ScotchBrite does not contain metals. It does have some kind of ceramic or
ceramic-like material, though.  If it had metals it would never find use in,
say, cleaning equipment where metal is a destructive contaminant. It is used to
clean carbon/graphite, silicic (aka fused silica or "quartz"), alumina and
beryllia parts which must not have any metal contamination, etc. It still works
in sulfuric, which would quickly dissolve any metals in it (save for a few very
expensive ones). Dropped a whole pad in sulfuric peroxide once or twice and
nothing happened--nothing different, that is. Drop metal in it and the stuff
boils even more insanely.

There's something like 8 grades, ranging from ultra fine to extremely coarse.
I've used the common red, 7447 type (IIRC), the gray 7446(?) and the baby blue
super fine stuff. The baby blue stuff is so fine that it doesn't seem to work
even as a polish. Doesn't scratch VCR fitting glands--all the other grades do.
It is used on utra-super-high-precision tools and machinery. I haven't used the
gray stuff in a long time; don't remember how it does relative to the common red
stuff.
