Aluminum electro coloring Transformer is used to color anodized aluminum through electrolytic means. This method is widely used in various industries, including architecture and electronics, due to its durability and aesthetic appeal. Here are some key points about the process:

1. Process: The anodized aluminum is immersed in a solution containing metallic salts, and an AC or DC voltage is applied. This causes metallic deposits to form at the bottom of the pores in the anodized layer, resulting in different colors depending on the metal used.
2. Metals Used: Common metals used in this process include tin, nickel, and cobalt, which can produce colors ranging from bronze to black. Copper can also be used to achieve red hues.
