| Aluminum profile model series

1 series: 1000 series
contains more than 99.00% aluminum, has good electrical conductivity, good corrosion resistance, good welding performance, low strength, and cannot be strengthened by heat treatment. Applications: Mainly used for scientific experiments, chemical industry and special purposes.
2 series: 2000 series
aluminum alloy with copper as the main compound element. Manganese, magnesium, lead and bismuth are also added for machinability. Disadvantages: serious tendency of intergranular corrosion. Applications: Aviation industry (2014 alloys), screws (2011 alloys) and industries with higher operating temperatures (2017 alloys).
3 series: 3000 series
uses manganese as the main alloying element, with good corrosion resistance and good welding performance. Disadvantages: low strength, but can be strengthened by cold work hardening. Coarse grains are easily produced during annealing. Scope of application: Seamless oil pipe (3003 alloy) and pop can (3004 alloy) used on aircraft.
4 series: 4000 series
is mainly made of silicon, with high wear resistance, low thermal expansion coefficient, easy casting, and low or high silicon content will affect performance. Application range: It is widely used in the piston and cylinder of motor vehicles, and is widely used abroad.
5 series: 5000 series
is mainly magnesium. Good resistance, good welding performance, good fatigue strength, not heat treatment to strengthen, only cold processing to improve strength. Applications: lawn mower handles, aircraft fuel tank conduits, bulletproof vests.
6 Series: 6000 Series
is based on magnesium and silicon. Medium strength, good corrosion resistance, good welding performance, good process performance, good oxidation coloring performance. Application range: currently the most widely used alloy, transportation (such as: car luggage rack, door, window, body, heat sink, box shell).
7 series: 7000 series
is mainly zinc, but sometimes a small amount of magnesium and copper are added. 7005 and 7075 are the highest grade in the 7 series and can be strengthened by heat treatment. Applications: Aviation (aircraft load-bearing components, landing gear), rockets, propellers, aerospace vehicles.
other series:
8 series: 8000 series , aluminum alloy is more commonly used for 8011 belongs to other series, most of the application is aluminum foil, aluminum rod production is not commonly used.
9 series :9000 series , aluminum alloy is a spare alloy.

1. hardness
hardness first with the chemical composition of the alloy has a direct relationship. Second, different states also have a greater impact. 7 series, 2 series, 4 series, 5 series, 3 series, 1 series, in turn decreased.
2. strength
pure aluminum has the lowest strength, while 2 series and 7 series heat-treated alloys have the highest strength. Hardness and strength have a certain positive relationship.
3. Corrosion Resistance
Generally speaking, 1 series pure aluminum has the best corrosion resistance, 5 series performs well, followed by 6 series, 2 series and 7 series. The principle of corrosion resistance selection should be based on its use. The use of high-strength alloys in corrosive environments requires the use of a variety of corrosion-resistant composite materials.
4. processing performance
processing performance includes forming performance and cutting performance. Because the formability is related to the state, after selecting the aluminum alloy grade, the strength range of various states should be considered. Generally, the material with high strength is not easy to form.
If you want to bend, stretch, deep drawing and other forming processes for aluminum, the formability of the material in the fully annealed state is the best, and vice versa, the formability of the material in the heat treatment state is the worst. The cutting performance of
aluminum alloy has a great relationship with the alloy composition. Generally, the cutting performance of aluminum alloy with higher strength is better, on the contrary, the cutting performance of low strength is poor. For products that require cutting, such as molds and parts, the machinability of aluminum alloys is an important consideration.
5. welding performance
Most aluminum alloys have no problems in welding, especially some 5 series aluminum alloys, which are specially designed for welding considerations. Part of the 2 series and 7 series aluminum alloy is difficult to weld.
