The characteristics and application fields of different types of aluminum profiles are different, so I suggest you know the characteristics and application fields of aluminum profiles first, and then compare and buy them!
Three, aluminum alloy specification model 9 series
According to the different metal elements contained in aluminum plates, aluminum plates can be divided into 9 categories, namely 9 series. Let's introduce it step by step.
1 and 1000 series aluminum plates1050106010701000 series aluminum plates, also called pure aluminum plates. In all series, 1000 series belongs to the series with the most aluminum content. The purity can reach above 99.00%.
2.2000 series aluminum plate represents 2A16 (LY16) 2A12 (LY12) 2000 series aluminum plate is characterized by high hardness, in which the copper content is the highest, about 3-5%. 2000 series aluminum plate belongs to aviation aluminum, which is not often used in conventional industry.
3.3000 series aluminum plates represent 300330033A2 1. It can also be called rust-proof aluminum plate. The production technology of 3000 series aluminum plates in China is excellent. 3000 series aluminum plates are mainly composed of manganese. The content is between 1.0- 1.5.
4.4000 series aluminum plates, represented by 4A0 14000 series aluminum plates, belong to high silicon content series. Generally, the silicon content is between 4.5 and 6.0%. Belonging to building materials, mechanical parts, forging materials and welding materials; Low melting point and good corrosion resistance. Product description: it has the characteristics of heat resistance and wear resistance.
5.5000 series represents 5052.5005.5083.5A05 series. In China, 5000 series aluminum plates belong to one of the more mature aluminum plates.
6.6000 series stands for 606 1 and mainly contains magnesium and silicon, so it combines the advantages of 4000 series and 5000 series. 606 1 is a cold-treated aluminum forging product.
606 1 General features: excellent interface characteristics, easy painting, high strength, good usability and strong corrosion resistance.
Typical uses of 606 1 aluminum: aircraft parts, camera parts, couplers, ship parts and hardware, electronic parts and connectors, decorative or various hardware, hinge heads, magnetic heads, brake pistons, hydraulic pistons, electrical accessories, valves and valve parts.
7.7000 series represents 7075, mainly containing zinc. It also belongs to the aviation series. It is an Al-Mg-Zn-Cu alloy, which is a heat-treatable alloy and is often used to manufacture aircraft structures and futures. It requires the manufacture of high-stress structural parts and molds with high strength and strong corrosion resistance. Basically dependent on imports, China's production technology needs to be improved. A foreign company in our company has suggested that the annealing of domestic 7075 aluminum plate is uneven, and the hardness of aluminum plate surface and interior is inconsistent.
8.8000 series is often used as 80 1 1 and belongs to other series. I remember aluminum plate, which is mainly used to make bottle caps and radiators, mostly aluminum foil. Not very common.
9.9000 series belongs to standby series, and the technology is so developed. In order to cope with the appearance of aluminum plates containing other alloying elements, the International Federation of Aluminum Plate and Strip specially marked the 9000 series as a standby series, waiting for another new variety to appear to fill the blank of the 9000 series.
Fourth, the characteristics of aluminum series
1 system: containing more than 99.00% aluminum, it has good conductivity, good corrosion resistance, good weldability and low strength, and cannot be strengthened by heat treatment. Uses: High-purity aluminum (containing more than 99.9% aluminum) is mainly used for scientific experiments, chemical industry and special purposes.
Series 2: Aluminum alloy with copper as the main alloying element. Manganese, magnesium, lead and bismuth are also added for machinability. For example: 20 1 1 alloy, safety protection should be paid attention to during melting and tempering (harmful gas will be generated). 20 14 alloy is used in aerospace industry with high strength. The strength of 20 17 alloy is lower than that of 20 14 alloy, but it is easier to process. 20 14 can be strengthened by heat treatment. Disadvantages: serious tendency of intergranular corrosion. Scope of application: aviation industry (20 14 alloy), screws (20 1 1 alloy) and industries with high service temperature (20 17 alloy).
Series 3: Aluminum alloy with manganese as the main alloying element can not be strengthened by heat treatment, and has good corrosion resistance and weldability. Good plasticity. (close to super aluminum alloy). Disadvantages: the strength is low, but it can be strengthened by cold working and hardening. Coarse grains are easily produced during annealing. Scope of application: Seamless oil guide tube (3003 alloy) and tank (3004 alloy) for aircraft.
Series 4: mainly silicon, not commonly used. The fourth part can be strengthened by heat treatment, but some 4 series alloys cannot be heat treated. human resources
Series 5: mainly magnesium. Good corrosion resistance, good weldability and good fatigue strength, which can not be strengthened by heat treatment, but can only be improved by cold working. Uses: mower handle, aircraft fuel tank catheter, bulletproof vest.
Series 6: mainly magnesium and silicon. Mg2Si is the main strengthening phase and the most widely used alloy at present. 6063,6061is used the most, and others are 6082,6160,6125,6262,6060,6005,6463. 6063, 6060 and 6463 are relatively weak in the 6 series. 6262, 6005, 6082, 606 1 have higher strength in line 6. Characteristics: medium strength, good corrosion resistance, good welding performance, good technological performance (easy extrusion) and good oxidation coloring performance. Application: energy transfer tools (such as car luggage rack, door, window, car body, radiator, car shell).
Series 7: mainly zinc, but sometimes a small amount of magnesium and copper are added. Among them, superhard aluminum alloy contains zinc, lead, magnesium and copper alloy close to steel hardness. The extrusion speed is slower than that of 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. Applications: aviation (load-bearing parts of aircraft, landing gear), rockets, propellers and spaceships.
Eight series: 80 1 1, commonly used in aluminum alloy, belonging to other series, mostly used in aluminum foil, not often used in aluminum bar production.
Nine series: aluminum alloy is a spare alloy.
