1、 The 1000 series aluminum bars represent 1050, 1060 and 1100 series. Among all the series, the 1000 series is the one with the highest aluminum content. The purity can reach more than 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 in conventional industry at present. Most of the products in circulation on the market are 1050 and 1060 series. The minimum aluminum content of the 1000 series aluminum rod is determined according to the last two Arabic numerals. For example, the last two Arabic numerals of the 1050 series are 50. According to the international brand naming principle, the aluminum content must reach 99.5% or above. China's aluminum alloy technical standard (gB/T3880-2006) also clearly stipulates that the aluminum content of 1050 series aluminum rods must reach 99.5%. In the same way, the aluminum content of 1060 series aluminum rods must reach more than 99.6%.
2、 2000 series aluminum bars represent 2A16 (LY16) and 2A02 (LY6). The 2000 series aluminum bars are characterized by high hardness, with the highest content of copper, about 3-5%. The 2000 series aluminum rods belong to aviation aluminum materials and are not often used in conventional industry.
2024 is a typical duralumin alloy in the aluminum-copper-magnesium system. It is a heat-treatable alloy with high strength, easy processing, easy turning and general corrosion resistance.
After heat treatment (T3, T4, T351), the mechanical properties of 2024 aluminum bar are significantly improved, and its T3 state parameters are as follows: tensile strength 470MPa, 0.2% yield strength 325MPa, elongation: 10%, fatigue strength 105MPa, hardness 120HB.
Main uses of 2024 aluminum rod: aircraft structure, rivet, truck hub, propeller assembly and other structural parts
3、 The 3000 series aluminum bars mainly represent 3003 and 3A21. The production process of 3000 series aluminum bars in China is excellent. The 3000 series aluminum rod is mainly composed of manganese. The content is between 1.0 and 1.5, which is a series with good anti-rust function.
4、 The 4000 series aluminum rods represent the 4A01 4000 series aluminum rods, which belong to the series with high silicon content. Generally, the silicon content is between 4.5-6.0%. It belongs to construction materials, mechanical parts, forging materials and welding materials; Low melting point, good corrosion resistance, product description: heat resistant and wear-resistant
5、 5000 series aluminum bars represent 5052, 5005, 5083 and 5A05 series. The 5000 series of aluminum rods belong to the more commonly used alloy aluminum rod series. The main element is magnesium, and the magnesium content is between 3-5%. It can also be called aluminum magnesium alloy. The main characteristics are low density, high tensile strength and high elongation. The weight of Al-Mg alloy is lower than other series in the same area, and it is also widely used in conventional industry. In China, the 5000 series aluminum rod is one of the more mature aluminum rod series.
6、 The 6000 series aluminum bars represent 6061 and 6063, which mainly contain magnesium and silicon. Therefore, the advantages of the 4000 series and 5000 series are concentrated. 6061 is a cold-treated aluminum forging product, suitable for applications with high requirements for corrosion resistance and oxidation. Good usability, easy coating and good processability.
7、 The 7000 series aluminum rod represents 7075, which mainly contains zinc. It also belongs to aviation series. It is aluminum magnesium zinc copper alloy. It is a heat-treatable alloy. It belongs to superhard aluminum alloy and has good wear resistance Basically relying on imports, China's production technology needs to be improved.
8、 The 8011 series of 8000 series aluminum bars is more commonly used. It belongs to other series, and most of the applications are aluminum foil. It is not commonly used in the production of aluminum bars.
