Al,
Your local ACE hardware store (or the equivalent) probably has a display =
from K&S Engineering of small brass & aluminum tubes, angles, and bars =
for hobby purposes. Just the ticket!

Subject: RE: REFLECTOR:Buss material
Thanks for info on buss material. I thought there might be a =
corrosion issue on aluminum. I know there is an issue of fatigue =
failure as well in wires, which wouldn't be in a buss.
Aluminum is at least a good conductor; resistance about 1.6 times that =
of copper. Brass, on the other hand, has resistance about 4 times that =
of copper. The 1/8" x =BD" copper I had I got from Aeroelectric; I was =
surprised to find that he is now selling .025 thick brass instead. In a =
=BD" width, that's equivalent to about a #15 wire. Seems pretty =
marginal for a buss with half dozen or more circuits running off. The =
copper was equal to about a #2 wire. 1/8" brass would be great - now =
where will I get that on Sunday. . . .=20
Who's selling copper buss?? I have some .040 wall copper pipe laying =
around. I could cut and flatten that. =BD" wide would be about a #7 =
wire. That would handle it.
If you DO decide to go with Aluminum, how about sending the Copper to =
me.=20
I promise I will give it a GOOD home .... Jim S.
Sorry, Jim; no copper coming your way. I used most of what I had on =
ground busses. Considered the aluminum because I hate having to go =
show parts when I'm in the middle of a job.

Al,
Just the usual concerns with aluminum conductors. A little light =
corrosion in an aluminum connection has a lot of resistance, whereas a =
little light corrosion on copper adds only slight resistance. Extra =
resistance causes heat, which accelerates corrosion. A vicious circle. =
Therefore, you need to make extra certain you do what you can to prevent =
corrosion at the connections to an aluminum buss. Special coatings, =
etc. On balance, I don't think it's worth it - I'd get some more =
copper!

I had some 1/8" copper buss material that I used most of for ground =
buss. Any reason not to use 1/8" aluminum for circuit breaker buss?
