This 4.25" diameter aluminum round bar is made from 7075 alloy with a T651 temper and cold finish, offering high strength with an ultimate tensile strength of 80 ksi and good machinability rated at 70. It provides excellent fatigue resistance and strength slightly superior to steel while maintaining aluminum's light weight.

Yes, custom cut lengths are available from the warehouse. The bar can be ordered in lengths ranging from 12 inches up to 144 inches, with multiple length options in stock and ready to ship.

Yes, this aluminum round bar complies with RoHS and REACH standards and comes with a Material Test Report (MTR) available to verify its quality and compliance.

This high-strength aluminum alloy bar is ideal for aerospace, high-end automotive, and defense applications due to its excellent strength-to-weight ratio, fatigue resistance, and average corrosion resistance.

The 12-inch length bar weighs approximately 17.19 pounds and shipping weights scale proportionally with length. The product is stocked and shipped from a domestic warehouse.
