RE: [TCML] Copper vs. Aluminum/Steel wire for the secondary coil?

["Richard Schmuke" <rdj@xxxxxxxxxxxx>]

Alum wire has a different, whiter, lighter color than SS or Ti and is
lighter than both. If you think it might be Ti , take a short piece and hold
it to a sander or grinder , white sparks it is Ti , colored sparks indicate
a ferrous  metal , if it just leave a white deposit (no sparks) it is likely
to be alum. You can take a short piece and flex it, Ti is springy , alum not
hold up as well.

Subject: [TCML] Copper vs. Aluminum/Steel wire for the secondary coil?


 

Thanks to those who have helped with recent questions 

 

I was rummaging through my trunk and found that last summer I got a very
good deal at the MIT flea market, 8 and a half pounds of aluminum (at least
I think its aluminum) wire for about 10 bucks.  It appears to be #26 gague
and in new condition, still has the cellophane wrapped around the
circumfrence save for a bit that the original owner used.

 

If I were to use this on a secondary coil form, how would the numbers crunch
differently in terms of inductance, frequency, resistance, self capacitance
etc?  I know the performance would not likely be as good as copper, as it is
not as good of a conductor ... 


also I am guessing on it being aluminum, i don't think its steel as it does
not react to an fairly strong magnet.
