not quite, some alloy is almost like chalk, some is more pure.
hence if you get a new volt shitty 21 inch chromed wheel and sand it back, the likelihood of being able to get a mirror finish polish is essentially zero.
if you bang it, it will chip and show a rough surface.
something like a bbs or ssr or rays will dent and if torn show a smooth shiny surface.
not only are their make ups different (there are literally thousands of alloy variants) but the way they respond to heat treating dependent on nickel contents and the likes will vary greatly.
