7475 aerospace aluminum plate

Uses of 7475 aluminum sheet plate

7475 aluminum alloy is mainly used to manufacture structural parts with high strength, medium fatigue strength and high fracture toughness, such as wing skin, fuselage skin, bulkhead, etc. The use of 7475 aluminum alloy can improve the safety, reliability and use of aircraft life.

Since the 7475 aluminum alloy is a high-strength aluminum alloy at room temperature, the strength of the alloy decreases with the increase of the use temperature, and its long-term use temperature does not exceed 125°C.

The alloy has good technological plasticity and superplasticity, and thin plate parts with complex shapes can be formed by superplasticizing thin plates with ultrafine grain structure. The sheet in the annealed and solution heat treated (W) temper has good formability.
