Copper mod hits harder than SS

Conductivity is not important at all. Resistance is important. If resistance of SS mod is less than 0.01 ohm, is it important?

EDIT: I have to say that I calculated resistance of SS mod 100 mm long, 22 mm diameter with walls 2 mm thick. I got it's resistance equal to 0.005 ohm. I do not guarantee quality of my calculations (they are simple, but...) So, I welcome possible corrections.

You're calculating on a solid mass though... Remember there are lots of connections which are imparting their own resistance. And I suspect you'll see a much larger resistance in say a threaded connection that's copper to copper versus stainless to stainless.

Not really; I normally run a 2 ohm coil in my drippers (A7), and the v drop difference between my brass mods and SS mods is quite noticeable.

The question is: is the v drop difference between your brass mods and SS mods due to the main tube material, or is it really mostly due to the contact points like the switch and center pin materials.

For example
- if you have a steel nemesis and a copper nemesis, and
- you swap around the parts to make a steel tube nemesis with copper topcap and bottom switch
- and a copper tube nemesis with steel topcap and bottom switch

how's the v drop difference between the two going to go?

Brass/silver contacts

SS/silver contacts

So a 0.12 difference
AW IMR 18490 (16a) 4.11v, A7 2.08 ohms

So I've seen a few posts on this thread on voltage drops so I figure I'd show my version of what I've been seeing as far as my copper nemmy vs my SS king. I used the same atty with a 0.32 ohm dual coil build. I also used the same battery in both mechs. Sorry I don't have any pics to show so you'll just have to take my word for it lol. Maybe later I'll take some pics. Used my VTC 4 or 5 not sure and it wasn't fully charged as well, but it was the same battery and atty so I really don't think that makes a difference when comparing mech mods. I also used an in-line volt meter if you happen to care about that as well.
The results:

dirty copper nemesis with copper contacts that hasn't been cleaned in about a week; .32 volt drop.

Freshly cleaned SS king with silver plated contacts; .72 volt drop

Some people have said to test with a 1ohm build but I don't vape @ 1ohm. I might, if I ever get me a VV/VW mod that goes higher than 30 watts but until then, I'm sticking with my warm and dense vape @0.32 ohms on a mech. I didn't do this to see if my copper mech had a 0.12 voltage drop, I did it because I felt that my SS wasn't hitting as hard as my copper nemmy.

My conclusion:
The Numbers never lie, so I can't understand how some people say that copper and SS mods hit the same and that it's all in my head. If it was then the numbers would come out the same or close to it anyways.
I'm not an electrical engineer or a mod maker so I could be wrong and I could have done the volt drop test the wrong way (I highly doubt it). But I do know this... My copper mod hits harder than my SS mod

Recently "went copper" with a Vapetech Pegasus clone. I'm loving it! Hits plenty hard, looks cool with a patina (imo), and I haven't really noticed an odor on my hands.
