That won't work. No copper wire of any reasonable thickness will work. You 
won't find what you want in any common household device that I can think of. I 
should be able to measure the wire sometime and calculate the conductivity and 
maybe find out what it is, but you can start off by measuring the resistance 
for 1 foot of the wire you're considering. If it's not 100 Ohms, +/- 20%, it 
won't be any good.

A copper wire in that size will still probably have less than 1 Ohm per foot 
resistance, and it will be too soft to stand up to the float sliding up and 
down it for long. 40AWG copper wire would have 115 Ohms/ft, so that would be 
close, but it is only .003" dia.

Is the original wire magnetic, by any chance? Try a magnet on it.
