Anodising Pre-Treatment

Aluminium has long been a popular material due to its abundance as well as its ability to resist corrosion. For many manufacturers, using this metal for their products may not be enough. To further increase the visual appeal and durability of aluminium products, anodising, polishing and finishing may be applied.

For longer-lasting and more beautiful finishes, however, Badger Anodising Ltd. highly recommends our pre-treatment services before anodising aluminium. Aluminium surfaces can be improved and enhanced using our polishing techniques and the following pre-treatment services:

Etching

Etching produces a matt finish this will cover most extrusion lines, surface scratches and give an even coverage. If etching does not cover the extrusion lines, on your aluminium extrusions, we can also offer polishing which will blend in the surface prior to etching.

Semi-Bright

For those looking for a matt finish but with a little more style, we also offer semi-bright pre-treatments. This will also give an even coverage to aluminium, but with a brighter appearance when compared to just etching.

Chemical Brightening

Chemical brightening involves using a nitric acid-based chemical to produce a bright and decorative finish to colour work or silver, i.e. very good reflectivity for the lighting industry. This beautiful finish is preserved even better once the aluminium is anodised.

Please note, however, that not all aluminium alloys are ideally suited to chemical brightening. If you require any advice on this matter, please feel free to ring us and speak to one of our aluminium anodising experts.

Chromate Finishes

Chromate finishes provide good levels of corrosion resistance combined with low electrical resistance. This can be left just as a coating or as a base coat prior to paint or powder coating as chromate finishes provide excellent retention. This form of pre-treatment is commonly used for pre-treating aluminium used in the aircraft industry.

Trade names are:

  • Alocrom 1200 (yellow/straw colour)
  • Alocrom 1000 (clear finish)

All of our pre-treatment methods are meant to enhance the appearance and quality of aluminium. These treatments work best when use alongside our other metal finishing services.
