Why is cast iron a good material for radiators? Why not another metal?
Would certainly make them a little lighter and easier to deal with.

Aluminum might be better, but wasn't around when cast-iron radiators
were first made. Iron is an excellent metal for casting and conducts
heat well (and is less expensive than other metals, like copper, that
are better conductors).
