All I know about anodizing is that it is often done to provide a protective coat to aluminum. While aluminum doesn’t rust, it does form a crusty surface under some conditions (aluminum oxide?). I don’t know if anodization can be made in any color, but it is done in lots of colors. Aluminum pistol frames are often anodized black, for example.
All that said, and you guys know I am a moron when it comes to this sort of scientific stuff, I can’t honest say that the WCC .45 cases are really anodized. I simply don’t know what process is used to form a protective, colored coating on them. I am afraid that if aluminum is any color other than silver/gray, I refer to it as “anodized,” although I know there are other aluminum finishes and sometimes they are just a protective coat, and don’t really “color” the casing, as in most CCI aluminum-cased ammo.
I should have qualified my remark about “anodized” in my original answer, or used more general terms. Sorry about that. To paraphrase “Dirty Harry,” I do know my limitations, and they are many!
Thanks for the explanation. It was fairly clear even to me, and interesting. I am not sure that even the huge amount of expertise and talent that exists on this Forum can help a dolt like me, but I enjoy the answers regardless.
Schneider - thanks for the information on the use of silver. I know that silver especially, and sometimes gold, have industrial uses beyond its use in jewelry.
