Product Overview
Aluminum Round Bar 6061 is a precipitation-hardened aluminum-magnesium-silicon (Al-Mg-Si) alloy rod, one of the most versatile and widely machined aluminum products in the industry. It combines medium-to-high strength, excellent machinability, good weldability, and superior corrosion resistance. Наш 6061 aluminum round bars are available in T4, T6, T651 and T6511 tempers, produced per ASTM B211, ГБ/Т 3191, В 755 and JIS H4040 standards, with diameters from 3 mm to 500 mm and custom lengths.
