The brand names in aluminum alloy are representative. Let's take the example of 7075T651 aluminum plate as an example.
The first 7 represents aluminum and aluminum alloy group aluminum zinc magnesium alloy. Aluminum and aluminum alloy groups are divided into nine categories. One of the 1, 3, 5, 6, 7 series of aluminum and aluminum alloy is the main, and the other series are less used in practical use. First category: 1 Series: second types of industrial pure aluminum: 2 Series: third types of aluminum copper alloy alloys: 3 Series: fourth aluminum alloy alloy: 4 series: fifth of aluminum and silicon alloy alloy, 5 series, sixth aluminum and magnesium alloy, 6: aluminum magnesium silicon alloy seventh: 7, aluminum, zinc, magnesium and copper alloys; other alloy Alloy
