Re: [TCML] aluminum magnet wire
Hi Jim, yep, agree with regards to a "secondary" coil! Here is a Javatc
look at a loaded 5" x 22" coil and the main parameters affected between
copper and aluminum.
Secondary Coil Inputs:
5" x 22", 900T, 24Awg, 6.25" x 21" toroid:
DCR Cu DCR Al
30.1 Ohms 48.1 Ohms
ACR Cu ACR Al
95.7 Ohms 152.7 Ohms
Q Cu Q Al
Sure, the unloaded Q of the secondary is 2/3 (as expected.. Al
conductivity is about 2/3 that of Cu).. but since the loaded Q of a TC
is around 10, clearly most of the losses are elsewhere.
