steel is azterä (revisited)

azterä = steel (metal alloy) (noun) (some things Google found for "aztera": an uncommon to rare term; Aztera LLC is a technology company in product development in Tucson, Arizona; Aztera Marketing of New Zealand; a rare last name; user names; name of a World of Warcraft character)

Word derivation for "steel":
Basque = altzairu, Finnish = teräs
Miresua = azterä

My previous Miresua word for steel was azteri. This is a small change, a tweak.
