Aviation aluminum alloy is an aluminum alloy material used to manufacture aircraft. It has the characteristics of light weight, high strength, and high corrosion resistance. The following are some commonly used grades of aviation aluminum alloys and their main properties:
7075 aluminum alloy: This material has high strength, fatigue resistance and corrosion resistance, and is widely used in aircraft frames and stressed structural parts. It contains a large amount of zinc and has excellent strength and hardness after heat treatment.
7050 aluminum alloy: This material is an ultra-high-strength aluminum alloy used to manufacture aerospace structural parts that are subject to large forces, such as wings and fuselages. It contains zinc and magnesium elements and undergoes solution treatment and aging treatment to obtain high strength and good corrosion resistance.
7150 aluminum alloy: This material is a high-strength aluminum alloy used to manufacture stress-bearing structural parts of aircraft. It contains magnesium and small amounts of zinc and is heat treated to provide excellent strength and hardness.
2024 Aluminum Alloy: This material is a hard aluminum alloy used to manufacture aerospace structural parts that require high strength and fatigue resistance. It contains aluminum, copper and a small amount of magnesium and has excellent strength and hardness after heat treatment.
2017 Aluminum Alloy: This material is an aluminum alloy with medium strength and good plasticity, used to manufacture aerospace structural parts with less stress. It contains aluminum, copper and a small amount of magnesium, and has good overall properties after heat treatment.
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.
