1. According to the main alloying elements, the alloy aluminum plate can be divided into 2××× series for aluminum copper alloy aluminum plate (Al--Cu), 3××× series for aluminum manganese alloy aluminum plate (Al--Mn), 4××× series Aluminum-silicon alloy aluminum plate (Al--Si), 5××× series is aluminum-magnesium alloy aluminum plate (Al--Mg), 6××× series is aluminum-magnesium-silicon alloy aluminum plate (AL--Mg--Si), The 7××× series is aluminum-zinc alloy aluminum plate [AL--Zn--Mg--(Cu)].
2. Alloy aluminum plates can be divided into binary alloy aluminum plates, ternary alloy aluminum plates, quaternary alloy aluminum plates and multi-element alloy aluminum plates according to element units.
3. According to whether the alloy aluminum plate can be strengthened by heat treatment, it can be divided into heat treatment strengthened alloy aluminum plate and non-heat treatment strengthened alloy aluminum plate. Non-strengthened aluminum alloy plates can be strengthened only by cold working, but heat treatment cannot be significantly strengthened.
2××× series
2××× series alloy aluminum plate: represents 2A16 (LY16), 2A06 (LY6). The 2××× series aluminum plate is characterized by high hardness, among which the copper element content is the highest, about 3-5%. 2××× series aluminum plates belong to aviation aluminum materials, which are not often used in conventional industries at present. With the development of aerospace industry, 2××× series aluminum plate production technology will be further improved.
3××× series
3××× series alloy aluminum plate: mainly represents 3003 aluminum plate, 3004 aluminum plate, and 3A21 aluminum plate. It can also be called anti-rust aluminum plate. my country's 3××× series aluminum plate production technology is relatively excellent. 3××× series aluminum plate is made of manganese as the main component. The content is between 1.0-1.5%. It is a series with better anti-rust function. It is conventionally used in humid environments such as air conditioners, refrigerators, and undercars. The price is higher than the 1××× series. It is a more commonly used alloy series.
4××× series
4××× series alloy aluminum plate: representative is 4A01. It belongs to the series with higher silicon content. Usually the silicon content is between 4.5-6.0%. It belongs to construction materials, mechanical parts, forging materials, welding materials; low melting point, good corrosion resistance. Product description: It has the characteristics of heat resistance and wear resistance.
5××× series
5××× series alloy aluminum plate: represents 5052 aluminum plate, 5005 aluminum plate, 5083 aluminum plate, 5A05 aluminum plate series. The 5××× series aluminum plate belongs to the more commonly used alloy aluminum plate series, the main element is magnesium, and the magnesium content is between 3-5%. It can also be called 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 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, so it can be used for deep oxidation processing. In China, the 5××× series aluminum plate is one of the more mature aluminum plate series.
6××× series
6××× series alloy aluminum plate: represents 6061 aluminum plate and 6063 aluminum plate. It mainly contains two elements of magnesium and silicon, so the advantages of 4××× series and 5××× series are concentrated. 6061 is a cold-treated aluminum forging product, suitable for applications with high requirements for corrosion resistance and oxidation. Good workability, excellent interface characteristics, easy coating, and good processability. It can be used on low-pressure weapons and aircraft joints.
The general characteristics of 6061: excellent interface characteristics, easy coating, high strength, good workability, and strong corrosion resistance. Typical uses: 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××× series
7××× series alloy aluminum plate: on behalf of 7075. Mainly contains zinc. It also belongs to the aviation series. It is an aluminum-magnesium-zinc-copper alloy, a heat-treatable alloy, and a super hard aluminum alloy with good wear resistance. The 7075 aluminum plate is stress-relieved and will not be deformed or warped after processing. All ultra-large and ultra-thick All 7075 aluminum plates are ultrasonically detected, which can ensure no blisters and impurities. The high thermal conductivity of 7075 aluminum plates can shorten the forming time and improve work efficiency. The main feature is that the hardness of 7075 is a high-hardness, high-strength aluminum alloy, which is often used to make airplanes.
