Traditionally, the Greek and Roman god of the dead is associated with gold and silver, since he controls everything under the earth: he has epithets like Plūtōn "the [god] of riches" and Dīs Pater "the wealthy father".
But does this extend to other metals? In particular, does any classical author specifically associate Hades with iron, bronze, or other useful (rather than ornamental) metals? Or are those the dominion of a different god? Greek and Latin answers are both acceptable.
(This question is inspired by the recent Broadway musical Hadestown, which calls the lord of the underworld "king of iron, king of steel".)
