7075 T6 T651 Aluminum Tube Pipe

Product Detail

Alloy 7075 aluminum 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 (>400 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.
