The biggest issue with annealing brass is, its a GREAT conductor of electricity, and virtually non-magnetic.
While aluminum is non-magnetic, it's not so good at conducting electricity, so soldering or brazing aluminum is MUCH easier, even though brass & aluminum have similar characteristics.
Most of the common units were intended for soldering/brazing and that's what we get to work with...
An open 'O' or 'C' ferrite kicks these lower powered annealed up about 6 notches, and ferrite is cheap & easy to work with, just don't kink the tubing when winding!
(Freezing water in the tube before you wind is a sneaky shortcut)
