I wouldn't use my Forrest blades either! HA! But since it is copper, a non-ferrous metal, and is thin, a carbide blade would have no trouble with it. The abrasive disc on the other hand, may be relatively thick, and produce more heat as well as a build up in the grit of the disc. Again, being thin, you probably don't have that much to worry about(I mean the metal, guy). HA!
