Learn more about casting anodization

Casting anodization is an anodizing process that is particularly suitable for cast aluminum blanks. Casting anodization is used, among other things, to create results such as increased corrosion resistance, a dirt-repellent surface, a decorative surface or a surface with an electrically insulating coating.

Anodizing in castings will, in contrast to normal anodizing, add a rougher surface and at the same time require a different pre-treatment before starting the anodizing process.

Cast aluminum is a popular and versatile material in many industrial applications due to its strength, durability and lightness. One of the most common surface treatments for cast aluminum is anodizing, which can give the material a protective and decorative layer.

Anodizing is an electrochemical process where the aluminum surface is exposed to an acid that creates an oxide film on the surface of the material. This oxide film acts as a protective layer against corrosion and wear, while it can be colored to give a decorative effect. In the case of cast aluminium, however, a pure alloy is required.

Anodizing cast aluminum has several advantages. First of all, it protects the material against corrosion and scratches, which increases the life and durability of the product. It also makes the material more resistant to chemical and thermal influences. Anodizing can also increase the electrical insulation of the surface and improve its resistance to electrical charging and electrolysis.

When anodizing cast aluminium, it is important to take into account the material's composition and surface properties. Different casting alloys require different anodizing processes, and the surface of cast aluminum can be uneven and have porous areas that can affect the anodizing process.

Therefore, it is a good idea to work with a professional anodizing company that has experience with cast aluminum and can adapt the anodizing process to the material's specifications. An experienced anodizing company can also advise on the best type of anodizing for your product and help achieve the desired result.

Anodizing cast aluminum is an effective and popular surface treatment that can improve the material's durability, resistance and decorative appearance. By working with a professional anodizing company, you can achieve the best results and protect your product from corrosion and wear.
