aluminum anodizing

Aluminum anodizing is basically an electrolytic passivation process used to increase the thickness of the natural oxide layer on metal surfaces, which increase the corrosion resistance on the material. The anodic film that is formed around the metal, thou more brittle, is much stronger and adherent than most types of paint, it is also less likely to crack, but more susceptible to crack from thermal stress.

Some aluminum foundries offer aluminum finishing services, on which they include aluminum anodizing, this might be a huge advantage for your time requirements, be sure to check your requirements and your aluminum casting provider services.
