This aluminum round bar is made from 7075 alloy with a T651 temper and cold finish production method. It offers high strength (ultimate tensile strength of 80 ksi), good fatigue resistance, average machinability (70 rating), and weighs approximately 11.78 lb per 12-inch length. It also meets RoHS and REACH compliance standards.

Yes, custom cut lengths are available from the warehouse. Standard lengths range from 12 inches up to 144 inches, and you can select the desired cut length when ordering.

Absolutely. The 7075 alloy is one of the strongest aluminum alloys, designed specifically for aircraft frames and commonly used in aerospace, high-end automotive, and defense applications due to its strength slightly superior to steel while maintaining aluminum's lightweight.

The product is in stock with multiple length options available for immediate shipment. Shipping weights vary by length, for example, a 12-inch piece weighs about 11.78 lb, and longer lengths up to 144 inches are also available.
