Rolled aluminum sheet can be roughly divided into several series, pure rolled aluminum sheet is 1000 series, alloy rolled aluminum sheet is 2-7 series. For example, 1060 belongs to the 1000 series, 2024 belongs to the 2000 series, 3105 aluminum sheet belongs to the 3000 series, 5005 belongs to the 5000 series, and so on. Although there are 8 series aluminum alloys, the 8 series aluminum alloys usually exist in the form of aluminum foil.
The 1000 series, as a pure aluminum sheet, has no complicated processing technology. Choose 1100, 1050 or 1060 alloy according to the project. The main element is aluminum, with a content of more than 99%.
The 2000 series is not used much in life, and its characteristics are determined by the copper element. According to the specific application, select the specific alloy, and the copper content of different alloys is 2%-5% or higher. This is also the reason for the high hardness of the 2000 series. The high hardness makes it can be used in aerospace and is considered to be aerospace aluminum. Since the 2000 series is not commonly used in life, not all aluminum sheet manufacturers can produce 2000 series alloy aluminum sheets, and the price is relatively high. Henan Mingtai Aluminum can provide 2 series aluminum sheet, if required, feel free to contact us.
The 3000 series is a familiar aluminum-manganese alloy. The manganese content is between 2-5%. Representative varieties of the 3000 series include 3003 aluminum sheet and 3a21 aluminum sheet. The 3000 series aluminum sheet has a certain anti-rust performance and is widely used in humid environments such as air conditioners and refrigerators. The price can be said to be the lowest price among alloy aluminum sheets.
4000 series, aluminum-silicon alloy, currently not widely used.
The 5000 series is too practical and versatile. There are mainly 5052 and 5083 grades. It is the most commonly used aluminum alloy sheet in my country and the world. Take the 5052 series as an example, there are many advantages.
a Lighter weight. The specific gravity of 5052 aluminum sheet is 2.68, and the weight of 5052 aluminum sheet under the same area is lower than that of other brands of aluminum sheet.
b. The tensile strength is high. The tensile strength of 5052 is higher than that of aluminum sheets of the same specification, and it has better resistance to deformation.
c. Good extensibility, the elongation rate of 5052 aluminum sheet is 15-30%, which can guarantee punching, bending, and good results.
d. The main alloying element is magnesium, which has the excellent properties of magnesium, and has good anti-corrosion and anti-rust effects, which is much higher than that of the 3003 series.
Some of the e.5052 series have excellent anodizing properties, which can further improve their chemical advantages. The 5052 series aluminum sheet is widely used, including precision electronic components, hardware building materials, anti-theft doors, etc. These applications generally require high strength and good corrosion resistance.
It is generally believed that the 6000 series combines the advantages of the 4000 and 5000 series, and the main alloying elements are silicon and magnesium. The representative grade is 6061-t6 aluminum sheet. This kind of aluminum sheet uses solid heat melting treatment.
The typical alloy of the 7000 series is 7075. The hardness of 7075 aluminum is unmatched by many other series of aluminum. The performance of 7000 aluminum is very close to that of the 2000 series. Not commonly used in life, after all, the price of 7075 aluminum sheet is relatively high.
