The difference between 3003 and 3004 aluminum plates
The difference between 3003 and 3004 aluminum plate is introduced:
With the pursuit of various properties of aluminum plates, the demand for 3003 aluminum plates has gradually increased. When many customers buy 3003 aluminum plates, the sales manager of some aluminum plate manufacturers will recommend 3004 aluminum plates. Many customers don’t know the difference between the 3003 and 3004 aluminum plates. So today, Mingtai will explain the difference between 3003 aluminum plates and 3004 aluminum plates for you. You better understand these two aluminum alloys.
3003 aluminum plate introduction:
3003 aluminum sheet belongs to 3XXX aluminum sheet, both in terms of sales volume and user acceptance, which are currently a better product. 3003 aluminum plate is usually called an anti-rust aluminum plate. 3003 aluminum plate has manganese alloy elements, which is superior to conventional 1 series aluminum plate in anti-rust performance. At present, the most common applications of 3003 aluminum plates on the market are high-speed traffic signs, building signs, high-speed barriers, building shells, etc., which are all popular applications of 3003 aluminum plates. The performance of the 3003 aluminum plate is better than that of 1 series aluminum plate such as a 1060 aluminum plate and an 1100 aluminum sheet. At the same time, the 3003 aluminum plate has the advantages of good formability, high hardness, and rust prevention.
3004 aluminum plate introduction:
3004 aluminum plate also belongs to the 3XXX series aluminum plate, which is consistent with the basic aspects of 3003 aluminum plate alloy. However, the strength of the 3004 aluminum sheet is higher than that of the 3003 aluminum sheet, which is better in terms of corrosion resistance and product formability. It has high formability, solubility, corrosion resistance, processing formability, and excellent performance in anti-corrosion devices. This is one of the reasons why many projects are gradually abandoning 3003 aluminum plates and adopting 3004 aluminum plates.
The difference between 3003 aluminum plate and 3004 aluminum plate:
1.The chemical composition difference between 3003 aluminum plate and 3004 aluminum plate
3003 aluminum plate chemical composition: silicon Si: 0.60; iron Fe: 0.70; copper Cu: 0.05-0.20; manganese Mn: 1.0-1.5; zinc Zn: 0.10; others: single 0.05; total 0.15. 3004 aluminum plate chemical composition: aluminum Al balance; silicon Si: 0.30; copper Cu: 0.25; magnesium Mg: 0.8 ~ 1.3; zinc Zn: 0.25; manganese Mn: 1.0 ~ 1.5; Fe: 0.7. Through these we can easily see that the chemical composition of 3004 aluminum plate is higher than 3003 aluminum plate. At the same time, “magnesium element Mg” is also a major difference in chemical composition between 3003 aluminum plate and 3004 aluminum plate.
2.The performance difference between 3003 aluminum plate and 3004 aluminum plate
The mechanical properties of 3003 aluminum plate are tensile strength σb (MPa)) 142-178, and conditional yield strength σ0.2 (MPa) )≥115. The mechanical properties of the 3004 aluminum plate are tensile strength σb (MPa): 150～285, elongation δ10 (%): 1～16. Through comparison, it is not difficult to see that the performance difference between 3003 aluminum plate and 3004 aluminum plate is still very big, especially for some qualitative differences in tensile strength.
