7075 Aluminum Plate and Sheet
Alloy 7075 has been the standard workhorse 7XXX series alloy within the aerospace industry. Zinc is the primary alloying element in 7075 and was the first successful Al-Zn-Mg-Cu high strength alloy using the beneficial effects of the alloying addition of chromium to develop good stress-corrosion cracking resistance in sheet products. 7075 Aluminum has a lower level of corrosion resistance and has no weldability, i.e. it is not weldable. This particular kind of alloy is known for its level of fatigue strength, however, it is only average when it comes to machinability.
7075 Aluminum Applications
7075 Aluminum is one of the highest strength aluminum alloys made for the industrial and consumer markets. Although other 7XXX alloys have since been developed, Alloy 7075 remains the baseline with a good balance of properties required for aerospace applications. In terms of application, it is perfect for parts that have areas that are highly stressed. These specific strength properties are ideal for the construction of military grade rifles, plastic industry molds, bicycle part and equipment as well as aircraft structures.
7075 T651 Aluminum
7075 T651 Aluminum is also available and is best suited for aviation and aerospace applications. Ultimately, if strength is what you need, this particular tempered alloy also has higher tensile strength.
