I would hang on to it. I have the occasional need to make bus-bar "bugs",
and other high-current connectors and contacts.

Last year, I had to make all new rheostat studs for my very (very) old EZ-GO
golf cart. They'd discontinued the part.

Nothin' for it but copper rod, lathe time, and some frustration getting my
rake angles right.

(single-point threading of copper is a pain in the ass!)

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?
