There's a vein of some key metal called ithilmar, but it's also an alloy:
Article: Under its steam-clad slopes can be found the world's sole vein of the metal known as Ithilmar...
...Ithilmar can only be forged with the addition of other mineral ores found uniquely on the slopes of the Dragonspine Mountains.
So at the least whatever properties the finished metal exhibits should be something to do with the alloy. That or the metal has those properties but it's literally impossible to work without those other minerals, which might make more sense actually.
