Is there a significance diff between mod construction materials? Copper for the least reduction in voltage? Brass always seems more expensive that SS? Anything compelling to consider?
Best material for a mod?

no sorry, its actually silver (1.59×10−8), copper (1.68×10−8), gold (2.44×10−8), plat (1.06×10−7) in that order
if all you care about is conductivity, the answer is copper, silver is too soft, expensive, has corrosion issues and is only slightly more conductive than copper

My list is the order I WOULD prefer. Gold and Platinum don't have near the oxidation maintenance that Silver does.
Yes if you're looking for lowest voltage drop go with copper. Preferably with a hybrid top cap as in the XXIX. There is no positive pin so even less voltage drop. Actually no voltage drop down to .2 and down to .08 there is only a .004 drop. And it does make a difference. I was using my old chi you before I got the XXIX and had to build a higher ohm coil because it was too hot on the XXIX.
You left out Aluminum that slots in right after gold and is about 3 times as conductive.
The problem with most of them is that they form oxides that are insulators, or at least worse conductors. With the size of the mod body there is really no problem with just about any of them. Try to cut down on connections, 1 piece tubes, I have seen a new mod that has a button that is part of the tube and not screwed on. Something like Noalox will improve conductivity at the joints, it has zinc particles that will cut through the oxide layer.
Whatever you use keep the places where it contacts clear of any oxidation. Silver is a great conductor but tarnished silver is not. I have seen Rhodium used as a plating because it does not oxidize easily.
Titanium does not scratch as easily. Copper and brass are easier on the tools used to make them. I would really like Tungsten carbide cause it is nearly impossible to scratch.

I think I sparked more of a scientific debate vs. a practical one. I guess I meant to imply that I was sticking within the materials that mech mods are being produced these days: Brass, SS, Copper are really all I see, more or less within reason. If someone out there makes a solid gold mod, be sure to send me a link, i'll go ahead and order a few I think I got an answer of copper though...which is what I suspected.
Thanks all!

This diamond mod is only $800,000
You know, you can have a mod plated. You might want to re-do the thread though if the plating is too thick.
If you're going through all that, you'd want gold though.
1) Resale value
2) Bling
3) Bling
4) Low oxidation
5) Bling
Although I could see making some parts silver or copper for contrast.
Seriously, this is why circuit board connectors are gold plated. Good connections for parts with little tarnish/oxidation.
I think you could debate the ground pin on the button though. Since they are often sanded....copper or brass or whatever.

If you do a Rhodium(?) coating on a silver plated contact, you wont have oxidation issues. my nemesis has silver plated contacts and its a year and a half with no tarnish ^^
That's pretty good but I suspect the plating is not pure silver.
