Overview of 7075 Aluminum Sheet and Plate
7075 aluminum sheet belongs to the Al-Zn-Mg-Cu super-duralumin series. It is a cold-worked, heat-treatable alloy featuring extremely high strength and hardness, far exceeding that of mild steel. Due to these outstanding mechanical properties, 7075 T6 aluminum plate is widely recognized as a premium material for high-stress structural applications.
Common supply tempers include:
7075 T6 aluminum sheet/plate
7075 O aluminum sheet
7075 T62 aluminum sheet
7075 T73 aluminum sheet
Applications of 7075 Aluminum Sheet
7075 aluminum sheet is extensively used in the manufacture of aircraft structures and other high-stress components requiring high strength and good corrosion resistance. Typical applications include upper and lower wing skins, trusses, frames, and spacers.
In addition, 7075 aluminum sheet is widely applied in high-end mobile phone housings, precision mechanical parts, golf components, and other products where lightweight and high strength are essential.

Mechanical Strength of 7075 Aluminum Plate
Depending on the heat treatment condition, 7075 aluminum plate can achieve a yield strength of up to 500 MPa and an ultimate tensile strength of approximately 560 MPa, making it one of the strongest aluminum alloys available.
Corrosion Resistance of 7075 Aluminum Plate
All tempers of 7075 aluminum plate have been evaluated for atmospheric corrosion, stress corrosion cracking, and exfoliation corrosion. Overaged tempers in the T7xxx series provide significantly improved corrosion resistance and stress corrosion cracking resistance compared with high-strength T6 tempers.
For applications requiring exceptional corrosion resistance-such as aircraft skins-Alclad 7075 aluminum sheet is strongly recommended.
Characteristics of 7075 Aluminum Plate by Temper
7075-T651 aluminum plate offers excellent fatigue strength, good machinability, resistance to spot welding, and reliable corrosion performance.
7075-T7351 aluminum plate provides outstanding resistance to stress corrosion cracking and is often used as a replacement for 2xxx series alloys in critical aerospace applications.
7075-T7651 aluminum plate is regarded as having superior exfoliation resistance and overall corrosion resistance.
Typical Applications of 7075 Aluminum Plate
Alclad 7075 aluminum sheet is commonly used for aircraft skin applications. Thick 7075 aluminum plates, including plates around 4 inches thick, are primarily used for aircraft structural components and other highly stressed aerospace parts.
