Copper 510 cente pin???

[dannler]

So i was browsing trough all the rda's on fast tech and saw most of the guys complains about the 510 pin being copper? They always want stainless steel.... Can anyone explain to me why? And is there such a big difference

Copper is a much better electrical conductor than ss but it would tend to oxidise there because of juice leaking on to it.

So i just need to clean it more often?

i clean mine with paper towel every time i refill. Some atomizers leak more than others. ...i'm just wondering, ejuice - PG/VG, probably prevents oxidation?
But ja, i know from flashlights, from cpf forum, any oxidation, even when it's not visible, causes slight voltage drop. i suppose it's not significant with vapemods, but...
