A brief analysis of the specific classification criteria for aluminum alloys with typical uses of different grades of aluminum alloys

Classification of aluminum alloy

One series: 1000 series aluminum alloys represent 1050, 1060, 1100 series. The 1000 series is the most aluminum-containing series in all series. The purity can reach above 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 the conventional industry. Most of the current circulation on the market is the 1050 and 1060 series. The 1000 series aluminum plates are based on the last two Arabic numerals to determine the minimum aluminum content of the series. For example, the last two Arabic numerals of the 1050 series are 50. According to the international brand nomenclature, the aluminum content must reach 99.5% to be qualified products. China's aluminum alloy technical standards (gB/T3880-2006) also clearly stipulates that the aluminum content of 1050 reaches 99.5%. The same reason, the aluminum content of the 1060 series aluminum plate must reach 99.6% or more.

Second series: 2000 series aluminum alloy stands for 2024, 2a16 (LY16), 2a02 (LY6). The 2000 series aluminum plate is characterized by high hardness, and the copper content is the highest, about 3-5%. The 2000 series of aluminum rods are aerospace aluminum and are currently not commonly used in conventional industries.

Three series: 3000 series aluminum alloy stands for 3003 and 3a21. China's 3000 series aluminum sheet production process is relatively good. The 3000 series aluminum rods are mainly composed of manganese. The content is between 1.0 and 1.5, which is a series with better anti-rust function.

Four series: 4000 series aluminum rods represent 4a01 4000 series aluminum sheets belong to the series with higher silicon content. Typically the silicon content is between 4.5 and 6.0%. It is a building material, mechanical parts, forging materials, welding materials; low melting point, good corrosion resistance, product description: heat-resistant, wear-resistant

Five series: 5000 series aluminum alloy represents 5052, 5005, 5083, 5a05 series. 5000 series aluminum rods belong to the more common alloy aluminum plate series. The main element is magnesium, and the magnesium content is between 3-5%. Also known as aluminum-magnesium alloy. The main features are low density, high tensile strength and high elongation. The weight of aluminum-magnesium alloy is lower than other series under the same area. It is also widely used in conventional industries. In China, 5000 series aluminum plates belong to one of the more mature aluminum plate series.

Six series: 6000 series aluminum alloy represents 6061 mainly contains magnesium and silicon two elements, so the advantages of 4000 series and 5000 series are concentrated. 6061 is a cold-processed aluminum forged product, which is suitable for applications with high corrosive and oxidizing requirements. Good workability, easy coating and good processability.

Seven series: 7000 series aluminum alloy represents 7075 mainly contains zinc. Also belonging to the aviation series, it is an aluminum-magnesium-zinc-copper alloy, which is a heat-treatable alloy. It belongs to super-hard aluminum alloy and has good wear resistance. At present, it basically relies on imports, and China's production process needs to be improved.

Eight series: 8000 series aluminum alloy is more commonly used for 8011. It belongs to other series. Most of the applications are aluminum foil. It is not very common for producing aluminum rods.

Nine series: 9000 series aluminum alloy is a spare alloy.
