Anodising - Type 2

How It Works

Anodising is an electrochemical process. Through the use of chemicals and electricity. This is accomplished by immersing the aluminum into an acid electrolyte bath and passing an electric current through the medium. The surface of the aluminium is converted to aluminium oxide and forms in a honey comb like effect as seen in the picture. 

This layer is used to increase the durability and corrosion resistance of the material, and allows numerous colouring and coating options.

​

Depending on the application, the layer can be coloured, left unsealed to accept dyes for printing, PTFE and lubricant impregnated, or post coated.

​

Aluminium selection, manufacturing techniques and process control all make an impact on the quality outcome. Please see manufacturing and considerations for further information.

​

Applications

Anodising is used in 30+ different industries from mobile phones and computers, to marine and architecture. The main reasons for anodising is for durability of the component, colour for aesthetics, and corrosion resistance. 

​

If it is made of aluminium, the uses are endless.

​

Some examples of these applications are:

General Engineering

Anodising for general manufacturing and engineering is used in a wide range of applications.

Components that require high wear resistance can be Type 3 hard anodised, coated with PTFE Teflon or post painted.

Architecture

Architecture uses anodising for colour and corrosion resistance. From external panels to internal brass looking parts. We can assist in meeting your requirements. 

Automotive and Motorsports

Anodising use for automotive and motorsports is as wide as the imagination. it is used from the elite V8 Supercars and race industry, to show cars and motocross. If it is made of aluminium, you can more then likely anodise it.

Cast is the only exception. Please see the cast page under FAQ for more details.

Marine and High Corrosion

Anodising for the marine industry is mainly based around corrosion resistance. A marine of high corrosion coating is thicker than the general coat to withstand a more extreme environment.

If your items are in an very high corrosion environment such as coal mining or the bottom of the ocean, you can also look into type 3 anodising for higher resistance depending on the application.
