Copper makes a nice Buss bar for common returns or earth ground.

I used big copper bars (1/4" thick) in my rectifier when I converted
my welder to Cubloc microcontroller and normal three phase rectifier:

Now, a 1" thick bar is a little bit too much for that!

I have a copper bar that I am deciding whether to keep it (1x2x15"). I
cannot think of any hobby style need that would involve a copper bar
like that. I have other bars that are more practicable, like
0.25x2x15, etc, these are quite useful for all sorts of things, such
as in my welder conversion, etc. But I cannot see any need for making
parts from big thick copper bars. Aluminum would always be cheaper,
have good electrical and thermal properties, and easier to machine.

Is that, in fact, true?
