7068 aluminum alloy is a new high-performance aluminum alloy developed by Kaiser Aluminum Company in the United States. The typical yield strength reaches 700 MPa, which is 15% to 20% higher than 7075 alloy. The high temperature performance is better than 7075 aircraft aluminum plate. The corrosion resistance is equivalent to that of 7075 alloy. Its comprehensive performance is very good.

Its main tempers are O, T6, T651, T73 and T76. 7068-T6 aluminum sheet has the highest static strength, the lowest plastic toughness, poor fatigue performance, and is sensitive to stress corrosion cracking, and the toughness decreases with the decrease of temperature, so it is not used for low temperature working parts.

The T73 temper has the lowest strength, but has higher fracture toughness and excellent resistance to stress corrosion cracking and erosion. The performance of the T76 temper is between T6 and T73. Compared with the T6 temper, the strength of T76 is low but the stress corrosion resistance is better. Compared with the T73 temper, the strength of T76 is high but the stress corrosion resistance is a little lower.

The Applications of 7068 Aircraft Aluminum Alloy

In the early time, 7068 aluminum sheet was used for making ordnance. At present, 7068 aluminum has been a main alloy in the aerospace and automotive industries, medical devices, such as prosthetic limbs, as well as recreational products like bicycles and mountain-climbing equipment.
