One series: 1000 series aluminum alloys represent 1050, 1060 and 1100 series. Among all the series, the 1000 series belongs to the series with the most 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 industries at present. Most of the current circulation in the market are 1050 and 1060 series. The minimum aluminum content of the 1000 series
aluminum plate 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 more to qualify as a product. China's aluminum alloy technical standard (gB/T3880-2006) also clearly stipulates that the aluminum content of 1050 should reach 99.5%. In the same way, the aluminum content of 1060 series aluminum plates must reach more than 99.6%.
Second series: 2000 series aluminum alloys represent 2024, 2A16 (LY16), 2A02 (LY6). The 2000 series aluminum plate is characterized by high hardness, among which the copper content is the highest, about 3-5%. The 2000 series aluminum rods belong to aviation aluminum and are not commonly used in conventional industries at present.
Three series: 3000 series
aluminum alloys mainly represent 3003 and 3A21. my country's 3000 series aluminum plate production process is relatively good. 3000 series aluminum rods are made of manganese as the main component. The content is between 1.0-1.5, which is a series with better anti-rust function.
Four series: 4000 series aluminum rods are represented by 4A01 4000 series aluminum plates, which belong to the series with high silicon content. Usually the silicon content is between 4.5-6.0%. It belongs 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
Five series: 5000 series aluminum alloys represent 5052, 5005, 5083, 5A05 series. 5000 series aluminum rods belong to the more commonly used alloy
aluminum plate 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, high elongation, and good fatigue strength, but it cannot be strengthened by heat treatment. Under the same area, the weight of aluminum-magnesium alloy is lower than other series. It is also widely used in conventional industries. In my country, the 5000 series aluminum plate belongs to one of the more mature aluminum plate series.
Six series: 6000 series aluminum alloy represents 6061, which mainly contains two elements of magnesium and silicon, so the advantages of 4000 series and 5000 series are concentrated. 6061 is a cold-processed aluminum forged product, suitable for applications requiring high corrosion resistance and oxidation resistance. Good workability, easy coating, good processability.
Seven series: 7000 series aluminum alloys represent 7075 mainly containing zinc. It also belongs to the aviation series. It is an aluminum-magnesium-zinc-copper alloy. It is a heat-treatable alloy. It belongs to superhard aluminum alloy and has good wear resistance. It also has good weldability, but poor corrosion resistance. At present, it basically relies on imports, and China's production technology needs to be improved.
Eight series: 8000 series aluminum alloy is more commonly used as 8011 belongs to other series, most of the application is aluminum foil, and the production of aluminum rod is not commonly used.
Nine series: 9000 series aluminum alloys are spare alloys.
