Like steel, Aluminum also corrodes but it is not visible as the corrosion byproduct also has the same colour as that of Aluminum. Chromating is a conversion coating which passivates the Aluminum surface when dipped in the solution. On chromating, the surface turns pale green in colour and high silicone content aluminum alloy turns grey in colour.

- Operates in ambient temperature
- Provides uniform finish
- Aluminum components and sheets prior to painting or assembly
