Last year I bought some aluminum wire in coils like you describe. I
think it was a company
in Ohio and may very well have been Malinco. Anyway, they had a 50 lb
minimum and charged
something like $3 and change per pound. This is way cheaper than
McMaster. I wholeheartedly
agree that alloy 1100 is the hot setup. BTW, did you know it also is
the most corrosion resistant?
The stuff I got was annealed to practically wet noodle consistency :-).
Wonderful to work with.
