EN AW 7075 

ALZn5, 5MgCu-3.4365 

High strength Aluminum 

Mainly used for aviation, mold making, 

Mechanical engineering, precision component

EN AW 7075 (AlZn5, 5MgCu-3.4365) is a very high strength aerospace aluminum and is commonly used in applications where the strength of the material is critical and where the need for good corrosion resistance is not important. Offering superior stress corrosion resistance, 7075 provides very high yield and tensile strength which is dictated by the particular chosen temper. We stock AW 7075 in plate, flats, bars.
