Gold (2.44x10-8 Ω•m) is worse than copper (1.68x10-8 Ω•m), but better than aluminium (2.82x10-8 Ω•m).
It does have excellent anti-corrosion properties.
I wonder what kinds of alloys we will see in the potential future with asteroid mining and thus comparatively cheap gold.
Imagine replacing lead with gold in industrial applications.
Or the stainless steels with a gold component in them.
The trouble with asteroid mining is that getting anything there and back is expensive, let alone any heavy equipment needed for large scale mining.
My guess is the main application will be for space missions that find it cheaper to carry mining/manufacturing equipment rather than all the materials they need. Even that seems potentially a ways off. I suppose we could mine asteroids for science sooner, but that's quite a bit different than any mission plan which includes mining as a part of the required logistics. Maybe if there's some materials needed for extending life support capabilities? But still I'd have to wonder why not just take the extra supplies with you.
Maybe a moon or Mars base could change some calculus. As I suspect the break even point of such a plan may require lots of use of any such equipment.
