5xxx series aluminium sheet represents 5052, 5005, 5083, 5A05 series. 5000 series aluminum plate belongs to the more commonly used alloy aluminum plate series, the main element is magnesium, the magnesium content is between 3-5%. It can also be called aluminum-magnesium alloy. The main characteristics are low density, high tensile strength, high elongation, good fatigue strength, but can not do heat treatment to strengthen. In the same area, the weight of aluminum and magnesium alloy is lower than other series. In the conventional industry is also more widely used. In our country 5000 series aluminum plate belongs to one of the more mature aluminum plate series.

The 4xxx series aluminum sheet is represented as 4A01. The 4000 series aluminum sheet is a series with high silicon content. Usually the silicon content is between 4.5-6.0%. It is a material for construction, machinery parts, forging and welding; low melting point, good corrosion resistance, Product description: It has the characteristics of heat resistance and wear resistance of patterned aluminum sheet.
