Graphic Details
Aluminum rods can be roughly divided into eight major categories based on the metallic elements they contain, which can be divided into the following series:
I. The 1000 series aluminum rods represent the 1050, 1060, and 1100 series. Among all series, the 1000 series has the highest aluminum content. The purity can reach more than 99.00%. Due to the lack of other technical elements, the production process is relatively simple, and the Price is relatively cheap. It is the most commonly used series in conventional industries. Most of the products circulating in the market are the 1050 and 1060 series. The minimum aluminum content of the 1000 series aluminum rods is determined by 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 more than 99.5% to be a qualified product. China's aluminum alloy technical standard (GB/T3880-2006) also clearly stipulates that the aluminum content of 1050 reaches 99.5%. Similarly, the aluminum content of 1060 series aluminum rods must reach more than 99.6%.
II. The 2000 series aluminum rods are represented by 2A16 (LY16) and 2A02 (LY6). The 2000 series aluminum rods are characterized by high hardness, with copper as the main element, accounting for about 3-5%. The 2000 series aluminum rods belong to aviation aluminum materials and are not commonly used in conventional industries.
2024 is a typical hard aluminum alloy in the aluminum-copper-magnesium system. It is a heat-treatable alloy with high strength, easy processing, easy machining, and general corrosion resistance.
After heat treatment (T3, T4, T351), the mechanical properties of 2024 aluminum rods 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 Applications of 2024 aluminum rods: aircraft structures, rivets, truck hubs, propeller components, and Others structural parts.
III. The 3000 series aluminum rods are mainly represented by 3003 and 3A21. China's 3000 series aluminum rod production technology is relatively excellent. The 3000 series aluminum rods are mainly composed of manganese, with a content between 1.0 and 1.5, and is a series with good rust prevention function.
IV. The 4000 series aluminum rods are represented by 4A01. The 4000 series aluminum rods have a high silicon content, usually between 4.5 and 6.0%. They are used for building materials, mechanical parts, forging materials, and welding materials; they have a low melting point and good corrosion resistance. Description: It has heat resistance and wear resistance.
V. The 5000 series aluminum rods represent the 5052, 5005, 5083, and 5A05 series. The 5000 series aluminum rods are a commonly used series of alloy aluminum rods, with magnesium as the main element, with a magnesium content between 3 and 5%. It can also be called aluminum-magnesium alloy. Its main characteristics are low density, high tensile strength, and high elongation. Under the same area, the weight of the aluminum-magnesium alloy is lower than that of other series, and it is also widely used in conventional industries. In China, the 5000 series aluminum rods are one of the more mature aluminum rod series.
VI. The 6000 series aluminum rods are represented by 6061 and 6063, mainly containing magnesium and silicon, thus combining the advantages of the 4000 and 5000 series. 6061 is a cold-treated aluminum forging product suitable for applications with high corrosion and oxidation resistance requirements. It has good usability, easy coating, and good machinability.
VII. The 7000 series aluminum rods are represented by 7075, mainly containing zinc. It also belongs to the aviation series, is an aluminum-magnesium-zinc-copper alloy, is a heat-treatable alloy, belongs to super-hard aluminum alloy, and has good wear resistance. It mainly relies on imports, and China's production technology still needs to be improved.
VIII. The commonly used 8000 series aluminum rod is 8011, which belongs to other series and is mostly used for aluminum foil; it is not commonly used in aluminum rod production.
