Description
7075 aluminum sheet is a high-strength aerospace aluminum alloy that is commonly used in the manufacture of aircraft and other high-stress applications.
It has excellent strength-to-weight ratio and is resistant to stress corrosion cracking. The alloy is available in various thicknesses and sizes, and can be easily machined and formed. It is also heat treatable, which allows for further strengthening of the material.
7075 aluminum sheet is typically used in the construction of aircraft wings, fuselage frames, and other structural components. It is also used in the manufacturing of high-performance sporting equipment, such as bicycle frames and rock climbing gear.
Aluminum Sheet / Plate 7075-T6/T651 is normally used for aerospace, military, and automotive applications. 7075 aluminum is the strongest aluminum, with the strength of many steels, while retaining aluminum’s lightweight qualities and corrosion resistance.

Aluminum 7075 is a member of the 7000 series, which has zinc as its main alloying component and is well known for its extraordinarily high strength. Tempering treatment can then further enhance its high mechanical strength. This property makes alloy 7075 very popular in the aerospace and defense industries.

Its strength is comparable to that of many types of steel, but it has a much lower density. The alloy is an excellent substitute to steel in high-stress applications. It also excels in withstanding fatigue stress, rendering it very reliable, a quality much sought after in the industries mentioned above.
Alloy 7075 offers only average corrosion resistance, an outcome of the small amount of copper included in its chemical composition. It also features reasonable machinability and poor forming and weldability. Another drawback of this alloy is that it has a comparatively high-cost relative to other aluminum alloys due to its exceptionally high strength.
