Rims N Brakes

I bought some fibrax replacement break pads, but didn't read the small
print. It says they're for alloy rims. Now, I've tried google, but
can't find if my rims are alloy or not. They feel lighter than the
wheels on my other bike.
Perhaps someone here knows what Mavic T224s are made of?

They'll be alloy, as in aluminium alloy.

And if not
alloy, what would be the consequences of using the wrong pads?

Inferior braking, possibly. There are special pads for ceramic coated
rims and steel rims, but ordinary pads can also work with steel, at least.
Shiny silver-coloured metal won't be ceramic.

Use a magnet to test for steel. If it sticks it's steel. (Lack of
noticeable attraction doesn't necessarily mean a metal is not steel, by
the way).

Steel rims are fortunately now rare. Fundamentally, it's not a problem
with _your_ brake pads; no brakes work at all well with steel rims in
the wet. If a magnet sticks to your rim, it's steel. Likewise, if
there's any rust on it, it's steel. But it's very unlikely unless your
bike was very cheap and nasty or unless it's more than ten years old.

I don't believe Mavic have ever sold a steel rim. Certainly, a T224 is
aluminium.

Thanks folks, I'll stop worrying, and worry about stopping.
