7075 Aerospace Aluminum Bar Rod

7075 aluminum belongs to the 7000 series and is one of the strongest aluminum alloys available. Its primary alloying element is zinc, along with small amounts of magnesium and copper. Due to its high strength-to-weight ratio and good fatigue resistance, it is commonly used in aerospace and high-performance applications.

7075 aerospace aluminum is a high-strength, heat-treatable aluminum alloy known for its excellent mechanical properties and corrosion resistance. It is typically used in aerospace applications, as well as in the military and automotive industries.

To improve corrosion resistance, 7075 aluminum is often anodized or coated with a chromate conversion layer. This makes it more suitable for outdoor applications or harsh environments.

Features of 7075 Aerospace Aluminum Bar Rod

  • 1. High strength: 7075 aluminum is one of the strongest aluminum alloys, with a tensile strength range of 572 to 616 MPa, depending on the tempering condition.
  • 2. Fatigue resistance: It has good fatigue resistance, making it suitable for applications that endure cyclic loads.
  • 3. Machinability: The alloy has good machinability, but due to its high strength, it is more difficult to machine compared to other aluminum alloys.
  • 4. Corrosion resistance: While its corrosion resistance is better than some other high-strength alloys, it is still susceptible to corrosion and may require protective coatings in harsh environments.
  • 5. Weldability: 7075 is generally not weldable, as welding can significantly reduce its strength. Alternative joining methods such as riveting or adhesives are typically used.

Sizes and Forms of 7075 Aerospace Aluminum Bar Rod Available

7075 aluminum bars and rods are typically available in various diameters, lengths, and shapes (such as round, square, or flat).

T651: Similar to T6, this condition involves stretching to relieve stress, which helps reduce internal stress and improve dimensional stability.

The T6 condition is achieved through solution heat treatment followed by artificial aging. This increases strength but slightly reduces ductility.

7075 T6 Aluminum Bar Rod

7075 T6 aluminum is a high-strength alloy known for its excellent mechanical properties. The "T6" designation indicates that the material has been solution heat-treated and artificially aged, resulting in enhanced strength and hardness. This type of bar rod is commonly used in structural applications, aerospace components, and high-stress environments due to its superior strength-to-weight ratio.

7075 T651 Aluminum Bar Rod

Similar to the T6 designation, the "T651" indicates that the aluminum has gone through a solution heat treatment and is then stress-relieved by stretching to eliminate internal stresses. This process improves the dimensional stability and mechanical properties of the material. The 7075 T651 aluminum bar rod is ideal for applications requiring high strength, such as aerospace, military, and automotive components.

7075 Aerospace Al Extruded Bar

This refers to 7075 aluminum that has been extruded into bar form, specifically designed for aerospace applications. The extrusion process involves forcing the aluminum through a die to create a specific cross-sectional shape. This results in a product with excellent mechanical properties, uniformity, and surface finish, making it suitable for structural components in aircraft and other aerospace vehicles.

7075 Aerospace Aluminum Forged Bar

This type of bar is made from 7075 aluminum that has been forged, a process that involves shaping the metal through compressive forces. Forging enhances the strength and toughness of the aluminum, making it ideal for high-stress applications in aerospace. The resulting bar has a fine-grained structure, which provides improved mechanical properties over cast materials.

7075 Aerospace Aluminum Round Bar

A round bar made from 7075 aluminum, this product is used in various aerospace applications where round shapes are required. The round bar can be used for manufacturing components such as shafts, pins, and fittings. Its high strength and lightweight properties make it suitable for demanding environments.

7075 Aerospace Aluminum Square Bar

This square bar is also made from 7075 aluminum and is often used in applications where a square cross-section is necessary. It is commonly utilized for structural components, brackets, and frames in aerospace and other industries due to its excellent strength-to-weight ratio.

7075 Aerospace Aluminum Flat Bar

A flat bar made from 7075 aluminum, this product is often used in applications requiring flat surfaces, such as supports, brackets, and other structural components. The flat bar can be easily machined and fabricated, making it versatile for various aerospace and engineering applications.

7075 Aerospace Aluminum Hex Bar

The hex bar, made from 7075 aluminum, has a hexagonal cross-section and is often used in applications that require a secure grip or specific design features, such as fasteners and fittings. The hex shape allows for easy handling and installation, making it a popular choice in aerospace and mechanical applications.

7075 aluminum is difficult to weld using traditional fusion techniques but is typically joined in aerospace applications through friction stir welding or riveting. Due to its high strength, it is easier to machine than to weld.

Applications of 7075 Aerospace Aluminum Bar Rod

7075 aluminum is widely used in aircraft structures such as wings, fuselage frames, and structural components that require a high strength-to-weight ratio.

  • 1. Wings: Since wings endure significant loads and need to minimize weight, the high strength and low weight of 7075 aluminum make it an ideal choice for wing frames and skins.
  • 2. Fuselage frames: The use of 7075 alloy in fuselage frames provides the necessary strength and stiffness to support the structural integrity of the entire aircraft.
  • 3. Landing gear: Landing gear structures need to withstand heavy impacts and loads, and the high strength characteristics of 7075 aluminum make it perform excellently in these applications.
  • 4. High-strength structural components: 7075 aluminum is also commonly used in other key aircraft parts, such as transmission systems and connectors, where the optimal balance between weight and strength is required.
