What is the common name for these wheels?

Cheap plating is cheap and not usually long lasting. Good plating (triple plated - Cu, Ni, Cr) is pretty expensive but very durable and long-lasting, more upfront, but usually worth it in the long run.

So did one of the previous owners have them chromed? Or is it a factory option?
