Anodised Aluminium Tube - 6063 and 7075 Alloy Piping for Fabricated Frames
Anodised Aluminium Tube in 6063 and 7075 Alloys
This tube is supplied as anodised aluminium piping in two alloy options, 6063 and 7075. Both grades are aluminium alloys that take an anodic finish well, and both are supplied in the same round tube form, so a buyer can choose the grade that fits the job without changing the way the part is cut, bent or joined. The tube is used as piping for frames, rails and other fabricated tubular work where an even, protected surface is wanted.
The 6063 grade is the general purpose extrusion alloy, chosen when the part needs a clean surface and easy forming. The 7075 grade belongs to the 7000 series and is picked when more strength is needed in the same tube section. Offering both lets the same drawing be built in a lighter duty or a higher strength version without reworking the design, and a single order can cover a frame that mixes lighter and heavier members.
Alloy Options
- 6063 aluminium alloy for general frame and piping work.
- 7075 aluminium alloy for higher strength tubular parts.
- Round tube section suited to cutting, bending and joining.
- Anodised surface on both grades.
- Two grades available in the same tube form.
The Anodised Surface
Anodising is an electrochemical treatment that builds an oxide layer from the aluminium itself. Because the layer is formed from the metal, it does not chip off at edges or bend points in the way a thin paint film can, and it leaves the tube looking uniform along its length. On a working pipe the finish limits the scuffing caused by handling and stacking, and it slows the surface corrosion that starts when bare aluminium meets moisture.
Working the Tube
The tube can be cut to length, bent into curved runs and joined by welding or mechanical fittings. Because both alloys are supplied in a consistent round section, the same tooling and the same bend angles can be used whichever grade is chosen, which keeps changeovers simple when a frame is built in more than one strength level.
Typical Uses
- Frames and rails built from anodised aluminium piping.
- Tubular parts that need a protected, even surface.
- Light structures in 6063 where easy forming matters.
- Higher strength tubular parts in 7075.
Ordering
Tube lengths and the alloy grade can be chosen to suit the part being built. Buyers who need the tube in a formed shape can supply a drawing or sample, while those who only need the straight pipe can order it on its own.
