No the voltage doesn't take a hit of ... and then go party all over the body of any mod and then, somehow through blind luck, find your addy and light it up. LOL WTH are you talking about! If it did that and since you are a ground, you'd feel a lil bit of electrical charge in your fingers. It doesn't happen because the electricity is taking the path of least resistance. And the whole mod is not the path of least resistance nor is your body that path. The pin is that path. And if you're feeling a.1 volt difference in your vape. well dude you have one very sensitive set of nerves. 4.2v down to 4.1v I have never felt a difference in my vape nor seen it in a blown cloud. And I doubt you notice that .1v either until maybe around 3.5 from 3.6v.
Each type of metal has a different conductivity. Even within each type of conductive metal, there are different blends of those particular metals to enhance or diminish the amount of conductivity it may have. Hence why on my brass mods, they either have a copper or silver plated pin. I won't buy a brass mod with a bass pin in it. Why! Because if (like in some clones) the manufacturer uses the same brass the mech is made of in the pin, then we could indeed have an ... party and then electricity could start to party all over the brass, since the whole thing is made of all the same metal with the same conductive amount. Especially too if the pins aren't isolated with some sort of no conductive amterial to stop the party before it starts. No! what has happened I think, really is that once those screw in readers came out to the market with their built in resister ( the one in mine was a .5 ohm resister) people started seeing that result of the built in resister on their battery when placed on top of their mod and decided OH NO! MY MECH has a voltage drop! No it doesn't. But your reader certainly will read less voltage then what your battery has in it simply because like your addy, it has a resister in it. Kanthal and nichrome wire is called.... (drum roll please) RESISTANCE WIRE. Resistance will drop the voltage because it tries to slow down the electrons. It resists the speed of the electrons, thereby through friction caused by it, heats the resistance coil up. Anyway. I've yet to read with any mult-meter (and I have two, my cousin one, which I also used to check with, 3 neighbors who had them that I borrowed just to make sure nothing was wrong with mine and to see if any one of them would give me any different results) any substantial difference to start crying wolf about mechs having built in volt drop to them.
Yes Op, different metals do have different conductive abilities and within each metal type, (as I stated before) there are blends of them to make them more conductive and less. Silver is the most conductive, then copper , then Gold, Aluminum, Zink Nickel, iron and the list goes on. Best place to find your answer would be to goggle "10 most conductive metals"
