7075 Aluminum Round Bar （7075 Aluminum Rod）

Certainly, the 7075 alloy is perfect for such applications. It is extremely strong with a 572 MPa tensile strength, meaning that it can resist a lot of forces. That’s why it performs excellently in high-stress environments such as in racing cars and aircraft.

The 7075 aluminum round bars may be corrosion-resistant, but it is still advisable to be wary of the environment. Even if not immediately, the material gets affected by exposure to alkaline and acidic elements. If you think the rods will be exposed to such environments for a long time, consider applying a protective layer and performing regular maintenance.

Yes, you can, but with extra care. The 7075 aluminum alloy may have good corrosion resistance, but there are limits as to the duration of exposure. We wouldn’t advise you to use the rods where they will be constantly exposed to a corrosive environment. But if you need to apply the strength factor in the project, then you must counter the corrosion challenge. A quality protective coating may work in your favor. It can safeguard the alloy against the corrosion effects of saltwater. That way, you can enjoy the superior performance of 7075 aluminum round bars in high-stress applications.

If you can accept the strength property of 5083 alloy, the 5083 aluminum rods will be more suitable to use in a marine project.

The 7075 aluminum round bars are suitable for anodizing. Anodizing is a beneficial process that can add aesthetic appeal and durability to the alloy.  When you anodize the round bars, you are enhancing the oxide layer, which is natural to the alloy. Apart from decorating the surface, the process makes the surface harder, enhancing wear resistance.

Most customers have the same question. We always reiterate that the relatively high cost of the alloy is justifiable. This is a premium material that offers better properties than the regular aluminum alloys. Applications that need superior performance and strength may not find a replacement for this alloy. It is a cost-effective answer to the need for reliability and durability in critical applications.

Yes, there are particular precautions needed when machining this 7075 alloy. Remember you are dealing with a significantly strong material, and in most cases, only carbide tools will do the job cleanly. Lubrication is also necessary for the same reason. Due to the potential heat generation during the machining process, you want to use a coolant for heat dissipation. This will also help keep the tool in good shape for longer. With these precautions, you should machine the 7075 round bars flawlessly.

We have custom lengths of the 7075 aluminum rod based on the requests from our customers. It all depends on the specifics of your project requirements. With this flexibility in length, we can minimize challenges where the customer has to do a lot of machining. Any subsequent processing steps are also minimized. Based on the length requirement, no project is too large- or small-scale for us. Whatever your project specifications are, we have a 7075 aluminum round bar that is long enough.

The temper T73 after solution treatment reduces the material strength by 1 0 %-15 % , and the corrosion resistance is significantly improved . The 7075T73 aluminum round bars are mainly used for high-strength and corrosion-resistant rivet materials.

T73511 means solution treatment (quenching), stretching a certain amount to eliminate internal stress (1%~3% for extruded tubes, rods, profiles, 0.5%~3% for drawn pipes) and then over artificial aging until the material has the most excellent resistance to stress corrosion cracking. Straightening will be helpful to meet the standard dimensional deviation accuracy. Tensile Strength: >68 ksi , Yield Strength: >56ksi , Elongation: >10%.

The 7075T6 7075T651 7075T6511 aluminum round bars can be used if no precision requirement for dimensional stability and elastic allowance.
