Features of 7475 aluminum sheet plate
High strength: 7475 aluminum plate is a high-strength aluminum alloy, and its tensile strength can reach 500-600MPa, or even higher, which is much higher than ordinary aluminum alloys.
Good corrosion resistance: 7475 aluminum alloy plate has good corrosion resistance by adding other alloy elements, and can resist corrosion in different environments, such as seawater, acid rain, etc.
Good machinability: 7475 aluminum sheet can be easily processed, formed and welded to meet the needs of different application scenarios.
Good wear resistance: 7475 aluminum plate has high surface hardness and excellent wear resistance, and performs well in high stress and high friction environments.
Good high-temperature performance: 7475 aluminum alloy sheet performs well in high-temperature environments, has high thermal stability, and is not easy to deform or lose strength.
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.
