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.
