Capral Anodising Hero.jpg Anodising process
Aluminium anodising is an electrochemical process creating a chemically coated anodic layer on the surface of the aluminium. This anodic layer is an insulator and can be coloured electrically in a wide variety of colours. The anodic layer provides superior surface corrosion protection as well as hardness. The hardness of
anodised aluminium is the second hardest substance after diamonds.

Service offer
Capral’s superior service offer, combined with short lead times and excellent quality are a proposition that is hard to match in today’s market. Capral can offer anodising from its own extrusion presses as well as sheet anodising and customer own extrusions (on application) in film thicknesses ranging from 10 micron to 25 micron. 10 – 15μm is recommended for interior use and 20 – 25μm for external use. Capral strongly recommends the use of 25μm for coastal areas and equivalently harsh environments.

Australian Standards
Capral Anodising meets all the required standards and accreditation's including, AS1231; ISO 9001, ISO 14001 and AS 4801. The Bremer Park facility has its own laboratory to ensure superior process and total quality control.
Capral offers warranties ranging from 10 through to 20 years to meet even the most discerning customer’s requirements.

Capral’s anodising line produces a wide range of anodised colours: Conventional Matt Clear Anodising; Electro coloured Bronzes and Black, as well as Capral’s new range of ‘Interference’ colours. Colour matching or custom colours to meet specific architectural requests can also be accommodated.

Capral Anodising Samples.jpg Definitions
Conventional Matt: 

Prior to the anodising process, a caustic chemical pre-treatment process is used to produce a matt finish. This process aids in the reduced visibility of extrusion defects and eliminating mild scratches from the material’s surface.

Electro-Colouring: 

After etching and creating the anodic layer, colour can be added to the layer by electrically depositing metal substances. The substance in the anodic layer reflects the ambient light and produces Capral’s range of colours. Slight colour variations between different alloys and production batches are to be expected. Capral’s use of a Spectrophotometer ensures that colour variations are reduced to a minimum.
