Hi all, i have the machining handbooks for milling, lathe, and advance work. Book example. In those books everything is metric numbers and also has types of material I've never heard of except for cast iron. Has anyone heard of these and can tell me what type of material it is or one of the easier ways to maybe find this material? Perhaps even substitutions for it.

Also another question i have is i am making a spindle for a dividing head and i was curious if cast iron would be ok for that? I know i am making a ER20 collet head for my lathe out of cast iron so i would just like opinions.
