According to different processing technology, it can be divided into cold rolling and hot rolling.
According to the different thickness, it can be divided into thin plate and medium thick plate. The aluminum foil with thickness less than 0.2mm specified in GB / t3880-2006 is called aluminum foil. Commonly used brand: pure aluminum plate, strip. Foil. Thick plate, stretch tube. Squeeze the tube. Type. Great. Cold processed bar is mainly used in the situation of high corrosion resistance and formability, but not high strength parts, such as chemical equipment, ship equipment, railway tank car, conductive material, instrument material, welding rod, etc.
3003: plate and strip. Foil. Plate. Stretch the tube. Squeeze the tube. Type. Great. wire rod. Cold working bar, cold working wire, rivet wire, forging, radiator material. It is mainly used for processing parts requiring good molding performance, high corrosion resistance, or weldability, or parts requiring these properties and higher strength than 1 *, such as tanks and tanks for liquid transportation, pressure tanks, storage devices, heat exchangers, chemical equipment, aircraft oil tanks, oil ducts, reflectors, kitchen equipment, washing machine cylinder, rivets, welding Silk. Aluminum clad 3003 alloy: plate, thick plate, stretch tube. Extrusion pipe house partition, top cover, pipeline, etc. 3004: plate, thick plate, tensile pipe. As long as the extruded tube is used for the whole aluminum can body, it requires higher parts than 3003 alloy, chemical product production and storage device, sheet metal processing parts, building baffles, cable ducts, sewers, various lighting parts.
3004 aluminum clad alloy: plate and thick plate are mainly used for building partition, baffle, sewer, roof cover of industrial building 5052: plate, thick plate, foil, tensile pipe, cold processed bar, cold processed wire, rivet wire. This alloy has good forming and processing performance, corrosion resistance, weldability, fatigue strength and medium static strength, and is used for making aircraft oil tank and oil pipe , as well as traffic vehicles, ship’s sheet metal parts, instruments, street lamp brackets and rivet wires, etc. 6061: plate, thick material, tensile pipe. Extrusion pipe, bar, profile, wire, conduit, rolled or extruded structural profile, cold processed bar, cold processed wire, rivet wire, forging. All kinds of industrial structural parts with certain strength, corrosion resistance and high weldability are required, such as pipes, bars and profiles for manufacturing trucks, tower buildings, ships, trams, railway vehicles, furniture, etc.
According to the classification of aluminum plate brand, according to the different metal elements contained in the aluminum plate, we will introduce it gradually.
1. The 2000 series aluminum plate represents 2A16 (Ly16) 2A12 (LY12) 2A06 (LY6) 2000 series aluminum plate, which is characterized by high hardness, of which the copper element content is the highest, about 3-5%. 2000 series aluminum plate belongs to aviation aluminum material, which is not often used in conventional industry at present. At present, there are few manufacturers of 2000 series aluminum plates in China. The quality cannot be compared with that of foreign countries. At present, the imported aluminum plates are mainly provided by Korean and German manufacturers. With the development of China’s aerospace industry, the production technology of 2000 series aluminum plate will be further improved.
In such humid environment, the price is higher than 1000 series, which is a more commonly used alloy series.
2. 5000 series represents 5052.5005.5083.5a05 series. 5000 series aluminum plate belongs to the commonly used alloy aluminum plate series, the main element is magnesium, and the magnesium content is between 3-5%. Also known as aluminum magnesium alloy. It is characterized by low density, high tensile strength and high elongation. In the same area, the weight of aluminum magnesium alloy is lower than other series, so it is often used in aviation, such as aircraft fuel tank. It is also widely used in conventional industry. The processing technology is continuous casting and rolling, belonging to the hot rolling aluminum plate series, so it can do deep oxidation processing. In China, 5000 series aluminum plate belongs to one of the more mature aluminum plate series.
3. 6000 series represents 6061, which mainly contains two elements of magnesium and silicon. Therefore, 6061 is a cold-treated aluminum forging product with the advantages of 4000 series and 5000 series. It is suitable for applications with high requirements of corrosion resistance and oxidation resistance. The utility model has the advantages of good usability, excellent interface characteristics, easy coating and good processability. It can be used on low-pressure weapons and aircraft joints. General features of 6061: excellent interface features, easy coating, high strength, good usability, strong corrosion resistance. Typical uses of 6061 aluminum: aircraft parts, camera parts, couplers, ship accessories and hardware, electronic accessories and joints, decorative or various hardware, hinge head, magnetic head, brake piston, hydraulic piston, electrical accessories, valves and valve parts.
4. The 7000 series represents the 7075 mainly containing zinc. It also belongs to the aviation series. It is an aluminum magnesium zinc copper alloy. It is a heat-treatment alloy. It belongs to super hard aluminum alloy. It has good wear resistance. 7075 aluminum plate is stress relieved and will not deform or warp after processing. All super thick 7075 aluminum plates are detected by ultrasonic, which can ensure no sand holes and impurities. 7075 aluminum plate has high thermal conductivity, can shorten forming time and improve working efficiency.
The main feature is that the hardness of 7075 is a high hardness and high strength aluminum alloy, which is commonly used to manufacture aircraft structures and futures. It requires the manufacture of high stress structural parts and dies with high strength and corrosion resistance. At present, China’s production process still needs to be improved. (a foreign company in our company once proposed that the annealing of 7075 aluminum plate made in China is uneven, and the surface and internal hardness of aluminum plate are inconsistent.).
