They look all shinny like Alu to me. But I never took at magnet to one. I'll have to do that.

Btw... I would really stick with BMW rotors. I have learned the hard way that the OEM rotors just aren't made like OE (bmw) ones. The bmw rotors are pricey, but they don't warp like aftermarket ones do. This year I have put ATE and Bosch rotors on my heavy five series(e39) and now I am gonna put some OE bmw rotors on. The Autobahn isn't kind to brakes.
