What is the difference between 1 series aluminum sheet, 3 series aluminum sheet and 5 series aluminum sheet? What are the uses of common aluminum sheet series?

According to the naming of aluminum sheet grades in the national standard, aluminum sheets can be roughly divided into 8 groups. According to the national standard "Representation of Deformed Aluminum and Aluminum Alloy Grades (GB/T 16474-2011)", four characters should be used in the designation of the grades, four characters The first, third and fourth digits of the system grades are Arabic numerals, and the second digits are English capital letters. The first digit of the grade represents the group of aluminum and aluminum alloy, and the second letter of the grade represents the original pure aluminum or aluminum alloy. In the case of modification, the last two digits are used to identify different aluminum alloys in the same group or to indicate the purity of aluminum.

01, 1*** series, industrial pure aluminum, is a grade series with the highest aluminum content, the aluminum content is not less than 99.00%, and has good elongation, tensile strength, plasticity and corrosion resistance. The production process is relatively simple, and the production technology is relatively mature. Several have great advantages, but have lower strength and are susceptible to compressive deformation. Mainly used for signs, billboards, wall decoration, kitchen utensils, chemical equipment, electronic devices and other products that do not require high strength. It is a series commonly used in conventional industries. At present, the 1100, 1050 and 1060 series of aluminum sheets are widely used in the building decoration industry.

02, 2*** series is aluminum copper alloy aluminum sheet (Al-Cu), with copper as the main alloy element, its content is between 3-5%, has high hardness and good cutting performance, has a certain heat resistance, can be heat treated. The disadvantage is that the corrosion resistance is poor, and it is mainly used in industries and products that require high strength and high temperature resistance, such as aircraft structures, missile components, spacecraft parts, and ship bodies.

03, 3*** series are aluminum-manganese alloy aluminum sheets (Al-Mn), also known as anti-rust aluminum sheets, with manganese as the main alloying element, its content is between 1.0-1.5%, and its strength is higher than that of 1 series aluminum sheets. Good formability, weldability and corrosion resistance. It is mainly used in industries with high requirements for anti-corrosion and anti-rust such as building decoration industry, electronic manufacturing industry, automobile manufacturing industry, etc. It is an industrial anti-rust aluminum sheet with a wide range of domestic applications. 3003, 3004 and other series of aluminum sheets.

04, 4*** series are aluminum-silicon alloy aluminum sheets (Al-Si), with silicon as the main alloying element, its content is usually between 4.5-6.0%, with high strength, low melting point, good corrosion resistance, resistance to It has the characteristics of good grinding performance and small thermal expansion coefficient. Mainly used in welding materials, etc.

05, 5*** series are aluminum-magnesium alloy aluminum sheets (Al-Mg), with magnesium as the main alloying element, with good processing and forming properties, corrosion resistance, welding properties, etc. It is widely used in conventional industry. Because of its low density and lighter weight than other series of aluminum sheets, it is also commonly used in ship structures, aircraft fuel tanks, automobile fuel tanks, etc. At present, 5052 series aluminum sheets are more commonly used in the building decoration industry. In practical application, because its hardness is too strong, aluminum veneer Buddha carbon curtain wall generally uses 3 series aluminum sheet.

06, 6*** series are aluminum-magnesium-silicon alloy aluminum sheets (Al-Mg-Si), with magnesium and silicon as the main alloy elements, with medium strength, good corrosion resistance, good weldability and oxidation effect. It is mainly used in industries and products with high requirements for corrosion resistance and oxidation resistance.

07, 7*** series are aluminum-zinc alloy aluminum sheets (Al-Zn-Mg-Cu), with zinc as the main alloying element, belonging to superhard aluminum alloys with good mechanical properties, wear resistance and fatigue resistance. However, the corrosion resistance is poor, and it needs to be covered with aluminum or other protective treatments. Mainly used in aerospace equipment materials, but also widely used in various machinery, molds and other processing fields.

08, 8*** series belong to other series of aluminum sheets, with other alloys as the main alloy elements, most of which are used as aluminum foil, which can be used in bottle caps, radiators, etc., and belong to the less commonly used series.
