Factory Supply 5083 Marine Aluminum Plate - Aluminum 7075 T7451 Aircraft High Strength 7075 Plate – Miandi
Factory Supply 5083 Marine Aluminum Plate - Aluminum 7075 T7451 Aircraft High Strength 7075 Plate – Miandi Detail:
Alloy 7075 aluminum plates are the outstanding member of the 7xxx series and remains the baseline among the highest strength alloys available. Zinc is the primary alloying element giving it strength comparable to steel. Temper T651 possesses good fatigue strength, fair machinability, resistance welding and corrosion resistance ratings. Alloy 7075 in temper T7x51 has superior stress corrosion resistance and replaces the 2xxx alloy in the most critical applications.
7075 aluminum alloy is one of the strongest aluminum alloys available, making it valuable in high-stress situations. Its high yield strength (>500 MPa) and its low density make the material a fit for applications such as aircraft parts or parts subject to heavy wear. While it is less corrosion resistant than other alloys (such as 5083 aluminum alloy, which is exceptionally resistant to corrosion), its strength more than justifies the downsides.
The superior stress corrosion resistance of the T73 and T7351 tempers makes alloy 7075 a logical replacement for 2024, 2014 and 2017 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.
