Aluminum Sheet
Aluminum Al: balance; Silicon Si: ≤0.40; Copper Cu: ≤0.10;
Magnesium Mg: 3.5～4.5; Zinc Zn: ≤0.25; Manganese Mn: 0.20～0.7;
Titanium Ti: ≤0.15; Chromium Cr: 0.05～0.25; Iron Fe: 0.000～ 0.500
Note: Individual: ≤0.05; Total: ≤0.15. The same is true for 5251 aluminum sheet.
5251 is often used as a material for rail transit equipment. In particular, 5251 aluminum sheet has good medium strength and hardness. Magnesium-containing alloys have corrosion resistance, cold working can improve weldability and are easy to process and form. It is the best among aluminum Al-magnesium Mg alloys. Best partner for typical alloy combination. The 5251 aluminum sheet in different heat treatment and quenching states before leaving the factory is used as the main material for structural parts in the automotive manufacturing industry and reduces weight.
It is very good in terms of structural parts on rail transit and transportation or aerospace aluminum products. It reduces the weight of equipment and plays an important role in environmental protection and high-tech energy saving, especially in terms of pressure and chemical transportation. , high corrosion resistance and weldability, the service life is also greatly improved, and it also has outstanding characteristics in terms of strength. 5251 aluminum sheet is often used in welded structural engineering, storage tank welding, pressure vessel manufacturing, overall structural parts of ships and anti-corrosion parts for offshore facilities, especially for transport tanks with high corrosion resistance of aluminum alloy 5251 and for imported aluminum sheet 5251 It has excellent processing performance, excellent corrosion resistance, high fatigue strength, high weldability and medium to strong strength, and plays a representative role in light alloys.
It has been processed and processed through multiple procedures before leaving the factory, so that the material can play a more prominent and better performance effect. The surface of the material has been treated, and H112 and H111 are used as standards in the quenching treatment. The surface water marks and rolling marks have also been processed in the factory. Subsurface cleaning allows users to save more space and unnecessary waste of materials, regardless of internal or external quality. Mingtai Aluminum has always set a high starting point as its standard. No cracks, corrosion spots or nitrate traces are allowed on the surface before leaving the factory, and no traces of work are allowed on the surface. The surface should be protected by film and manual operation.
The 5000 series represents the 5052.5005.5083.5A05 series. The 5000 series aluminum plate belongs to the more commonly used alloy aluminum plate series. The main element is magnesium, and the magnesium content is between 3-5%. It can also be called aluminum-magnesium alloy. The main features are low density, high tensile strength and high elongation. The weight of aluminum-magnesium alloy is lower than other series under the same area. Therefore, it is often used in aviation, such as aircraft fuel tanks. It is also widely used in conventional industries. The processing technology is continuous casting and rolling, and it belongs to the hot-rolled aluminum plate series, so it can be used for deep oxidation processing. In my country, the 5000 series aluminum plate is one of the more mature aluminum plate series.
