Need to confirm paint code for factory f10 M Sport wheels

[nuck]

I have a 2012 550i with the M Sport 19s. I suspect there aren't a lot of different factory wheel colors but I don't know where to go to confirm for sure. I have found paint code A80 Ferric Grey Metallic for sale but not reference to specific years. Has anyone done this? wheel.jpg

Also what are the wheels made of? Are they two piece aluminum and steel? The curb rash looks like aluminum because no oxidization at the edges but I have what looks like rust blistering about to bust through on a couple of spots (see pic). Surprising these things are starting to rot at 40k miles. My E39 had painted alloys as well and the wheels were perfect when I sold it at 75k.

Thanks for any responses

Looks like Ferric Grey ll which was a new color for the 2012 MY. BMW code B 55 but the touch up I found on Ebay called it Ferric Grey ll B44. The A80 Ferric Grey is an earlier wheel paint color.
