According to the different metal elements contained in aluminum rods, aluminum rods can be divided into eight categories
1、 1000 series aluminum bars represent 1050, 1060 and 1100 series. In all series, 1000 series belongs to a series with more 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 a series commonly used in conventional industry. Most of the 1050 and 1060 series are in circulation on the market. The * low aluminum content of 1000 series aluminum bar is determined according to the last two Arabic numerals of * for example, the last two Arabic numerals of 1050 series * are 50. According to the naming principle of * * brand, the product with aluminum content above 99.5% must be qualified. China's technical standard for aluminum alloy (GB / t3880-2006) also clearly stipulates that the aluminum content of 1050 should reach 99.5%. Similarly, the aluminum content of 1060 series aluminum bars must reach 99.6%.
2、 2000 series aluminum bars represent 2A16 (Ly16) and 2A02 (LY6). 2000 series aluminum bar is characterized by high hardness, in which the copper content * is high, about 3-5%. 2000 series aluminum rods are aviation aluminum materials, which are rarely used in conventional industry.
2024 is a typical duralumin alloy in Al Cu mg system. It is a heat treatable alloy with high strength, easy machining, easy turning and general corrosion resistance.
After heat treatment (T3, T4, t351), the mechanical properties of 2024 aluminum bar are significantly improved. The 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, rivets, truck hub, propeller components and other structural parts
3、 3000 series aluminum bar represents 3003 and 3A21. The production process of 3000 series aluminum rods in China is relatively * *. 3000 series aluminum rods are mainly composed of manganese. The content is between 1.0-1.5, which is a series with better antirust function.
4、 4000 series aluminum bars represent 4a01, 4000 series aluminum bars belong to the series with high silicon content. Generally, 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, product description: it has the characteristics of heat resistance and wear resistance
5、 5000 series aluminum bar represents 5052, 5005, 5083, 5A05 series. 5000 series aluminum bar belongs to the more commonly used alloy aluminum bar series, the main element is magnesium, and the magnesium content is between 3-5%. It can also be called aluminum magnesium alloy. The main features are low density, high tensile strength and high elongation. In the same area, the weight of Al Mg alloy is lower than other series, and it is widely used in conventional industry. In China, 5000 series aluminum bar is one of the more mature aluminum bar series.
6、 The 6000 series aluminum bar represents 6061 and 6063, 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 requirements of corrosion resistance and oxidation resistance. Good usability, easy coating and good processability.
7、 7000 series aluminum bar represents 7075, which mainly contains zinc. It also belongs to Aviation series. It is al mg Zn Cu alloy. It is heat treatable alloy. It is super hard aluminum alloy with good wear resistance. It basically depends on imports. The production process in China needs to be improved.
8、 8011 is more commonly used in 8000 Series aluminum bar, which belongs to other series. Most of them are used in aluminum foil, but they are not commonly used in the production of aluminum bar.
