What is aluminum plate, the thickness range of aluminum plate

Aluminum plate refers to aluminum materials with a thickness of more than 0.2mm to less than 500mm, a width of more than 200mm, and a length of less than 16m called aluminum sheets or aluminum sheets. With the progress of large equipment, there are many aluminum plates with a maximum width of 600mm).

Aluminum plate refers to a rectangular plate rolled and processed from aluminum ingots. It is divided into pure aluminum plate, alloy aluminum plate, thin aluminum plate, medium and thick aluminum plate, and patterned aluminum plate.

Aluminum sheets are usually divided into the following two categories:

1. According to the alloy composition is divided into:
High-purity aluminum plate (rolled from high-purity aluminum with a content of more than 99.9)
Pure aluminum plate (the 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. series)
Clad aluminum plate or welded plate (special purpose aluminum plate material is obtained by means of compounding various materials)
Aluminum-clad aluminum sheet (the outer side of the aluminum sheet is covered with thin aluminum sheet for special purposes)

2. According to thickness: (unit mm)
Sheet (aluminum sheet) 0.15-2.0
Conventional sheet (aluminum sheet) 2.0-6.0
Aluminum plate 6.0-25.0
Thick plate (aluminum plate) 25-200

The use of aluminum plate
1. Lighting 2. Solar reflector 3. Building exterior 4. Interior decoration: ceiling, wall, etc. 5. Furniture, cabinets 6, elevators 7, signs, nameplates, bags Photo 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. Mould manufacturing 14. Chemical/insulation pipeline coating. 15. High-quality ship board

Classification of aluminum sheets
The grades in the aluminum alloy are representative. The following is an example of the grade of 7075T651 aluminum plate. The first 7 represents the group of aluminum and aluminum alloys - aluminum-zinc-magnesium alloys. Aluminum and aluminum alloy groups are divided into nine categories. Among them, aluminum and aluminum alloys of 1, 3, 5, 6, and 7 series are the main ones, and 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 alloys
The fourth category: 4 series: aluminum silicon alloy
The fifth category: 5 series: aluminum-magnesium alloys
The sixth category: 6 series: aluminum magnesium silicon alloy
The seventh category: 7 series: aluminum-zinc-magnesium-copper alloys
The eighth category: 8 series: other alloys
Class 9: Series 9: Spare Alloys
