Product classification of aluminum bars

1, The 1000 series aluminum bars represent the 1050, 1060, and 1100 series. The 1000 series belongs to the series with the highest aluminum content among all series. The purity can reach over 99.00%. Due to the absence of other technological elements, the production process is relatively simple and the price is relatively cheap, making it the most commonly used series in conventional industry. The majority of products circulating in the market are the 1050 and 1060 series. The minimum aluminum content of the 1000 series aluminum rod is determined based on 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 as a qualified product. The aluminum alloy technical standard (GB/T3880-2006) in our country also clearly stipulates that the aluminum content of 1050 should reach 99.5%. Similarly, the aluminum content of 1060 series aluminum rods must reach 99.6% or above.
2, The 2000 series aluminum bars represent 2A16 (LY16) and 2A02 (LY6). The characteristic of the 2000 series aluminum rod is its high hardness, with the highest copper content, approximately 3-5%. The 2000 series aluminum bars 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 series, which is a heat-treatable alloy with high strength, easy processing, easy turning, and average corrosion resistance.
After heat treatment (T3, T4, T351), the mechanical properties of 2024 aluminum bars significantly improved. The T3 state parameters are as follows: tensile strength 470MPa, 0.2% yield strength 325MPa, elongation: 10%, fatigue strength 105MPa, hardness 120HB.
The main uses of 2024 aluminum bars: aircraft structures, rivets, truck hubs, propeller components, and various other structural components
3, The 3000 series aluminum bars represent mainly 3003 and 3A21. The production process of 3000 series aluminum bars in China is relatively excellent. The 3000 series aluminum rod is mainly composed of manganese element. The content is between 1.0 and 1.5, which is a series with good rust prevention function.
4, The 4000 series aluminum rod represents 4A01. The 4000 series aluminum rod belongs to the series with higher silicon content. The silicon content is usually between 4.5% and 6.0%. Belonging to building materials, mechanical parts, forging materials, welding materials; Low melting point, good corrosion resistance, product description: It has the characteristics of heat resistance and wear resistance
