OABIC, OIA, and BRUT finishes in anodizing

March 30, 2009

Hi,
Thanks in advance for your time.
I would like to know what is OABIC, OAI, BRUT finishes in aluminum anodizing? How they are different from Type 1,2 & 3 of Aerospace specifications?

Do they imply any specific process or just color codes?
