6063 Aluminum Tube
The 6063 aluminum tube is a tubular material made from 6063 aluminum alloy. It belongs to the Al-Mg-Si series, a medium-strength, heat-treatable alloy known for its lightweight, corrosion resistance, and high workability.
6063 aluminum tube is a widely used extrusion product, known for its excellent corrosion resistance, formability, and aesthetic appearance, making it the preferred choice for architectural and structural applications.
The 6063 aluminum tube is made from 6000 series alloy 6063, a heat-treatable magnesium-silicon alloy highly praised for its outstanding extrudability, good mechanical strength, high corrosion resistance, and superior surface finish. Its balanced composition makes it easy to extrude into tubes and other constant cross-sectional shapes, and then age-treated to achieve tempers such as T5 or T6. 6063 aluminum tube offers high strength and is suitable for applications in architecture, structures, automotive, and general tubing.
