Anodising: Protection + Finishing
An anodised coating offers for your components surface protection, electrical insulation and decorative solutions. With a black anodised coating, additional improved heat radiation is achieved.

Aluminium surface finishing
Where the natural quality of the aluminium material is not sufficient, the aluminium surface is refined by an anodised layer. This layer can be up to 30µm thick. This surface treatment determines the final appearance of the product.
Applications for anodised aluminium are among others the electrical industry, the construction industry, the automotive industry and the food industry.
At Alutronic, anodic oxidation (anodising) is carried out using a direct current sulphuric acid process. In this process, the purity and condition of the aluminium is a decisive factor.
In the manufacturing process, electricity, H2O and H2SO4 transform the aluminium surface into aluminium oxide. This so-called anodised layer lies two parts in and one part on the workpiece.

Anodising & Advantages
Aluminium in its raw state reacts in the air and forms an uncontrollable, often unintended unsightly oxide layer due to the reaction with oxygen or weather-related influences. Anodising is a possibility for the controlled creation of a protective layer. In this process, the top layer of the part to be anodised is transformed and an oxide is formed. It protects your aluminium part from corrosion as long as there is no surface damage from scratches or similar on the surface.
What is anodising?
Anodising - also known as "anodising" or "anodising process" - is an electrochemical process. In the field of surface technology, the process is used to create a thick, protective and extremely hard layer over an aluminium workpiece in a controlled manner by means of anodic oxidation. In this process, the top layer of the workpiece is converted into an oxide or hydroxide. Depending on the desired application, it can reach a thickness of between 5 and 30 µm.

Manufactoring process
In the manufacturing process, electricity, H2O and H2SO4 transform the aluminium surface into aluminium oxide. This so-called anodised layer lies two parts in and one part on the workpiece.
Areas of application
Applications for anodised aluminium includeamong others the electrical industry, the construction industry, the automotive industry and the food industry. At Alutronic, anodic oxidation (anodising) is carried out using a direct current sulphuric acid process. In this process, the purity and quality of the aluminium is a decisive factor.
Anodised layer
This anodised layer is electrically non-conductive and has a high breakdown resistance. The workpiece is contacted in supports (frames) made of titanium or aluminium to ensure a safe current flow. The layers, which are colourless in themselves, can be coloured in different shades by incorporating colour pigments.
