We can find a variety of products in aluminum material with different beautiful colors in our daily lives, but how to color aluminums?
The anodizing process is a reputable method, it forms a layer of oxide on the metal surface, which helps to resist corrosion, scratches, and fading. It is also used to add a color to aluminum.
After anodizing, aluminium is still 100% pure and recyclable.
Anodized aluminum is a popular choice for product developers due to its attractive appearance and durable finish.
Adding color to aluminum during anodizing can be done in two ways.
One is electrolytic coloring. The component is immersed in the third tank of the solution, which also contains metallic salts.
Dip dyeing, or just dipping the item in a dye tank, is the second method.
After the dye has been absorbed into the pores, the surface is boiled in deionized water to stop any further reactions.
However anodizing colors are different from powder coating or painting. In terms of achieving color consistency, there are difficulties due to the many variables involved in anodization.
Getting a match of the right colors can be difficult, especially when they are of different batches.
It is important to understand the idea of color matching and essential factors that affects the anodizing.
