7175 Aerospace Aluminum Forgings

7175 aerospace aluminum forgings are a type of high-strength aluminum alloy material primarily used in the aerospace field. The 7175 alloy belongs to the aluminum-zinc-magnesium alloy series, featuring excellent mechanical properties and corrosion resistance, making it suitable for manufacturing structural components and parts of aircraft.

The 7175 alloy is typically heat-treated (such as in the T6 condition) to enhance its strength and hardness. During the forging process, the material is heated to a certain temperature and then deformed using mechanical force to achieve the desired shape and properties.

When using 7175 aluminum alloy, it is important to consider its strength degradation in high-temperature environments and its corrosion potential in certain chemical environments. Therefore, careful material selection and treatment should be conducted during design and application.

Characteristics of 7175 Aerospace Aluminum Forgings

• High Strength: The 7175 alloy exhibits extremely high tensile strength after heat treatment, making it suitable for high-load applications.
• Toughness: It has a good balance between strength and toughness, though its toughness may be lower compared to other aluminum alloys.
• Good Corrosion Resistance: Although aluminum-zinc alloys generally have relatively poor corrosion resistance, suitable surface treatments can enhance their corrosion resistance.
• Machinability: The 7175 alloy demonstrates good machinability during forging and processing, making it suitable for manufacturing complex shapes.
• Lightweight: The low density of aluminum alloys helps reduce the overall weight of the aircraft, improving fuel efficiency.
