Default Aluminum Hookup Wire

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.

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.

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.
