Aluminum alloy 1000-8000 series

Date: 2019-05-11 09:25
The alloy aluminum plate is added with various alloying elements during the processing of the aluminum plate (the main alloying elements are copper, silicon, magnesium, zinc, manganese, and the secondary alloying elements are nickel, iron, titanium, chromium, lithium, etc.). Improve the mechanics of aluminum sheet properties and chemical specifications.
1. Alloy aluminum plate can be divided into 2××× series aluminum-copper alloy aluminum plate (Al-Cu) according to the main alloying elements. 3××× is an aluminum-manganese alloy aluminum plate (Al-Mn). 4××× series aluminum-silicon alloy aluminum plate (Al-Si). The 5××× system is an aluminum-magnesium alloy aluminum plate (Al-Mg). The 6××× system is an aluminum-magnesium-silicon alloy aluminum plate (AL-Mg-Si). 7××× is an aluminum-zinc alloy aluminum plate [AL - Zn - Mg - (Cu)].
The alloy aluminum plate can be divided into binary alloy aluminum plate, ternary alloy aluminum plate, quaternary alloy aluminum plate and multi-alloy aluminum plate according to the component unit.
3. Alloy aluminum plate can be divided into heat-resistant strengthened alloy aluminum plate and non-heat-treated strengthened alloy aluminum plate according to heat treatment. The alloy aluminum plate cannot be strengthened and can only be strengthened by cold working. The heat treatment cannot be significantly enhanced.
Alloy aluminum plate manufacturers detailed introduction
2××× series alloy aluminum plate
2××× series alloy aluminum plate: represents 2A16 (LY16), 2A06 (LY6). The 2××× series aluminum plates are characterized by high hardness, and the copper content is up to about 3-5%. The 2××× series aluminum plates are aerospace aluminum materials and are not commonly used in conventional industries. China currently produces 2××× series aluminum sheets with fewer manufacturers. The quality cannot be compared with foreign countries. Imported aluminum sheets are mainly produced in Korea and Germany. Provided by the company. With the development of China's aerospace industry, 2××× series aluminum sheet production technology will be further improved.
3××× series alloy aluminum plate
3××× series alloy aluminum plates: respectively represent 3003 aluminum plates, 3004 aluminum plates and 3A21 aluminum plates. It can also be called a rust-proof aluminum plate. China 3××× series aluminum plate production process is excellent. The 3××× series aluminum plate is mainly composed of manganese. The content is between 1.0 and 1.5%. It is a series with better rust prevention. Traditional applications are in humid environments such as air conditioners, refrigerators and car bottoms. The price is higher than the 1××× series. It is a commonly used alloy series.
4××× series alloy aluminum plate
4××× series alloy aluminum plate: represents 4A01. It belongs to the series of high silicon content. Usually the silicon content is between 4.5 and 6.0%. It belongs to building materials, mechanical parts, forged materials, welding materials and low melting point, corrosion resistant. Corrosive product description: heat and abrasion resistance.
5××× series alloy aluminum plate
5××× series alloy aluminum plate: representing 5052 aluminum plate, 5005 aluminum plate, 5083 aluminum plate, 5A05 aluminum plate series. The 5××× series aluminum plates belong to the more common alloy aluminum plate series. The main component is magnesium, and the magnesium content is 3-5%. It can also be called an aluminum-magnesium alloy. The main features are low density, high tensile strength and high elongation. In the same area, the weight of aluminum-magnesium alloy is lower than other series. Therefore, it is often used in aviation, such as aircraft fuel tanks. Applications in traditional industries are also extensive. The processing technology is continuous casting and rolling, which belongs to the series of hot-rolled aluminum sheets, which can be used for oxidative deep processing. in China,
6××× series alloy aluminum plate
6××× series alloy aluminum plate: represents 6061 aluminum plate and 6063 aluminum plate. It mainly contains two elements of magnesium and silicon, so it concentrates on the advantages of the 4××× series and the 5××× series. 6061 is a cold forged aluminum forged product. It is suitable for applications with high corrosive and oxidizing requirements. It has good processability, excellent interface properties, easy coating and good processability. It can be used for low pressure weapons and aircraft joints.
General characteristics of 6061: excellent interface properties, easy coating, high strength, good processability and strong corrosion resistance. Typical uses: aircraft parts, camera parts, couplers, marine parts and hardware, electronic parts and connectors, decorative objects or various hardware, hinged heads, magnetic heads, brake pistons, water pistons, electrical accessories, valves and valves Components.
7××× series alloy aluminum plate
7××× series alloy aluminum plate: representing 7075. Mainly containing zinc element, belonging to aviation series, aluminum magnesium zinc copper alloy, heat treatment alloy. It is a super-hard aluminum alloy with good wear resistance. The 7075 aluminum plate was eliminated. The stress does not deform or warp after treatment. All ultra-thick and extra-thick 7075 aluminum panels are ultrasonically tested 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 features are high hardness and high strength aluminum alloy. It is usually used to make airplanes.
