Product Overview
Tube en aluminium 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, bonne résistance à la corrosion, and superior machinability. Notre 6061 aluminum tubes are available as seamless tubes and extruded tubes, in T4, T5, T6 and T6511 tempers, produced per ASTM B210, ASTMB221, GB/T 4437, DANS 755 and JIS H4080 standards, with custom outer diameters, wall thicknesses, et longueurs.
