3XXX Series

aluminum rods are mainly composed of manganese. 3000 series aluminum alloy represents 3003, 3105 and 3A21. The content is between 1.0-1.5, which is a series with good antirust function.

It is often used as tanks and tanks for liquid products, building processing parts, building tools, various lamp parts, and various pressure vessels and pipelines for sheet processing. Good formability, solubility and corrosion resistance.

4XXX Series

Generally, the silicon content is between 4.5-6.0%, and the strength is relatively high when the silicon content is high. The aluminum plates represented by 4a01 and 4000 series of 4000 series aluminum rods belong to the series with high silicon content. Good soup flow, less solidification shrinkage, belonging to building materials, mechanical parts, forging materials and welding materials; Low melting point, good corrosion resistance, heat resistance and wear resistance.

5XXX Series

5000 series aluminum rod belongs to the commonly used alloy aluminum plate series. The main element is magnesium, and the magnesium content is between 3-5%. 5000 series aluminum alloy represents 5052, 5005, 5083 and 5A05 series. It can also be called aluminum magnesium alloy. The main features are low density, high tensile strength and high elongation. Under the same area, the weight of aluminum magnesium alloy is lower than that of other series, and it is also widely used in conventional industry.

5052, the most commonly used alloy on mobile phones, is the most representative alloy with medium strength. It has good corrosion resistance, solubility and formability, especially high fatigue strength and good seawater resistance. It is often used as products with high strength requirements, but its coloring effect is not ideal. It is suitable for sand blasting process, not for chemical sanding, fog surface, etc. it is mainly formed by casting, Not suitable for extrusion.

6XXX Series

6000 series aluminum alloy represents 6061, which mainly contains magnesium and silicon, so it integrates the advantages of 4000 series and 5000 series. 6061 is a cold-treated aluminum forging product, which is suitable for applications with high corrosion resistance and oxidation requirements. Good usability, easy coating and good processability.

7XXX Series

It mainly contains zinc, and 7000 series aluminum alloy represents 7075. It also belongs to Aviation series. It is aluminum magnesium zinc copper alloy, heat treatable alloy, superhard aluminum alloy and has good wear resistance. At present, it basically depends on imports, and China's production technology needs to be improved 

8XXX Series

8011 is commonly used in 8000 Series aluminum alloy, which belongs to other series. Most applications are aluminum foil, which is not commonly used in the production of aluminum rods.
