Aluminum plate refers to aluminum material with a thickness of 0.2mm or more to 500mm or less, a width of 200mm or more, and a length of 16m or less.It is called aluminum plate or aluminum sheet. With the progress of large equipment, there are more aluminum plates with the widest width of 600mm).
Aluminum plate refers to the rectangular plate made by rolling aluminum ingot, which is divided into pure aluminum plate, alloy aluminum plate, thin aluminum plate, medium-thick aluminum plate, and pattern aluminum plate.
Aluminum plates are usually divided into the following 2 categories:
1.According to alloy composition:
High-purity aluminum plate (rolled from high-purity aluminum with a content of 99.9 or more)
Pure aluminum plate (the composition is basically made of pure aluminum rolled)
Alloy aluminum plate (composed of aluminum and auxiliary alloys, usually aluminum-copper, aluminum-manganese, aluminum-silicon, aluminum-magnesium, etc.)
Composite aluminum plate or brazed plate (a special purpose aluminum plate material is obtained through a variety of material composite methods)
Aluminum-clad aluminum plate (the outer side of the aluminum plate is covered with a thin aluminum plate for special purposes)
2. Divided by thickness: (unit mm)
Aluminum sheet 0.15-2.0
Conventional board (aluminum sheet) 2.0-6.0
Aluminum plate 6.0-25.0
Aluminum plate 25-200
Super thick board above 200
Application:
1. Lighting 2. Solar reflective sheet 3. Building appearance 4. Interior decoration: ceiling, wall, etc. 5. Furniture, cabinets 6. Elevator 7. Signs, nameplates, luggage 8. Interior and exterior decoration of automobiles 9. Interior decorations: such as Frame 10, household appliances: refrigerators, microwave ovens, audio equipment, etc. 11. Aerospace and military aspects, such as China's large aircraft manufacturing, Shenzhou spacecraft series, satellites, etc. 12. Machining of mechanical parts. 13. Mold manufacturing. 14. Chemical/heat preservation pipe coating. 15. High-quality ship board
Classification
The grades of aluminum alloys are representative. The following will take the grades of 7075T651 aluminum plates 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. 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 alloy
The third category: 3 series: aluminum-manganese alloy
The fourth category: 4 series: aluminum-silicon alloy
The fifth category: 5 series: aluminum-magnesium alloy
The sixth category: 6 series: aluminum-magnesium-silicon alloy
The seventh category: 7 series: aluminum-zinc-magnesium-copper alloy
The eighth category: 8 series: other alloys
The ninth category: 9 series: spare alloy
chemical composition:
Aluminum Al: balance; silicon Si: 0.25; copper Cu: 0.10 ; magnesium Mg: 2.2～2.8; zinc Zn: 0.10; manganese Mn: 0.10; chromium Cr: 0.15～0.35; iron Fe: 0.40.
Tensile strength (σb): 170～305MPa
Conditional yield strength σ0.2 (MPa)≥65
Elastic modulus (E): 69.3～70.7Gpa
The annealing temperature is: 345°C.
The term
Brushed aluminum plate: The manufacturing process of repeatedly scraping the aluminum plate out of lines with sandpaper. The main process of the process is divided into three parts: de-esterification, sand mill, and water washing. In the aluminum sheet wire drawing process, the special coating technology after anodizing can make the surface of the aluminum sheet generate a coating layer containing the metal component, clearly showing every minute trace, so that the metal matte will appear in the fine hair. Silk luster.
Alumina plate: The aluminum plate is placed in the corresponding electrolyte (such as sulfuric acid, chromic acid, oxalic acid, etc.) as the anode, and electrolyzed under specific conditions and applied current. The aluminum plate of the anode is oxidized, and a thin layer of aluminum oxide is formed on the surface, the thickness of which is 5-20 microns, and the hard anodized film can reach 60-200 microns.
PS aluminum plate (advertising aluminum plate, also known as printed zinc plate, newspaper plate): that is, an aluminum plate with a printed pattern thickness of 025 or 03 on the back.
Mirror aluminum plate: refers to the aluminum plate that is processed by rolling, polishing and other methods to make the surface of the plate show a mirror effect.
Embossed aluminum plate can also be called aluminum embossed plate: it belongs to aluminum products that form various patterns on the surface after calendering on the basis of aluminum plate. It is widely used and mainly used in packaging, construction, curtain walls, etc.
