Anodising:
(Sulphuric)
​
For aluminium protection and optional colouring.
Anodising is an electro chemical process, which physically alters the surface of the alloy to create a hardened, protective outer layer of aluminium oxide.The oxide layer is initially porous allowing the introduction of a coloured dye. Alternatively the dye can be omitted for a natural finish (clear anodising). Heating in water then seals the porous layer. This crystallises the oxide layer permanently trapping the dye beneath the surface for an attractive coloured finish which lasts.
​
Anodising increases resistance to corrosion, abrasion and wear.
The anodic film produced provides aluminium with an excellent tough protection outer layer with optional colouring.
​
The finished oxide surface also provides far greater resistance to heat and electrical insulation. Our wide range of colours include: Blue, Gold, Green, Orange, Red, Violet, Satin or Natural. The process is unsuitable for riveted items, sealed joints, sealed tubes, or other items where there is a risk of electrolyte becoming trapped in blind holes.
