Rather like platinum, Minas. But stronger. Anything that doesn't react and is fairly shiny anyway would be a contender, but the specified strength is akin to that of titanium (which is too heavy, so an aluminium alloy fixes that).

And Ed, what else are we to take information from if not the real world? Mithril by such standards cannot alloy with steel, compare to Aramir's half-arsed "but it's silver" argument.
