,

Core Characteristics

,

Exceptional strength-to-weight ratio: Delivers strength comparable to low-carbon steel while being only one-third of its weight.

,

Superior machinability: Designed for ease of cutting, milling, drilling, and tapping, ensuring consistent processing performance for all your manufacturing needs.

,

Limited formability: Offers lower ductility than alternatives like 6082 or 3104, making it suitable for simple bending rather than complex forming tasks.

,

Corrosion resistance: While it can be susceptible to stress corrosion cracking in severe environments, the T73 temper significantly enhances corrosion resistance.

,

Anodizing features: Develops a dense, uniform oxide film that supports coloring for both protective and aesthetic applications.

Key Mechanical Properties

,

Tensile strength: ≥ 540MPa (subject to slight variations by temper, with T6 temper being the most representative).

,

Yield strength: ≥ 480MPa (providing excellent load-bearing capabilities for structural applications).

,

Elongation: ≥ 11% (achieving a balance between ultra-high strength and moderate ductility).

,

Common tempers: T6 (solution heat-treated + artificial aging, widely used), T651 (stressed-relieved after T6 for improved dimensional stability), T73 (ideal for harsh environments due to enhanced corrosion resistance).

Frequently Asked Questions (FAQ)

  • What is 7075 aluminum sheet and what makes it special?
    7075 aluminum sheet is a high-strength aluminum alloy primarily composed of zinc (5.1–6.1%), magnesium (2.1–2.9%), and copper (1.2–2.0%). It is one of the strongest aluminum alloys available, offering an exceptional strength-to-weight ratio, making it ideal for aerospace, defense, and high-performance industrial applications.
  • What are the most common temper designations for 7075 aluminum?
    The most widely used tempers for 7075 aluminum are T6 and T651, which provide the highest strength through solution heat treatment and artificial aging. Other available tempers include T3, T4, T73, T451, T351, T851, and T7351, each offering different balances of strength, corrosion resistance, and machinability.
  • What thickness and size range is available for 7075 aluminum sheet/plate?
    7075 aluminum sheet and plate is available in thicknesses ranging from 1.0 mm to 600 mm, with diameters from 50 mm to 1,200 mm. Custom dimensions can be produced via DC (Direct Chill) casting to meet specific project requirements.
  • Which industries use 7075 aluminum sheet the most?
    7075 aluminum is heavily used in aerospace (aircraft fuselage frames, wing spars, landing gear), defense (military armor plates, drone frames), sports equipment (bicycle frames, golf shafts), industrial machinery (mold bases, precision tooling), and electronics (high-strength instrument casings and battery brackets).
  • Who are the leading manufacturers and buyers of 7075 aluminum?
    Major global producers include Alcoa, Kaiser Aluminum, Novelis, Constellium, and Norsk Hydro, along with Chinese manufacturers such as Chalco. Key buyers include Boeing, Airbus, Lockheed Martin, SpaceX, General Dynamics, and Northrop Grumman, as well as manufacturers in the automotive, mold-making, and precision machinery sectors.
  • How does 7075 aluminum compare to other aluminum alloys like 6061?
    7075 aluminum offers significantly higher tensile strength than 6061 aluminum — typically around 572 MPa (T6) versus 310 MPa for 6061-T6. However, 6061 provides better corrosion resistance, weldability, and formability. 7075 is preferred when maximum strength is the priority, while 6061 is chosen for general-purpose structural applications requiring easier fabrication.
