Main uses of aluminum alloys

Because of its excellent physical properties, aluminum alloys has been widely used in various sectors of the national economy and national defense industry.

As a lightweight structural material, aluminum is light in weight and strong. Land, sea, and air vehicles, especially aircraft, missiles, rockets, satellites, etc., use a large amount of aluminum.
Various vehicles made of aluminum and aluminum alloys can reduce energy consumption due to their lightweight, and the energy saved far exceeds the energy consumed during aluminum smelting.
In the construction industry, aluminum alloy is used as the door, window, and structural material of the house, and solar energy collectors are made of aluminum, which can save energy.
In terms of power transmission, aluminum is the first to use, and 90% of high-voltage electrical wires are made of aluminum.
In the food industry, everything from warehouse storage tanks to cans to beverage containers is mostly made of aluminum.
In other aspects, aluminum powder is used as a reducing agent for refractory metals (such as molybdenum, etc.) and as a deoxidizer in the steelmaking process.
Pots, basins, spoons, etc. in daily life.

The international brand naming system for aluminum and aluminum alloys

Series 1: pure aluminum, aluminum content above 99.00%, good electrical conductivity, good corrosion resistance, good welding performance, low strength, not heat-treatable. Application range: high-purity aluminum (aluminum content above 99.9%) is mainly used in Scientific experiments, chemical industry, and special purposes.

2 Series: Aluminum alloy containing copper and Cu as the main element. Manganese, magnesium, lead, and bismuth are also added for machinability. Such as the 2011 alloy, pay attention to safety protection during the smelting process (hazardous gas will be generated). The 2014 alloy is used in the aviation industry with high strength. The 2017 alloy has a lower strength than the 2014 alloy, but it is easier to process. 2014 can be strengthened by heat treatment. The disadvantage is that the tendency of intergranular corrosion is serious. Mainly used in the aviation industry (2014 alloy), screws (2011 alloy), and industries with higher service temperatures (2017 alloy).

Series 3: The main alloying element is manganese Mn, which cannot be strengthened by heat treatment, has good corrosion resistance, good welding performance, and good plasticity. The disadvantage is that the strength is low, but it can be strengthened by cold work hardening, and it is easy to produce coarse grains during annealing. Mainly used for seamless oil pipes (3003 alloys) and cans (3004 alloys) on airplanes.

Series 4: The main alloying element is silicon Si, which is not commonly used. Some 4 series alloys can be strengthened by heat treatment, but some 4 series alloys cannot be heat treated.

Series 5: The main alloying element is magnesium Mg, which has good resistance performance, good welding performance, and good fatigue strength. It cannot be strengthened by heat treatment, and can only be cold-worked to increase the strength. Mainly used for the handles of lawnmowers, aircraft fuel tank ducts, and body armor.

Series 6: The main alloying elements are magnesium Mg and silicon Si. Mg2Si is the main strengthening phase and is currently the most widely used alloy. 6063, 6061 are most used, other 6082, 6160, 6125, 6262, 6060, 6005, 6463. The strength of 6063, 6060, and 6463 is relatively low in the 6 series. The 6262, 6005, 6082, 6061 have higher strength in the 6 series. It is characterized by medium strength, good corrosion resistance, good welding performance, good process performance (easy to be extruded and formed), and good oxidation and coloring performance. Mainly used for car luggage racks, doors, windows, car bodies, heat sinks, and compartment shells)

7 series: The main alloying element is zinc and Zn, but sometimes a small amount of magnesium and copper are added. Among them, super-hard aluminum alloys contain zinc, lead, magnesium, and copper alloys close to the hardness of steel. The extrusion speed is slower than that of the 6 series alloy, and the welding performance is good. 7005 and 7075 are the highest grades in the 7 series and can be strengthened by heat treatment. Application scope: aviation (plane’s load-bearing components, landing gear), rockets, propellers, aviation spacecraft.

Series 8: other elements

9 series: (spare alloy)

1XXX series means pure aluminum, the aluminum content is not less than 99.00%, and the last two digits mean two digits after the decimal point. The second digit indicates the control of the limit content of alloy elements or impurities. If the second digit is 0, it means that there is no special control on the limit content of impurities. If it is 1-9, it means that one or more items are individually controlled. The limit content of impurities or alloying elements is specially controlled.

The last two digits in the 2XXX-8XXX series have no special meaning and are only used to identify different alloys in the same group. The second digit indicates the modification situation, if the second digit is 0, it is expressed as the original alloy, and if it is 1-9, it is expressed as the modified alloy.
