Anodizing is a type of surface treatment that can be done to certain metals like aluminum and titanium. Using an electrical source and a sulfuric acid bath, a microscopic layer of oxide is 'grown' on the surface of the metal.
With aluminum, this oxide layer not only provides abrasion resistance, but the layer can be colored with a vast array of dyes and masking techniques.
Once the dye is sealed into the oxide layer, the coloration becomes highly resistant to solvents and harsh environments, making this a very durable way to finish aluminum.
Using surface treatments like polishing, hammering, mill rolling, sandblasting, and etching in conjunction with anodizing provides an almost endless array of potential effects.
