Specific Applications of 7175 Aluminum Profiles in the Aerospace Field
1. Aerospace Structural Components
7175 aluminum profiles are widely used in the primary structural components of aircraft, such as wing frames, fuselage structures, and tail assemblies. These components must meet high strength and stiffness requirements to ensure flight safety and performance. The tensile and compressive strength of 7175 aluminum profiles make them ideal materials for meeting these stringent requirements. Additionally, the corrosion resistance of this alloy helps extend the lifespan of the aircraft.
2. Wing Components
In wing design, 7175 aluminum profiles are used to manufacture critical components such as spars and ribs. Spars are essential parts that support the wing structure and must possess extremely high strength and stiffness to resist various loads during flight. Ribs provide the shape and aerodynamic performance of the wing. The lightweight characteristics of 7175 aluminum profiles can reduce the overall weight of the wing, thereby improving the aircraft's fuel efficiency and flight performance.
3. Landing Gear
The landing gear is a key component of the aircraft that withstands immense impact forces during landing. Due to its excellent strength and toughness, 7175 aluminum profiles are often used in certain components of the landing gear, such as support arms and connectors.
