Anodizing is a controlled accelerated growth of natural oxide. It's done by submersing the part into an acid bath and running controlled current through the part. After the coating is grown, the coating can be dyed. Pictures are difficult to tell finishes in. The pic you show does not look like it is anodized. I'm not saying it is not but due to the coloring and shading I would not take it for anodized. It has more the look of copper coating that has been chemically treated or antiqued. Have you any knowledge of the production date of the part in the pic? Is this the part that you said would be susceptible to 550 to 650 degree heat? When you ask about non-standard finishes, do you refer to the finishes used or the appearances that are not normally seen?
