    CNC machining
This grade of aluminum is also known as aircraft or aerospace aluminum due to its prevalent application in these fields. The primary constituent of 7075 alloys is zinc. Its exceptional strength distinguishes it from other aluminum alloys, rivaling the strength of many steels. While it offers a favorable blend of properties for numerous applications, 7075-T6 exhibits lower corrosion resistance compared to other aluminum alloys, but possesses very good machinability.
