Alternative names
AlZn5,5MgCu, 3.4365
Process compatibility
CNC machining
This grade of aluminum is also know as aircraft or aerospace aluminum due its most common application. The dominant element of 7075 alloys is zinc. Its high strength makes is stand out from the other aluminium alloys and be comparable to the strength of many steels. Even though it has convinent combination of properties for many applications, 7075-T6 compared to other aluminium alloys has lower corrosion resistance, but very good machinability
