dymalloy is a really neat thing
it's an alloy of 20% copper, 80% silver, and <1% tiny diamonds dispersed through it
It's absurdly expensive but it also has among the highest thermal conductivity of anything workable at over 400 W/m·K, even higher than pure copper
it's about ½ to ⅓ as conductive as pure diamond but a) pure diamond is orders of magnitude more absurdly expensive than dymalloy and b) it's not workable, you can't machine it

@Felthry holup diamond is conductive???
@Nine diamond is, unless we're mistaken, the most thermally conductive thing known, up to 1300 W/m·K
it has the uncommon property of being highly thermally conductive while also being very electrically insulative, which makes it really useful for heatsinks if it wasn't so expensive

@Nine There are other minerals that are highly thermally conductive and electrically insulative too, like beryllium oxide (*oof* though, that's something you want to avoid using whenever possible due to its extreme toxicity) and boron arsenide (actually less dangerous than beryllium oxide but still bad), though the latter is a semiconductor and also extremely hard to get good crystals of
