Recently, many customers in the purchase of aluminum sheet, due to the processing of products want to improve the use of material demand, so the choice of each series of aluminum sheet holds a wait-and-see state, here, I give you a detailed introduction to the characteristics of each series of aluminum sheet and application.
Features: industrial pure aluminum sheet, has good elongation and tensile strength, good plasticity, corrosion resistance, electrical and thermal conductivity, the production process is relatively single, the production technology is relatively mature, compared with other high-grade aluminum alloy has a huge advantage. Disadvantages are low strength, not heat treatment to strengthen, machinability is not good, not easy brazing, easy compression deformation.
Application: It is mainly used in products with low strength requirements, such as automobile heat insulation board, billboard, building appearance decoration, wall decoration, electrical lighting, heat exchanger, kitchenware, conductive materials, chemical equipment, electronic devices. Inland water vessel equipment, all kinds of containers (wine cans, pressure tanks, tea furnaces, etc.), instruments and meters, signs (equipment signs, highway signs, motor vehicle license sheets, etc.), hardware cooking utensils, machine parts with little force.
Common brands: 1050, 1050A, 1060, 1070, 1100
Features: Also known as duralumin, the main alloying element is copper. Has high strength and good machining performance, has certain heat resistance, heat treatment, the disadvantage is poor corrosion resistance.
Application: Mainly used in aircraft structure (such as skin, etc.), aerospace, weapons, engines, pistons, automobile body, ship hull and stress components.
Common brand: 2017, 2024, 2A12
Features: Also known as rust-proof aluminum sheet, the main alloying element is manganese. The strength is higher than that of industrial pure aluminum sheet, good formability, welding and corrosion resistance. Since it cannot be strengthened by heat treatment, cold processing is used to improve its mechanical properties.
Application: It is mainly used in the application scope of industrial pure aluminum sheet and other fields with higher hardness requirements. It is often used in kitchenware, food and chemical storage and transportation, heat sink, household appliances (such as air conditioning, refrigerator, washing machine, etc.) and other fields.
Common brand: 3003, 3004, 3014
4 series aluminum sheet
Features: Most aluminum alloys with silicon as the main alloying element can not be strengthened by heat treatment. The silicon content is usually between 4.5-6.0%. Low melting point, good melt fluidity, easy to fill, good corrosion resistance; It has good wear resistance and heat resistance.
Application: Mainly used in welding materials.
Common grade: 4343
Features: high-grade aluminum alloy sheet, the main alloy element is Mg. It has good machining performance, corrosion resistance, welding performance, fatigue strength and moderate static strength. Not heat treatment, but the surface can be polished, relatively beautiful. Resistant to Marine climate.
Application: Mainly used in building decoration, pressure vessel, ship structure and offshore facilities, aircraft fuel tank, automobile fuel tank, automobile gas storage cylinder, container and so on.
Common brand: 5052, 5083, 5754, 5182
Features: The main alloying elements are magnesium and silicon, with moderate strength, good corrosion resistance, weldability, oxidation effect.
Application: Mainly used in construction, ships, rail vehicles, electronics, electrical electronics, consumer durables and other fields.
Common brand: 6061, 6063, 6082
Features: Super hard aluminum alloy series, the main alloy elements for zinc, magnesium, copper. Representing the grade 7050 and 7075, the deformed aluminum alloy sheet with excellent heat treatment effect and super high strength has good plasticity after solid melting treatment, and has good mechanical properties, wear resistance and fatigue resistance. Disadvantages are poor welding performance, stress corrosion cracking tendency, need to be covered by aluminum or other protective treatment.
Application: Mainly used in aerospace equipment of the first choice of materials, but also widely used in a variety of machinery, mold and other processing fields.
Common brand: 7075, 7050
8 series aluminum sheet
Features: Belongs to aluminum-lithium alloy, the main component is lithium, because lithium is the lightest metal in nature, aluminum sheet after adding lithium element, can ensure the strength of aluminum sheet at the same time, effectively reduce the proportion of aluminum sheet.
Application: to do bottle cap as the main function of aluminum sheet, also used in radiator, most of the application for aluminum foil.
Common brand: 8011, 8011A
