7XXX series aluminum roll alloy is the common alloy, which includes the zinc and magnesium elements. High strength aluminum roll alloy of 7xxx series is 7075 aluminum roll alloy. But 7075 aluminum roll alloy can not be welded, and its corrosion resistance is very poor, which is widely used in a lot of cutting parts with CNC. A little magnesium alloy which is putting into the 7075 aluminum roll alloy can make the material heat treatment, to reach very high strength. This series of 7xxx aluminum roll are generally added a small amount of copper, chromium and other alloys. 7075 aluminum roll alloy is especially the top grade with highest strength, which is suitable for aircraft frame and high strength parts.

The Features of 7075 Aluminum Roll Alloy:

1. High strength heat treatable alloy.

2. Good mechanical properties.

3. Good usability.

4., Easy to process and good wear resistance.

5., Corrosion resistance and good oxidation resistance.

7075 Aluminum Roll Alloy Chemical Composition:

Zinc is the main alloying element in 7075 aluminum roll alloy. Adding some magnesium to the aluminum roll alloy which is containing 3%-7.5% zinc can form a MgZn2 with remarkable strengthening effect, so that the heat treatment effect of the alloy is much better than that of Al Zn alloy.

1.Through increasing the content of zinc and magnesium in the alloy, the tensile strength will be further improved, but the ability to resist stress corrosion and peel resistance will be decreased.

By heat treatment, 7075 aluminum roll alloy can reach very high strength. 7075 aluminum roll
