yes for corrosion resistance and ductility. no for hardness, electrical and heat conductivity. you can’t use gold or its compounds as catalysts where copper makes sense
Comment on Gold
Zwiebel@feddit.org 12 hours ago? Gold would be a big upgrade over copper

For what? Gold is a shit conductor compared to copper.

It’s not shit, it’s top 3 behind silver and copper. But those oxidize and gold doesn’t. So a gold coated silver core is what you want.

I stand corrected. Idk why I thought it was a better conductor

Gold coating for connectors is nice. For everything else it doesn’t really matter, you get an oxide layer that prevents further oxidation.

It has ~70% the conductivity of pure copper, it’s not “shit”

Would it? Perhaps it wouldn’t oxidise as fast, but copper is more conductive.
