Colour-anodised aluminium components are used wherever a certain degree of corrosion and wear protection is required in combination with a decorative colour. This can be in the field of architecture as well as in electrical engineering, photo and video technology, in household appliances, hunting weapons, sporting goods or in the motorcycle industry. Of course, there are also applications in the automotive or mechanical engineering.
Applications for colour anodisation of titanium materials can be found, amongst others, in medical technology: Implants made from a titanium material, which temporarily remain in the human body to heal fractures, are colour anodised. This helps the surgeon to quickly identify the components. The coated implants are neutral in the body. They do not grow together with bone and tissue and can be easily removed after healing.
Because of their biocompatibility and their decorative appearance, the application of coloured titanium oxide coatings is also useful in the optical and jewellery industries, e.g. for watches or costume jewellery. In the motorcycle industry, titanium materials meet the demand for maximum strength and low weight. The colour anodised surface, for example of wheel nuts, meets the design requirements of the customers. In addition to the colour, the oxide layer serves as a diffusion barrier to the titanium material. Since the coating insulates very well electrically, it can also be used in electrical engineering.
