Sulphuric Acid Anodising


Sulphuric acid anodising (also known as Architectural anodising) was developed in the 1930’s for military and architectural applications. Using a dilute Sulphuric acid solution and operating at room temperature (~18°C), this process is widely accepted as the best choice for decorative applications. The oxide layer produced is usually clear, allowing the silver colour of the Aluminium to shine through, and is particularly good for subsequent dyeing to produce a range of attractive metallic colours. Film thicknesses vary greatly depending on the application. Thinner films (3 to 10 microns) offer low levels of protection but are economic and easy to apply, thicker films (15 to 25 microns) absorb dye well and offer better corrosion resistance and mechanical performance characteristics, making them a prime choice for architectural applications.

Applications include: 


  • Architectural components – e.g. windows, doors, handles, hinges etc
  • Cookware / bakeware.
  • Decorative components (e.g. lighting, bicycle components, mountain climbing / hiking gear, tennis rackets etc.)

In fact any item which requires good corrosion protection and electrical insulation without loss of fatigue strength.
