For the most part, they are cast iron. However, the part that pokes out, and what the bearings ride on, is a separate, pressed in, piece. It could very well be, and likely is, Steel.

Re: 3rd gen spindle-what material?
When I cut my caliper mounts off to install an aftermarket brake system, it looked like steel to me. Cast iron can be easily broken from a sharp hit. Drop a cast crankshaft of camshaft on the floor and it can break since they are cast iron. Hit a spindle very hard with a hammer and it will bend before it breaks.

Nodular Iron is used for automotive castings. A stonger material then normal gray iron castings.
