Aluminum Practitioners Must Know – Aluminium Alloy Series

Aluminum alloy A general term for aluminum based alloys. The main alloy elements are copper, silicon, magnesium, zinc, manganese, and the secondary alloy elements are nickel, iron, titanium, chromium, lithium, etc.

Aluminum alloy has low density but high strength, which is close to or better than high-quality steel. It has good plasticity and can be processed into various profiles. It has excellent conductivity, thermal conductivity and corrosion resistance. It is widely used in industry, and its usage is only second to that of steel.

Aluminium Alloy Series

Aluminium Alloy Series

1××× Pure aluminum plate: the common codes of pure aluminum plate series are 1050, 1060 and 1100. Among all aluminum plate series, pure aluminum plate series belongs to the series with the highest aluminum content. The purity can reach 99.00%. Because it does not contain other technical elements, the production process is relatively simple and the price is relatively cheap. It is the most commonly used series of products in traditional industries. At present, 1050 and 1060 series are mostly circulating in the market.

2××× Alloy aluminum plate: 2 ××× Series alloy aluminum plate: 2A16 (Ly16), 2A06 (LY6). 2××× The series aluminum plates have high hardness, among which the original copper content is the highest, about 3-5%. two ××× The series aluminum plate belongs to aviation aluminum and is not often used in conventional industry.

3××× Alloy aluminum plate: 3003 aluminum plate, 3004 aluminum plate, 3A21 aluminum plate. 3××× Series aluminum plates are mainly manganese, with a content of 1.0-1.5%. This series of products have good rust resistance. It is generally used in humid environments such as air conditioners, refrigerators and car bottoms, and the price is higher than 1 ××× Series is a commonly used alloy series.

4××× Series alloy aluminum plate: represented by 4A01. It belongs to high silicon series. Generally speaking, the silicon content is between 4.5% and 6.0%. It belongs to building materials, mechanical parts, forging materials and welding materials; Low melting point, good corrosion resistance.

5××× Series alloy aluminum plate: representing 5052 aluminum plate, 5005 aluminum plate, 5083 aluminum plate and 5A05 aluminum plate series. 5××× The series aluminum plate belongs to ordinary alloy aluminum plate series. The main element is magnesium, which is 3-5%. It is also called aluminum magnesium alloy. Its main characteristics are low density, high tensile strength and high elongation. In the same area, aluminum magnesium alloy is lighter than other series. Therefore, it is often used in aviation, such as aircraft fuel tank. It is also widely used in traditional industries. The processing technology is continuous casting and rolling, which belongs to the hot-rolled aluminum plate series and can be used for deep oxidation processing. In China, 5 ××× Series aluminum plate is one of the more mature aluminum plate series. 5××× The series alloy aluminum plate has good drawing effect.

6××× Series alloy aluminum plate: representing 6061 aluminum plate and 6063 aluminum plate. 6061 is a cold treated aluminum forging product, which is suitable for occasions with high requirements for corrosion resistance and oxidation resistance. Good usability, good interface characteristics, easy coating and good processability. It can be used for low pressure weapons and aircraft joints.

7××× Series alloy aluminum plate: 7075. It mainly contains zinc. 7075 aluminum plate is stress relieved and does not deform or warp after processing. All super large and super thick 7075 aluminum plates can be tested by ultrasonic to ensure that there are no sand holes and impurities. The high thermal conductivity of 7075 aluminum sheet can shorten the forming time and improve the working efficiency. The main feature is that the hardness of 7075 is an aluminum alloy with high hardness and strength, which is commonly used in aircraft manufacturing.
