Product Overview
アルミチューブ 6061 is a precipitation-hardened aluminum-magnesium-silicon (Al-Mg-Si) alloy tube, one of the most versatile and widely used aluminum alloys for structural applications. It combines medium-to-high strength, excellent weldability, 良好な耐食性, and superior machinability. Our 6061 aluminum tubes are available as seamless tubes and extruded tubes, in T4, T5, T6 and T6511 tempers, produced per ASTM B210, ASTM B221, ギガバイト/トン 4437, で 755 and JIS H4080 standards, with custom outer diameters, wall thicknesses, and lengths.
