Orichalcum?

I admit, most of what I know about this comes from the Indiana Jones IV - the Fate of Atlantis game, lol, so I'd like to know what you people think about this substance

Apologises if that topic has been done before

This is the Latin to English translation:
Definition:-

orichalcum - copper ore / brass.

Everything else I found pretty much said it was a brass alloy.

Indiana Jones and the Fate of Atlantis, what a great game. I had forgotten about it until you posted this.

Copper is said to be the metal of choice as weapon in 4d, I wonder if this is related?

by 4d, you mean 4th dimension?

Copper is one of the metals that make up brass. Maybe copper and something else made up Orichalcum, making it "brass-like", but not brass.
