Aluminium has its own built in anti-corrosion system, as when the metal is exposed to the air, a layer of oxide is created, which stops corrosion. By anodising the aluminium, an even coat is grown into the surface, and with the use of dyes, any colour can be achieved. The clean look of anodised aluminium, combined with the low maintenance, makes it easy to understand why anodised aluminium is so popular.
Starting a business involves a certain level of investment, and one wants that investment to be a lasting solution, so corrosion solutions are paramount in all planning. Shops, restaurants, and other public venues, enjoy the benefits of anodised aluminium, with years of untroubled activity, and no maintenance, apart from a regular clean. If a person is looking for quality natural anodised aluminium with Anodisers in WA, there are online companies that produce and supply all types of anodised aluminium. Untreated aluminium loses its shine after a while, and is not pleasing to the eye, whereas anodising gives a hard, even finish, and with a range of thicknesses and colours, is the perfect material for many uses.
Not a surface application
The big difference between paint and natural anodised aluminium is that the finish is set into the aluminium surface, rather than applied on top, which means the surface is protected throughout, whatever the conditions. The chemical process which causes the oxidisation ensures that the finish is durable and long-lasting, and with fine control over all the elements of the anodisation process, the thickness of the coating can be accurately defined. Paint tends to peel and crack with age, whereas anodised aluminium will remain in pristine condition, and only needs a clean now and then.
Low thermal conductivity
Anodised coatings have a lower thermal conductivity that regular aluminium, which means the coating might crack at temperatures in excess of 80 degrees C. Aluminium anodising is usually carried out with an acid solution, and this slowly dissolves the aluminium oxide. The oxidation rate is balanced with the acid action to form a layer over the aluminium surface, which is finely measured to meet the customer’s specifications.
A controlled environment
The concentration of electrolyte, the acidity, the amount of current used, and the temperature of the solution, must all be controlled if the coating is to be perfect. Harder, thicker coatings require a more diluted solution at lower temperatures, with higher voltages and currents used. Film thicknesses range from 0.5 micrometers for decorative use, to 150 micrometers for architectural support.
Fix and forget
Aluminium that has been anodised is basically maintenance free, and therefore popular with all applications, whether at home, or at the place of business, allowing for the aesthetic appeal, without the constant need for cleaning. The fresh look of natural anodised aluminium is another benefit, and with a range of innovative finishes, there will be something to suit every setting.
Anodising protects aluminium, and allows a range of colours and finishes to be applied, which provides many businesses with the ideal material for their products.
