WTF are cylinders made of?

[NugShee]

Ok guys, I have done a ton of polishing aluminum in the past few years but never done a set of banshee cylinders. I just started them and did a little spot to see how they are going to turn out. Got a shine out of them but they look more like steal then aluminum. They have almost a black chrome look instead of the traditional chrome finish. I also noticed that they seem much harder then normal 6061 aluminum. These cylinders are off of a 2001 Banshee. Am I just trippen or are these things cast Iron. MeatHead, Help me out. Thanks in advance guys.

The cylinders are cast aluminum with a cast iron sleeve pressed into them.
