7075 aircraft aluminum is one of the highest strength aluminum alloys available, on par with several types of steel. Its strength-to-weight ratio is excellent, and it is ideally used for highly stressed parts. Because of its strength threshold, 7075 aluminum is often used for those parts of the airplane aluminum that experience high-stress levels like the wing spar. Available in the alclad form to provide corrosion resistance with the over-all high strength being only moderately affected.
Aluminium Alloy 7075 offers the highest strength of the common screw machine alloys. The superior stress corrosion resistance of T173 and T7351 tempers makes aluminum alloy 7075 a logical replacement for 2024, 2014 and 2017 aluminum in many of the most critical applications. The T6 and T651 tempers have fair machinability. Alloy 7075 is heavily utilized by the aircraft and ordnance industries because of its superior strength.
