I’ll believe you I don’t kn9w about this stuff I think I sharpened a kitchen knife once and my dad was making me he said I did a bad job and I tried to use that knife later I think he was being too nice
i suppose i could duck it, but is gold more conductive than copper or silver? i thought gold was used because it resists oxidation but not because of its conductivity.
edit:
yeah so tldr my hunch was right. but they’re all pretty similar in conductivity.
yeah, after impact, quite evenly. last time it happened, it was called iridium anomaly. there’s not that much gold in electronics and other platinum group metals are more useful from material engineering perspective
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
or you can use slightly thicker copper. but sometimes you can’t, and that’s when silver is a slight upgrade
i heard that microwave parts for satellite use are made this way: first you start with aluminum, for structural and weight reasons. then it’s plated on inside (where microwaves are) with thin layer of zinc, then with copper. you can’t plate copper on aluminum directly. copper is there to conduct microwave current, but silver is even better, so there’s a layer of silver to conduct most of it, and copper handles the rest. then it’s topped with gold, but it’s a very thin layer, so thin that it doesn’t conduct a lot of current. it’s there only for corrosion resistance
At least everything would be covered in gold then. Electronics would be cheaper too.
They’d be cheaper to make.
Then we kill all the billionaires and then they’re cheaper to have
With gold bullets and a gold guillotine. I think they would like that.
Gold plated isn’t actually hard I think I could to that in my bathtub but would it hold an edge?
Best I can do is a can of krylon
Maybe the blade would have to be replaced on every use, but the weight would still do its job.
… actually, maybe the blade wouldn’t even need to be replaced.

There is no much specifically because it is expensive.
there’s not much because it can be plated real thin and more is not necessary
The accountant vs the engineer
? Gold would be a big upgrade over copper
Would it? Perhaps it wouldn’t oxidise as fast, but copper is more conductive.

For what? Gold is a shit conductor compared to copper.
You are wrong , Fry-man
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”
