Al7075 T6 ASME SB 211 AA7075-T651 Aluminum Round Bar Manufacturer and Aluminium Flat bar supplier RAYIWELL MFG is a professional factory of feuille d'aluminium, barre en aluminium, ou plaque d'aluminium en Chine.
7075 (UNS A97075) is an aerospace aluminum round bar with cold finished or extruded aluminum wrought alloy with high strength, adequate machinability and improved stress corrosion control. Fine grain control results in good tool wear
7075 is one of the highest strength aluminum alloys. It has good fatigue strength and average machinability. Often used where parts are highly stressed. It is not weld able and has less corrosion resistance than other aluminum alloys. The mechanical properties depend on the temper of the material. Commonly used in the bicycle industry, aircraft structures, and in rifles for the American military. We stock 7075-T651, 7075-T6511, 7075-T7351, 7075-T3511 and 7075-T76511.

What Are the Key Properties of 7075 Aluminum Round Bars that Make Them Ideal for Aerospace Applications?
The key properties of 7075 round bars that make them ideal for aerospace applications are:
1. Haute résistance: 7075 round bars have a high tensile strength, which makes them suitable for withstanding high stress and pressure in aerospace applications. They have a yield strength of 73,000 psi and a tensile strength of 83,000 psi.
2. Poids léger: Despite their high strength, 7075 round bars are relatively lightweight compared to other metals. This is crucial in aerospace applications where weight reduction is essential to enhance fuel efficiency and overall performance.
3. Résistance à la corrosion: 7075 round bars have excellent corrosion resistance, particularly against atmospheric conditions and seawater. This property is vital in aerospace applications where the material may be exposed to harsh environments.
4. Heat treatability: 7075 round bars can be easily heat treated to enhance their mechanical properties, such as strength and hardness. This flexibility allows manufacturers to optimize the material’s performance to meet specific aerospace requirements.
5. Usinabilité: Although 7075 round bars are known for their high strength, they still possess good machinability. This makes them easier to shape, cut, and drill, enabling efficient manufacturing processes in aerospace applications.
6. Fatigue resistance: 7075 round bars exhibit excellent fatigue resistance, allowing them to withstand repeated loading and cyclic stresses without failure. This property is crucial in aerospace applications where components must endure constant stress and vibrations.
7. Weldability: 7075 round bars have good weldability, which enables them to be joined with other materials or components in aerospace manufacturing processes. This property facilitates the construction of complex structures and assemblies.
Dans l'ensemble, the combination of high strength, lightweight, résistance à la corrosion, heat treatability, usinabilité, Resistance à la fatigue, and weldability makes 7075 aluminum round bars an ideal choice for aerospace applications.
