On carbon steel anodising is of no use because rust puffs up and flakes off, constantly exposing new metal to corrosion. With aluminium however, anodising will increase its corrosion resistance.
Anodising is also used for a number of cosmetic effects, either with thick porous coatings that can absorb dyes or with thin transparent coatings that add interference effects to reflected light. Anodising changes the microscopic texture of the surface and can change the crystal structure of the metal near the surface. Coatings are often porous and thick, so a sealing process is most often used to improve corrosion resistance.
What is Alumium Anodising?
What we Do
Anodising is an electro-chemical process used to increase the thickness and density of the surface of metal parts.
The process derives its name from the fact that the part to be treated forms the anode portion of an electrical circuit in this electrolytic process. Anodising is generally much stronger and more adherent than most paints and plating, making the aluminium less likely to crack and peel.
Astro Anodising is the division in the Group offering superior anodising services to manufacturers using aluminium in the production of their end products. These customers are spread over scores of different industries including those in the automotive and architectural sectors. With our large selection of colours and finishes and our capability to anodise work in sizes ranging from small cast or machined components right up to lengths of 7.5m we are truly your "one stop shop".
