Anti corrosion and thermal insulation aluminum roll aluminum sheet

Aluminum sheet refers to the 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. Aluminum materials with a thickness of less than 0.2mm are aluminum materials, and aluminum materials with a width of less than 200mm are row materials or strips (of course, with the progress of large equipment, there are more aluminum plates with a maximum width of 600mm).

classification

The grade of aluminum alloy is representative. The following is an example of 7075T651 aluminum plate grade. 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 mainly used, and other series are seldom used in actual use.

Class I: Series 1: industrial pure aluminum

Class II: Series 2: Aluminum copper alloy

Class III: Series 3: Aluminum manganese alloy

Class IV: Series 4: Aluminum silicon alloy

Class V: Series 5: Aluminum magnesium alloys

Category VI: Series 6: Al Mg Si alloys

Class 7: Series 7: Al Zn Mg Cu alloys

Class VIII: Series 8: Other alloys

Class IX: Series 9: Spare alloy
