History

Supermanium is apparently the hardest metal in the known universe; it is practically as indestructible as the Superman himself.

It was used in the construction of Superman's Supermobile, as well as a jail for Brainiac. According to Superman, he forged it out of the heart of a star[1], similar to how the Atom obtained his costume.
