Remember, you can't beat the look of anodised aluminium. If you are not sure if anodising is what you need, why not ask us to do a FREE sample piece for you, we are more than happy to work with you to ensure you get the results you want.

 

Benefits of Anodising

 

There are several benefits to getting you products anodised;

 

  • Anodising is corrosion resistant - The Aluminium Oxide coating is very resistant to chemical attack, and is only really affected by strong acids or alkalis
  • Anodising is wear & scratch resistant - The anodised layer is much harder than the Aluminium substrate underneath.  Aluminium oxide is in itself a very hard substance, it measures 9 on the Moh scale of hardness (diamond is 10 on Moh scale).  Aluminium Oxide is used as an abrasive product in sand papers due to it's hardness.
  • Anodising won't peel or flake - The anodised layer is a part of the Aluminium and itself, not a separate layer like powder coating
  • Anodising is easy to clean - All it takes is soap and water, but avoid extreme abrasives
  • Finger prints don't show - Now there is a bonus
  • Old anodised coatings are easily redone - It is easy to strip of the old anodising, clean the product and re-anodise.  This is frequently done if the product is showing signs of wear or if you just want to change the colour
  • Choice of colour & finish - Gloss or matt and a huge range of colours (except 'white'), see our services page for the full range of colours

While anodizing offers many benefits, there are some things to be aware of with regard to the final finish;


  • Colour matching can be problematic - There are many variables in the anodising process that will impact on the final colour, and so while every effort will be made to match the colour in each anodising run and between different runs an exact match cannot be guaranteed
  • Colour choices for external use are a little more limited - UV stability becomes an important feature in choosing the dye when working with external anodised applications.  Please let us know what your requirements are, as not all dyes are suitable for external use
  • Anodising wont hide existing visible marks - Any marks such as die lines, machining marks or marks from handling i.e. scratches, dents, etc, will show through in the final anodised finish.  The finished look of the anodising is highly dependent on the surface finish before anodising.

 

 

 

How to get the best out of your Anodising and other tips


Here are some general pointers to take into account when getting anodising done:

  • Anodising does not hide marks present on the surface of the Aluminium before anodising e.g. scratches, clamp mark , die lines etc.........  These marks must be removed before anodising.  In some instances chemical etching can be used to reduce the impact of these marks but you will end up with a matt finish.
  • When sending your job away to be anodised, make sure the parts are packaged in a way that they cant be easily damaged or marked.  We have had instances where brand new parts have been sent to us with all the parts able to rub together in the packaging.  Needless to say there a cost involved in getting the parts ready to anodise.
  • If the parts need to be welded, do this before the product is anodised.  The anodised coating has very high resistance, effectively stopping welding and the anodizing needs to be removed before welding can take place.  (To remove the anodized layer for welding either use mechanical means or apply caustic based chemical e.g. oven cleaner - please take all safety precautions)
  • If welding , then use 5356 welding rod for the best looking results.  TIG welding is generally considered to be more suitable for aluminium to be anodised than MIG.  MIG welding generally results in very high localised heat around the weld that cools very quick after welding.  The result of this very quick cooling are structural changes to the Aluminium around the weld that wont anodise properly and wont take dye - No good for that decorative look.  This problem can be reduced or eliminated by preheating the aluminium around the area to be welded and works by slowing the rate of cooling after welding is completed.  As TIG welding typically requires pre-heating, problems with anodising are less common.
  • If you have a product that needs to be formed or shaped in any way, then this needs to be done BEFORE anodising.  While the anodised coating is very hard and resistant to wear, it does not like excessive tension.  Should an anodised layer be bent past a critical point the anodising will get fracture marks.  These fractures can become openings to corrosion.
  • If you have a colour sample available, please send this either with the job or email a photo.  This will help us to get the colour you are after.

(Please note, that while every effort will be made to match the colour this cannot be guaranteed as there are many variables that impact on the final colour)

(Please note that 'white' is not available as a colour, this is due to the fact that the particles that make up white dye are too big to fit into the pores generated by anodising.)

  • When packaging avoid putting any tape directly on the Aluminium, as it is difficult to clean off and is not removed by the anodising process.
  • Remember that anodising is only suitable for Aluminium and its alloys, this is because anodizing is an oxidation process.  Iron products such as steel would just turn to rust if they were to be anodised.
  • If the product has any non-aluminium metal attached, this either needs to be removed prior to sending the product or let the anodiser know so they can mask it before anodising.
  • Avoid leaving finger print marks on un-coated Aluminium products as these can become imprinted on the surface of the metal.  In some cases these marks will show through in the final product.
