Product Overview
Tubo de aluminio 6063 is an aluminum-magnesium-silicon (Al-Mg-Si) alloy tube renowned for its excellent extrudability, outstanding surface finish quality, and superior anodizing response. It is the first choice for architectural, decorativo, and consumer applications where appearance and formability matter most. Nuestro 6063 aluminum tubes are available in T4, T5 and T6 tempers, produced per ASTM B221, EN 755, GB/T 5237 and JIS H4100 standards, with custom outer diameters, wall thicknesses, lengths, and anodized or powder-coated finishes.
