0.2/MPa) | Density |
| Alloy 3003 | 142-178 | 150～285 | 2.71 |
| Alloy 3004 | 150-285 | 110 |
The difference of use
What is 3003 aluminum plate used for?
What is 3004 aluminum plate used for?
Difference in temper
The temperer of 3003 has O, H12, H14, H16, H18, H22, H24.
Tempers H22 and H24 etc may not meet maximum tensile strength and minimum yield strength limits.
The tempers state of 3004 is more, F, H112, O, H111, H12, H22, H32, H14, H24, H34, H16, H26, H18, H19, H28, H38

Which is better, 3003 aluminum or 3004 aluminum?
3004 aluminum sheet is stronger than 3003 aluminum sheet, has excellent formability and good corrosion resistance. It needs higher strength than 3003 aluminum plate.
The density formula and calculation of 3003 aluminum plate are: length mm * width mm * height mm * 0.00000272.
How do I choose?
Alloy 3004 essentially has the identical necessities in all components with the 3003 aluminum plate, however its strength is better than that of alloy 3003. 3004 aluminum sheet is of the better formability, solubility, corrosion resistance. That’s why many projects steadily abandon 3003 aluminum sheet to select 3004 aluminum sheet.
In the actual application, we should choose the right aluminum plate according to our needs and Meet your needs with reasonable price.
