How Many Series Aluminum Alloys?

Aluminum alloy is the most widely used non-ferrous structural materials in the industry, and has been widely used in aviation, aerospace, automotive, machinery manufacturing, shipbuilding and chemical industries.

There are nine categories of aluminum alloy from 1 to 9.

A series: 1000 series aluminum alloy represents 1050, 1060, 1100 series. In all series, the 1000 series belongs to the series with the most aluminum content. Purity can reach more than 99.00%. Because it does not contain other technical elements, the production process is relatively single, the price is relatively cheap, and it is the most commonly used series in conventional industry. At present, most of the 1050 and 1060 series are in circulation on the market.

1000 series aluminum plate according to the last two Arabic numerals to determine the minimum aluminum content of this series, such as the last two Arabic numbers of 1050 series is 50, according to the international brand naming principle, the aluminum content must reach 99.5% or more for qualified products. China's aluminum alloy technical standard (gB/T3880-2006) also clearly stipulates that the aluminum content of 1050 reaches 99.5%. In the same way, the aluminum content of the 1060 series aluminum plate must reach more than 99.6%.

The second series: 2000 series aluminum alloy represents 2024, 2A16 (LY16), 2A02 (LY6). The 2000 series aluminum plate is characterized by high hardness, of which the copper original content is the highest, about 3-5%. The 2000 series aluminum rod is an aviation aluminum material, which is not often used in conventional industry.

Three series: 3000 series aluminum alloy represents 3003, 3A21 mainly. China's 3000 series aluminum plate production process is more excellent. 3000 series aluminum rod is made of manganese element as the main component. The content is between 1.0-1.5, which is a series with good anti-rust function.

Four series: 4000 series aluminum rod represents 4A01 4000 series aluminum plate belongs to the series with higher silicon content. The silicon content is usually between 4.5-6.0%. It belongs to building materials, forging materials for mechanical parts, welding materials; Low melting point, good corrosion resistance, product description: with heat resistance, wear resistance

Five series: 5000 series aluminum alloy represents 5052, 5005, 5083, 5A05 series. 5000 series aluminum rod belongs to the more commonly used alloy aluminum plate series, the main element is magnesium, and the magnesium content is between 3-5%. Can also be called aluminum magnesium alloy. The main characteristics are low density, high tensile strength, high elongation and good fatigue strength, but it can not be strengthened by heat treatment. Under the same area, the weight of aluminum magnesium alloy is lower than that of other series. It is also widely used in conventional industry. 5000 series aluminum plate is one of the more mature aluminum plate series in China.

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 treatment aluminum forging products, suitable for applications with high corrosion resistance and oxidation requirements. Good usability, easy coating, good processability.

Seven series: 7000 series aluminum alloy represents 7075 mainly containing zinc. Also belongs to the aviation series, is aluminum magnesium zinc copper alloy, is heat treatable alloy, belongs to super hard aluminum alloy, has good wear resistance. It also has good weldability, but poor corrosion resistance.

Eight series: 8000 series aluminum alloy is more commonly used 8011 belongs to other series, most of the application is aluminum foil, the production of aluminum rod is less commonly used.

Nine series: 9000 series aluminum alloy is a spare alloy. Aluminum alloy is the most widely used non-ferrous structural materials in the industry, and has been widely used in aviation, aerospace, automotive, machinery manufacturing, shipbuilding and chemical industries.
