Unfortunately, nothing's really said about the metal they're made of particularly, but it's the best source I could find.

Hard for me to say how to summarize them. In the case of, say, MCU Quicksilver, I guess the best I could suggest would be to focus on the biggest moments (getting his powers, his initial motive and allegiance, then the change into a hero). Specifics like him leading to Hawkeye being wounded early in the movie, going back home, then fighting the Avengers can be left out.
