If calcium is a metal, can it be used for things like electric circuits? Can it be smithed?

I just found out it was a metal.

Calcium has a conductivity that's a bit worse than aluminum, so it would be OK for electric circuits if it weren't so reactive. It corrodes quickly in the presence of air or water into calcium compounds that are no longer conductive.
