Hi All,
I am looking for a web purchase of 24 & 35 AWG ideally Teflon insulated hookup wire, if not other insulations are also welcome.
Thanks folks !

Teflon coated wire is the only type of hookup wire that is used in the F-15 aircraft...A little trivia. I would prefer to use it.I have not seen any with aluminum conductor though.Usually it is silver coated copper. The teflon is a little more difficult to strip off . I used a electric wire stripper when I was in the "Force" and working on avionics equipment.
there is a guy on eBay selling surplus navy wire in various sized and lengths. all teflon and silver coated copper.
I have been thinking of buyings some for various amp projects.
he has 30ga to 10ga from what i have seen.

Hi,
is the weight saving of significance to your proposed use?
Copper is about three times heavier but about 60% of resistance.
There is a significant weight saving when the cross-section is adjusted to match voltage loss (resistance). However the fatter aluminium conductor will run a little cooler.
How are you planning to connect the aluminium, you can forget all the conventional copper type fixings. Solder does not work and wire wrap doesn't either. A mechanical fixing must cut through the insulating oxide surface and the gas tight joint must stop all future oxidation. The mechanical deformation will reduce the fatigue life at the joint and may lead to premature cracking and failure.
Which grade of aluminium will you be using?
You'll gather that unless you are flying, or in some competitive motorsports' arena then I do not recommend aluminium.

I believe JSA just assumed the silver coated copper was aluminum. Or Im giving him the benefit of the doubt.🙂

No Sir, I was wishing to have pure insulated aluminium wire...if possible.....though I am losing hope right now !!
You are aware that aluminum oxide (the layer that forms on outside due to exposure to oxygen) is used as a dielectric....? i.e. it doesn't conduct....for long
I think makeing thin alu wire is a problem in the sense that it is brittle and can't be stretched into thiner and thinner wires like copper is...

Aluminum ? So much for doubt. Guess I stand corrected. LOL Cause I.m going to have to agree with Andrew and Nordic.I wouldnt waste my time with aluminum.
Guys you are right bad idea ! I wished to expriment on a JPS Lab clone.......
Back to the drawing board I guess !!
Thanks for all your inputs !

If you want exotic wire, I get the bare Cardas silver from Michael Percy, and teflon sleeving to fit. Sounds good, solders well, costs.
The reviews on silver coated copper are variable. Apparently some is heavily coated, some barely coated; some apparently sounds vile, some very good. So I just avoid the whole thing, and use the solid silver.

You shouldn't be paying much more than the market price of silver (about $200/kg).
Why waste money on Cardas when you can buy soft tempered fine silver wire from a jeweler?
Do you cut the legs of electronics parts ultra-short so there is less signal path through copper? Did you wind your transformer with silver? Your mains cable? If you use PCBs instead of point to point, is it silver instead of copper PCB?

This only makes sense for high frequencies due to the skin effect. For audio frequencies, the aluminum core will be doing most of the conducting since it's the bulk of the cross-section.
