2 2000 series aluminum plate Represents 2A16 (LY16) 2A06 (LY6) 2000 series aluminum plate is characterized by high hardness, among which the original content of copper is the highest, about 3-5%. The 2000 series of aluminum sheets are aerospace aluminum and are currently not commonly used in conventional industries. There are fewer manufacturers of 2000 series aluminum sheets in China. Quality is still not comparable to foreign countries. Currently imported aluminum sheets are mainly supplied by Korean and German manufacturers. With the development of China's aerospace industry, the 2000 series of aluminum sheet production technology will be further improved.
Three 3000 series aluminum plates represent 3003 3003 3A21. It can also be called rust-proof aluminum plate. China 3000 series aluminum plate production process is relatively excellent. The 3000 series aluminum plate is mainly composed of manganese. The content is between 1.0 and 1.5. It is a series with better anti-rust function. Conventional applications in the humid environment of air conditioners, refrigerators, and car bottoms, the price is higher than 1000 series, is a more common alloy series.
Four 4000 Series Aluminum Plates The aluminum plates represented by the 4A01 4000 series are among the higher silicon content series. Typically the silicon content is between 4.5 and 6.0%. It is a building material, mechanical parts, forging materials, welding materials; low melting point, good corrosion resistance, heat and wear resistance.
The five 5000 series represents the 5052.5005.5083.5A05 series. The 5000 series aluminum plate belongs to the more common alloy aluminum plate series. The main element is magnesium, and the magnesium content is between 3-5%. Also known as aluminum-magnesium alloy. The main features are low density, high tensile strength and high elongation. The weight of aluminum-magnesium alloy is lower than other series under the same area. Therefore, it is commonly used in aviation, such as aircraft fuel tanks. It is also widely used in conventional industries. The processing technology is continuous casting and rolling, which belongs to the hot-rolled aluminum plate series and can be used for oxidation deep processing. In China, 5000 series aluminum plates belong to one of the more mature aluminum plate series.
The six 6000 series represents 6061 mainly containing magnesium and silicon. Therefore, the advantages of 4000 series and 5000 series are concentrated. 6061 is a cold-processed aluminum forged product suitable for applications requiring high corrosion resistance and oxidation resistance. Good usability, excellent interface characteristics, easy coating and good processability. Can be used on low pressure weapons and aircraft joints. General characteristics of 6061: excellent interface characteristics, easy coating, high strength, good workability and strong corrosion resistance. Typical uses for 6061 aluminum: aircraft parts, camera parts, couplers, marine parts and hardware, electronic parts and fittings, decorative or various hardware, hinged heads, magnetic heads, brake pistons, hydraulic pistons, electrical parts, valves and valve parts .
The seven 7000 series represents 7075 mainly containing zinc. Also belonging to the aviation series, it is an aluminum-magnesium-zinc-copper alloy, which is a heat-treatable alloy. It belongs to super-hard aluminum alloy and has good wear resistance. The 7075 aluminum plate is stress-relieved and will not deform or warp after processing. All super-super The thick 7075 aluminum plate is ultrasonically detected to ensure no blisters and impurities. The 7075 aluminum plate has high thermal conductivity, which can shorten the molding time and improve work efficiency. The main feature is that the hardness of 7075 is a high hardness, high strength aluminum alloy, commonly used in the manufacture of aircraft structures and futures. It requires high-strength structural parts and molds with high strength and high corrosion resistance. At present, it basically relies on imports, and China's production process needs to be improved.
