6063 T5 Rectangular Aluminum Tube Anodized Hollow Profile for Machine Frames and Equipment Enclosures

This rectangular aluminum tube is extruded from 6063 alloy in the T5 temper, producing a hollow profile with straight sides and uniform wall thickness. It suits applications where a light, corrosion-resistant frame member is needed, and the rectangular section offers flat faces that are convenient for mounting panels, brackets and fittings. The finished tube holds its dimensions well and can be cut, drilled and tapped with standard shop tooling. The anodized finish is created by an electrolytic process that builds a thin oxide layer on the surface of the aluminum. This layer is part of the metal rather than a coating that can peel, and it gives the tube a clean, uniform appearance that resists fingerprints and ordinary handling marks. Anodizing is often chosen for visible frame parts and for enclosures where a consistent look across many lengths matters, and it offers some protection in indoor and sheltered outdoor use. Common uses include machine frames, equipment enclosures, work tables, guarding, display stands and structural trim. In these roles the profile is often joined with corner brackets, gussets or internal connectors, and the flat sides make it easy to attach side panels, doors and control plates. The hollow core keeps weight low while the rectangular shape delivers stiffness where a frame needs it. From a fabrication standpoint, 6063 is one of the more workable aluminum alloys. It machines cleanly, forms well in bending, and welds with common techniques, although the anodized layer should be removed locally before welding and the joint finished afterwards when a uniform appearance is needed. Cut ends can be deburred and either left bare or re-anodized. Wall thickness, outer dimensions, corner radius and length are the main variables to confirm before ordering. Because the tube is produced by extrusion, the die sets the exact cross-section; standard sections can be cut to length, while custom sections may require new tooling. Tolerances on dimensions and straightness should be agreed in advance so the parts fit without extra rework. For buyers, the practical points are the alloy and temper, the surface treatment, the cross-section drawing, the length and cut tolerance, and the packing method for transport. A clear drawing with dimensions and any critical tolerances helps avoid mismatches. This page describes the general characteristics of 6063 T5 rectangular anodized aluminum tube for machine frame and enclosure use. Exact dimensions, tolerances and finish requirements should be confirmed for each inquiry.
