what is better to use?

I normally use copper, but I can get my hands on the following
Titanium
steel
stainless steel
brass
copper
bronze
Aluminum

we use copper wire, so imo copper bars would be the logical choice.

First choice Copper, second choice aluminum.
If its subject to the elements or battery acid, do aluminum or shield from the batts.

Αctually the first choice should be gold second silver but i guess they're too expensive ,so i go for third best .... copper

Aluminium?Does it really work?

I've posted this many times before (maybe I should make it a sticky?)

Resistivity_____Conductivity_________Metal
1.591E-08______6.287E+07 ______Silver, Pure
1.664E-08______6.009E+07 ______Copper, Pure
2.463E-08______4.060E+07 ______Gold, Pure
2.826E-08______3.538E+07 ______Aluminum, Pure
3.918E-08______2.552E+07 ______Bronze, Commercial (Annealed)
4.660E-08______2.146E+07 ______Brass, Red (Annealed)
6.158E-08______1.624E+07 ______Cartridge Brass (Annealed)

[Resistivity = ohms/m, Conductivity = SIEMENS/m]

1.0m = 3.281ft

Copper or Aluminum are the most economical choices.

Damn... well I picked up a steel bar the other day from HD.

Should I bring it back and get aluminum instead? Is steel really that bad?

Yes, get aluminum. Steel is quite far down on "the list"

Resistivity_____Conductivity_________Metal
1.611E-07______6.206E+06 _______Steel, Cast
6.897E-07______1.450E+06 _______Steel, 304 Stainless
7.184E-07______1.392E+06 _______Steel, 347 Stainless

what about 110 copper electrical grade

aluminum is cheaper then copper. ALOT cheaper. Wondering about silver plated copper bars also.

I can get longer length and 3 bars for what it costs for 1 copper bar.

Regardless if you get copper or aluminum, just make sure it isnt a cheap alloy. Nickel is sometimes mixed with copper which significantly reduces the conductivity.

Ie:

Resistivity_____Conductivity_________Metal
6.386E-08______1.566E+07 _______Aluminum Alloy, 380
3.831E-07______2.610E+06 _______Nickel 30%, Copper 70%

i think your forgot about platinum but sense most people cant even afford a platinum necklace i dont see as its worth even talkin about

oh yeah and iridium but i think thats even more then platinum, there are places using these things but mostly in circuit boards and the gains for us would not be helpful.

anyone thought about using water inside a controled enviornment, pure water consisting of no minerials the the best insulation where as water consisting of minerials or tap water or any water basically is a conductive.

I saw a gain when switching from alimunum bar to copper bar of the same width and thickness. Way more expensive but louder.
