1. Classification and Use of Aluminum Rods
1.1. 1000 Series Aluminum Rods
1000 series aluminum rods, represented by 1050, 1060 and 1100, have extremely high purity, which can reach more than 99.00%. Because they do not contain other alloying elements, this series of aluminum rods has been widely used in conventional industries. The 1050 and 1060 series aluminum rods circulating on the market account for a considerable proportion. The naming of this series of aluminum rods follows the international grade rules. For example, the aluminum content of the 1050 series aluminum rod must reach more than 99.5% to be considered a qualified product.
1.2. 2000 Series Aluminum Rods
2000 series aluminum rods, such as 2A16 and 2A02, are known for their high hardness. Among them, the content of copper is about 3-5%, making it a type of aviation aluminum. Although it is less used in conventional industries, 2024 aluminum rods, as a hard aluminum alloy in the aluminum-copper-magnesium series, have excellent strength, processability and corrosion resistance.
1.3. 3000 Series Aluminum Rods
3000 Series Aluminum Rods, mainly 3003 and 3A21, are characterized by a manganese content between 1.0-1.5%, which gives it excellent anti-rust properties. The production process of this series of aluminum rods has been well developed in my country.
1.4. 4000 Series Aluminum Rods
4000 Series Aluminum Rods, such as 4A01, contain a higher silicon content, usually between 4.5-6.0%. This makes it an ideal choice for building materials, mechanical parts, forging materials, and welding materials. Its low melting point, corrosion resistance, heat resistance, and wear resistance also make it a place in the market.
1.5. 5000 Series Aluminum Rods
5000 Series Aluminum Rods, including 5052, 5005, 5083, and 5A05, use magnesium as the main alloying element, with a content between 3-5%. This series of aluminum bars has low density, high tensile strength and elongation, making it widely used in routine work. In my country, the production process of 5000 series aluminum bars is quite mature.
1.6. 6000 series aluminum bars
6000 series aluminum bars, such as 6061 and 6063, combine the advantages of 4000 and 5000 series. They contain magnesium and silicon elements, which make this aluminum bar both high strength and easy to process and coat. In particular, 6061 aluminum bars are suitable for applications with high requirements for corrosion resistance and oxidation resistance.
1.7. 7000 series aluminum bars
7000 series aluminum bars, represented by 7075, contain zinc elements. It belongs to the aviation series aluminum material with high strength and wear resistance. Although the price is high and it is basically dependent on imports, its high performance makes it indispensable in certain specific applications.
