7475 T7351 aviation aluminum Plate is a high-strength, high-hardness aviation-specific aluminum material. It is mainly used to manufacture key parts such as aircraft frames, skins, and landing gears.
7475 T7351 Aviation aluminum Plate has good corrosion resistance, high fatigue resistance and good plastic toughness, and can maintain good performance under extreme temperature and pressure conditions. The application of this aluminum material helps improve the safety and reliability of aircraft and extend their service life.
7475-T7351 aluminum plate is an American deformed aluminum alloy plate suitable for plate and plate applications requiring high strength, excellent fracture toughness and resistance to fatigue crack propagation.
Typical fracture toughness values for Alloy 7475 plate are approximately 40% higher than Alloy 7075 in the same condition. The durability and fatigue properties of Alloy 7475 are equal to and in some cases better than many current high-strength aerospace alloys such as 7075, 7050 and 2024.
