Is this wire worth anything? 8-3 Aluminum 70 feet

~30 to 90 cents per pound, stripped, depending where you are and how much of a crook you're dealing with... You might get more $ for it intact from someone needing it but the trick is finding them :) Everyone is paranoid about aluminum wiring even though it's a better conductor than copper. Phone a local scrap yard for a price (before you strip it) as some prefer to strip their own.

Perhaps it is a better conductor, but its heat properties are no where near as good as copper. It also gets very brittle and cracks. Trying to make connections after a couple years gets very difficult.

Copper is a much better conducter than aluminum. Al has about 64% the conductivity of copper.

Silver 63.01 =D7 10^6 Copper 59.6 =D7 10^6 Annealed Copper 58.0 =D7 10^6 Aluminum 37.8 =D7 10^6

Not so! That's why for the same ampacity, aluminum is called out at larger sizes than copper.

Oops, my bad lol. Aluminum is roughly double the conductivity by WEIGHT. Hence why it is used for overhead transmission lines.

Thanks for the correction Bill :)

Guess I'll put it up on Craig's List for $70 ($1 per foot) and see if anybody wants it.
