Aluminum round bar 7075 is a high-strength, heat-treatable aluminum alloy that is commonly used in aerospace, automotive, and other high-performance applications. It is known for its excellent strength-to-weight ratio, superior mechanical properties, and good corrosion resistance.

Here are some key features and benefits of aluminum round bar 7075:

1. High strength: Aluminum round bar 7075 is one of the strongest aluminum alloys, with a tensile strength of around 83,000 psi (570 MPa) in the annealed condition, and even higher when heat-treated. It has excellent fatigue strength, making it suitable for applications that require high-strength and durability.
2. Lightweight: Despite its high strength, aluminum round bar 7075 is relatively lightweight compared to many other materials, making it ideal for weight-sensitive applications where reducing weight is important, such as aerospace and automotive components.
3. Heat-treatable: Aluminum round bar 7075 can be heat-treated to further enhance its mechanical properties, including strength, hardness, and toughness. This allows for customizing the material’s properties to suit specific application requirements.
4. Corrosion resistance: Aluminum round bar 7075 has good corrosion resistance, particularly in atmospheric environments. It forms a protective oxide layer on the surface that helps to resist corrosion and improves its durability.
5. Machinability: Although aluminum round bar 7075 is considered to have fair to poor machinability, it can be machined with proper techniques and tooling. It is recommended to use carbide tooling and cutting fluids to achieve the best results.
6. Wide range of applications: Aluminum round bar 7075 is commonly used in aerospace, automotive, military, and other high-performance applications where strength, durability, and lightweight properties are required. It is used for components such as aircraft fittings, structural parts, landing gear, missile parts, and high-stress automotive parts.
7. Excellent anodizing response: Aluminum round bar 7075 has an excellent anodizing response, which makes it suitable for applications that require decorative or protective surface finishes.
8. Recyclable: Like other aluminum alloys, aluminum round bar 7075 is recyclable, making it a sustainable and environmentally friendly choice.

It’s important to work with a reputable supplier and follow proper handling, machining, and heat-treatment procedures when working with aluminum round bar 7075 to ensure its optimum performance and to meet specific application requirements.
