Sulphuric Anodising
An electrolytic treatment for aluminium that produces a coating of aluminium oxide. We offer clear anodise as well as a variety of colours: black, gun metal grey, red, orange, yellow, green, blue, purple, pink and gold.
​
By altering the dyeing process, we are able to achieve a range of shades. We are happy to provide colour samples.
​
The standard micron thickness range for this finish is 5 to 25 microns.
Beyond this range hard anodising is required.
​
Nickel acetate seal, demineralised hot water seal and PTFE seal (providing the lowest coefficient of friction of any solid) are also available.
​
We are able to anodise to the dimensions of: 2.4m x 0.8m x 0.9m.
Profile
Sulphuric acid anodising occurs as a result of electrolysis. Using electricity and a sulphuric acid electrolytic solution, oxidation of the aluminium surface occurs to form a thin, hard film of aluminium oxide. This surface treatment provides excellent corrosion resistance and can be dyed in a range of colours. The sulphuric acid anodising process, including passivation, is entirely chromium VI free and so meets the requirements of the latest legislation.
