Common uses of aluminum panels include: lighting; solar reflectors; architectural decoration; interior decoration: ceilings, walls, etc.; furniture, cabinets; elevators; signs, nameplates, luggage; interior and exterior decoration of automobiles; interior decorations: such as photo frames, aluminum panels , Reliefs, etc.; household appliances: refrigerators, microwave ovens, audio equipment, etc.; aerospace and military aspects, such as China's large aircraft manufacturing, Shenzhou spacecraft series, satellites, etc.; mechanical parts processing; mold manufacturing; chemical, thermal insulation pipe coating;
Aluminum plates are usually divided into the following two categories: 1. According to thickness: (unit mm) thin plate (aluminum sheet) 0.15-2.0 conventional plate (aluminum sheet) 2.0-6.0 medium plate (aluminum plate) 6.0-25.0 thick plate (aluminum plate) 25-200 ultra-thick plate above 200 2. According to the alloy composition, it is divided into: high-purity aluminum plate (rolled from high-purity aluminum with a content of 99.9 or more) pure aluminum plate (composition is basically rolled from pure aluminum)
Alloy aluminum plate (composed of aluminum and auxiliary alloys, usually aluminum-copper, aluminum-manganese, aluminum-silicon, aluminum-magnesium, etc.), composite aluminum plate or welded plate (special-purpose aluminum plate material obtained by a variety of material composite methods) clad aluminum plate (The outer side of the aluminum plate is covered with a thin aluminum plate for special purposes) The grades of aluminum alloys are representative. The following will take the 7075 T651 aluminum plate grades as an example. The first 7 represents the aluminum and aluminum alloy group-aluminum-zinc-magnesium alloy.
Aluminum and aluminum alloy groups are divided into nine categories. Among them, aluminum and aluminum alloys of series 1, 3, 5, 6, and 7 are the main ones. Among them, series 1 and 3 are the most commonly used. Other series are less likely to be used in actual use. The first category: 1 series: industrial pure aluminum, the second category: 2 series: aluminum-copper series alloys, the third category: 3 series: aluminum-manganese series alloys, the fourth series: 4 series: aluminum-silicon series alloys, the fifth series: 5 series: Aluminum-magnesium-based alloys Category 6: 6-series: Aluminum-magnesium-silicon-based alloys Category 7: 7-series: aluminum-zinc-magnesium-copper alloys Category 8: 8-series: other alloys
Technical quality requirements of aluminum plates:
1. The most basic point is that the surface of the sheet must be clean, no cracks and other oxide impurities are allowed.
2. Due to the imperfection of the process, the surface of the plate is allowed to have defects such as depression, scratches or roll indentation, but the depth must not exceed the allowable negative deviation of the plate, and it must be re-made if the deviation exceeds the deviation value.
Third, the process package aluminum thick plate allows the peeling part of the coating layer and the air bubbles in the coating layer.
4. Under normal circumstances, the surface of the sheet is allowed to repair the defects within the thickness difference. Five, some other requirements are mainly drawn up with the demanding suppliers and suppliers, and then the process is changed.
