Anodized 6063 Aluminum Square Tube Milled And Threaded For Furniture

What This Anodized 6063 Aluminum Square Tube Is

This anodized 6063 aluminum square tube is an extruded aluminium profile with a square section, supplied in custom sizes and finished with an anodized surface. Alloy 6063 is a common extrusion alloy chosen for its smooth surface and good formability, which makes it well suited to visible tube that has to be cut, drilled, milled and threaded before assembly. The anodized surface builds an oxide layer on the aluminium, giving a uniform colour and a harder, more durable skin than bare extruded metal.

The tube is offered with milling and threading deep processing, so it can be delivered as a partly finished component with machined ends, slots or threads instead of a plain cut length. For furniture production this removes a machining step from the customer line and helps keep the fit between tube and fitting consistent.

Where It Is Used

• Furniture frames, legs and supports
• Shelving, display and shop fitting structures
• Handrails, trim and architectural tube work
• General square tube frames that need a clean anodized finish

How to Choose the Tube

Confirm the section size and the wall thickness from the load and the span, since a square section gains stiffness quickly as its side and wall increase. Set the length and the cutting tolerance next, and decide whether the tube is delivered as a plain length or as a machined part with milled slots or tapped ends.

Choose the alloy and temper with the process in mind: 6063 is well suited to extrusion, bending and clean anodizing, while a harder temper gives more strength but less freedom in forming. Decide the anodized colour and finish, and confirm whether the surface must match parts already in production.

What to Confirm Before Ordering

Before ordering, confirm the outside dimensions, the wall thickness, the corner radius, the length and the cutting tolerance. Confirm the alloy and temper, and state which machining operations are required, including milling, drilling, tapping or threading, together with the position and size of each feature.

Confirm the anodizing colour and the required surface quality, and whether the finish must match an existing sample. Finally, confirm the order in which the tube is machined and anodized, because machining after anodizing exposes bare metal and machining before anodizing keeps the whole surface protected.
