Sure - it's a classic engineering tradeoff - if you look at a dollars

copper to get the same resistance, but copper costs a lot more than
60% more than aluminum. So if you've got room, it's cheaper to make it
When costing copper vs aluminum: for a given VOLUME of metal (which is
what we are talking about here) we have to use both the price per
pound of the respective metals AND the density of the respective metals.
That works out to something like 10:1 in favor of aluminum vs copper.

Very much so. If Aluminum weren't such a pain to make good connections
to, it would almost always be the preferred material.
Like I say, with the money you save, buy a TIG welder and develop a new
skill. Or at least that's what you'll tell people.
