7075 aluminum sheet is a high-strength aerospace-grade aluminum alloy that is widely used in the aviation and aerospace industries. It is known for its excellent strength-to-weight ratio, good corrosion resistance, and high fatigue strength. The alloy is composed of zinc as the primary alloying element, with smaller amounts of magnesium, copper, and chromium.
The 7075 aluminum sheet is available in a variety of thicknesses, widths, and lengths, making it suitable for a wide range of applications. It can be easily machined, welded, and formed, making it ideal for use in the production of aircraft parts, structural components, and high-performance equipment.
7075 aluminum sheet is available in a range of tempers, each with its own unique characteristics. The most common tempers for 7075 aluminum sheet are T6, T651, and T7351.
T6 Temper: The T6 temper is the most common temper for 7075 aluminum sheet. It offers excellent strength, good fatigue resistance, and good machinability. The T6 temper is achieved by solution heat treatment and then artificially aging the sheet. This temper is suitable for general-purpose applications, including structural components, aircraft parts, and high-performance equipment.
T651 Temper: The T651 temper is heat-treated and stretched to reduce internal stress and improve dimensional stability. This temper offers improved resistance to stress corrosion cracking. The T651 temper is suitable for applications that require high strength and dimensional stability, such as aircraft parts, structural components, and high-performance equipment.
T7351 Temper: The T7351 temper is a stress-relieved version of T6 that offers improved resistance to stress corrosion cracking. This temper is achieved by applying stress relief to the sheet after solution heat treatment and artificial aging. The T7351 temper is suitable for applications that require improved resistance to stress corrosion cracking, such as aircraft parts and structural components.
The 7075 aluminum sheet is suitable for a wide range of applications, including:
- Aircraft parts: The sheet is commonly used in the production of aircraft parts, including wings, fuselage frames, and landing gear components.
- Structural components: It is also used in the production of high-strength structural components for the construction industry.
- High-performance equipment: The sheet is used in the manufacturing of high-performance bicycles, sporting equipment, and automotive parts.
In terms of processing, 7075 aluminum sheet can be easily machined, welded, and formed. It can be cut to size using a variety of cutting methods, including sawing, shearing, and waterjet cutting. It can also be formed into complex shapes using a variety of forming methods, including bending, stamping, and roll forming. These processing capabilities make it possible to produce a wide range of parts and components with the sheet.
