Aluminum AlloyBar/Rod
Description (English)
7075-T6 Aluminum Round Bar is a high-strength aluminum alloy with zinc, magnesium, and copper as its principal alloying elements. It provides excellent tensile strength, high stress resistance, good machinability, and a favorable strength-to-weight ratio. It is widely used for aerospace components, aircraft structures, defense equipment, automotive parts, shafts, gears, fittings, and precision-machined components. Customized diameters, lengths, cutting, machining, surface treatment, inspection, and Mill Test Certificates are available according to customer requirements.
