1 series aluminum plate
Features: Industrial pure aluminum plate has good elongation and tensile strength, good plasticity, corrosion resistance, electrical conductivity and thermal conductivity, the production process is relatively simple, the production technology is relatively mature, and the price has a huge advantage over other high-grade aluminum alloys. The disadvantage is that the strength is low, it cannot be strengthened by heat treatment, the machinability is not good, it is not easy to braze, and it is easy to deform under pressure.
Application: Mainly used in products that do not require high strength, such as automobile heat insulation boards, billboards, architectural exterior decoration, wall decoration, electrical lighting, heat exchangers, kitchen utensils, electrical conductor materials, chemical equipment, electronic devices, inland watercraft Equipment, various containers (wine cans, pressure tanks, tea stoves, etc.), instruments, signs (equipment signs, road signs, motor vehicle license plates, etc.), hardware cookers, machine parts with little stress.
Common grades: 1050, 1050A, 1060, 1070, 1100
2 series aluminum plate
Features: Also known as hard aluminum, the main alloying element is copper. It has high strength and good machinability, has certain heat resistance, and can be heat treated. The disadvantage is that it has poor corrosion resistance.
Application: Mainly used in aircraft structures (such as skins, etc.), aerospace, weapons, engines, pistons, automobile bodies, ship hulls and stressed components, etc.
Common grades: 2017, 2024, 2A12
3 series aluminum plate
Features: Also known as anti-rust aluminum plate, the main alloying element is manganese. The strength is higher than industrial pure aluminum plate, and the formability, weldability and corrosion resistance are good. Since it cannot be strengthened by heat treatment, cold working is often used in the process to improve its mechanical properties.
Application: It is mainly used in the application range of industrial pure aluminum plates and other fields that require higher hardness. It is often used in various fields such as kitchen utensils, food and chemical storage and transportation, heat sinks, and home appliances (such as air conditioners, refrigerators, washing machines, etc.).
Common grades: 3003, 3004, 3014
4 series aluminum plate
Features: Most aluminum alloys with silicon as the main alloying element cannot be strengthened by heat treatment. Usually the silicon content is between 4.5-6.0%. Low melting point, good melt fluidity, easy feeding, good corrosion resistance; good wear resistance and heat resistance.
Application: Mainly used in welding materials, etc.
Common grades: 4343
5 series aluminum plate
Features: It is a high-grade aluminum alloy plate, the main alloying element is Mg. It has good processing and forming performance, corrosion resistance, welding performance, fatigue strength and medium static strength. It cannot be strengthened by heat treatment, but the surface can be polished, which is relatively beautiful. Resistant to marine climates.
Application: mostly used in architectural decoration, pressure vessels, ship structures and offshore facilities, aircraft fuel tanks, automobile fuel tanks, automobile gas storage tanks, containers, etc.
Common grades: 5052, 5083, 5754, 5182
6 series aluminum plate
Features: The main alloying elements are magnesium and silicon, with medium strength, good corrosion resistance, good weldability and oxidation effect.
Application: Mainly used in construction, ships, rail vehicles, electronics, electrical appliances and electronics, durable consumer goods and other fields.
Common grades: 6061, 6063, 6082
7 series aluminum plate
Features: superhard aluminum alloy series, the main alloying elements are zinc, magnesium and copper. Representative grades 7050 and 7075, with excellent heat treatment effect, super high strength deformed aluminum alloy plate, good plasticity after solution treatment, good mechanical properties, wear resistance and fatigue resistance. The disadvantage is that the welding performance is poor, there is a tendency of stress corrosion cracking, and it needs to be covered with aluminum or other protective treatments.
Application: It is mainly used as the preferred material for aerospace equipment, and is also widely used in various machinery, mold and other processing and manufacturing fields.
Common grades: 7075, 7050
8 series aluminum plate
Features: It belongs to aluminum-lithium alloy, the main component is lithium, because lithium is the lightest metal in nature, after adding lithium element to the aluminum plate, it can effectively reduce the specific gravity of the aluminum plate while ensuring the strength of the aluminum plate.
Application: The aluminum plate mainly used as a bottle cap is also used in radiators, most of which are aluminum foil.
Common grades: 8011, 8011A
