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
