Anodising is the name for the treatment of aluminium to produce a natural oxide coating for protection, wear resistance and decoration.

Aluminium components are anodised by placing them in a solution; a voltage is applied causing an oxide film to be produced at a controlled rate to a desired thickness. This anodic film is not a surface coating, but is part of the material.

Standard Sulphuric Anodising provides a silver coloured finish showing the natural colour of the metal but components can also be dyed in a range of colours to provide eye-catching effects. Our own standard colors are Red, Blue, Black, Silver and Gold as standard. MAny more colours are available upon request

Sulphuric Acid Anodising

The most common form of anodising is sulphuric acid anodising.

An anodic film thickness of up to 30microns can be produced, depending on the grade of alloy and end use of the components. The lower range of thickness is ideal for decorative finishes, and the medium range is ideal for dyeing.

Etching, polishing, and Rumbling prior to anodising may be carried out to enhance the component's appearance.The oxide film produced provides the surface of the aluminium with an extremely hard, durable, and long lasting finish.

Sulphuric Acid Anodising provides a cost-effective way to enhance the performance and appearance of Aluminium.
