Why Use Color Anodizing?

Color Anodizing is a great way to add color to metal parts and products, such as the iPod Nano color cases. The color doesn’t scratch off! This is because the color is not just applied, the metal itself is dyed. The process is used most often with aluminum, but titanium, magnesium, zinc, and tantalum are also metals that tend to take color well due to their ability to react freely with oxygen. Aluminum and titanium are the most common choices because of their hardness and uses outside of anodizing. Anodizing has its own benefits, including mechanical properties like increased surface hardness, but the addition of color is primarily used for part differentiation/identification and cosmetic purposes such as brand recognition. Both of these roles are very important when it comes to manufacturing a high quality, marketable product.

So, why use this particular method to add color to metal products? For one, it is the most effective. Again, the type of metal does matter when it comes to the addition of color. Along with the metal, the particular anodizing method and how long the metal is anodized are important to how well the color will take, but for the most part when the dyes are added directly to the metal, the color will affix in the same way that it does when applied to textiles. This is because the anodizing process opens the pores of the metal surface allowing the dye to adhere, where as if color id added before anodizing takes place, the dye will simply run off the surface as the pres will be too small. Again, depending on the specific method and metal type, there are many considerations for color, including multi-color options. This would be ideal for logos and graphics on products such as control panels, cover places and face plates.

Another reason to color metals during the anodizing process is because it is better for the environment than other dying methods. Pollution from dyes can have serious repercussions, and researchers in the U.S. and China are currently looking into solutions and preventative measure to limit such pollutants and their negative effects on the environment. However, the color anodizing dyeing process is known to create less pollution and also produces a lot less left over materials than other dyeing methods, so it can be seen as a step in the right direction when it comes to protecting our ground water, and thus agriculture, as well as the planet as a whole.

So, whether your company is interested in dyeing metal parts for identification purposes or for brand recognition, or just cosmetic appeal in general, look into the world of color anodizing today and discover all of the benefits you can expect when the color anodizing process is used. Remember, the advantages extend beyond the quality and striking appearance of your product as the process is more responsible in terms of pollution prevention and sustainability.
