First, the introduction of alloy aluminum plate:
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.) to improve the mechanics of the aluminum plate. Performance and chemical indicators. Alloy aluminum plate has some special properties that pure aluminum plate does not have, and is widely used in special environments, such as ships, refrigerators, molds, aerospace equipment and so on.
Second, alloy aluminum plate classification:
1. The alloy aluminum plate can be divided into 2××× series aluminum-copper alloy aluminum plate (Al--Cu) according to the main alloying elements, and 3××× series is aluminum-manganese alloy aluminum plate (Al--Mn), 4××× series It is an aluminum-silicon alloy aluminum plate (Al--Si), a 5××× system is an aluminum-magnesium alloy aluminum plate (Al--Mg), and a 6××× system is an aluminum-magnesium-silicon alloy aluminum plate (AL--Mg--Si). The 7××× system is an aluminum-zinc alloy aluminum plate [AL--Zn--Mg--(Cu)].
2. 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 element unit.
3. The alloy aluminum plate can be divided into heat treatable reinforced alloy aluminum plate and non-heat treatable reinforced alloy aluminum plate according to heat treatment. The alloy aluminum plate cannot be strengthened, and only cold working can be strengthened, and the heat treatment cannot be obviously strengthened.
Third, the alloy aluminum plate details:
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, among which the original content of copper is the highest, about 3-5%. The 2××× series aluminum plates are aerospace aluminum materials and are not commonly used in conventional industries. At present, there are fewer manufacturers producing 2××× series aluminum plates 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 2××× series of aluminum sheet production technology will be further improved.
3××× series alloy aluminum plate:
3××× series alloy aluminum plate: mainly represents 3003 aluminum plate, 3004 aluminum plate and 3A21 aluminum plate. It can also be called rust-proof aluminum plate. China's 3××× series aluminum plate production process is relatively excellent. The 3××× series aluminum plate is composed of manganese as the main component. 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 the 1××× series, which is a more commonly used alloy series.
4××× series alloy aluminum plate:
4××× series alloy aluminum plate: represented as 4A01 alloy aluminum plate. It belongs to the series with high silicon content. Usually 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. Product Description: 7075 aluminum plate with heat resistance and wear resistance (http://)
Pressure sensor usually consists of a pressure sensor and a signal processing unit for measuring the pressure of liquids and gases.
According to different test pressure types, pressure sensors can be divided into gauge pressure sensors, differential pressure sensors and absolute pressure sensors. According to the working principle, it can be divided into Ceramic Pressure Sensor, diffusion silicon pressure sensor, piezoresistive pressure sensor, sapphire pressure sensor and so on.
