Cole,
Not a lot of cast iron done with this bunch but zinc-aluminum alloys machine
like cast iron (which is very good) yet the stuff melts at a lower
temperature than pure aluminum. You may want to do a search for "ZA".
If a casting breaks, I would melt it down and cast another rather than weld
it. As for attaching castings together, fasteners and pins work well. Some
use epoxy which seems to hold better than fasteners as long as you never
want to take it apart.
Not sure why you would want to forge it since you can cast its shape.
As for melting cast iron - very high temperatures done with a special
furnace. Not something I would do alone.

And no cast-iron... I've tried welding it and it explodes, I've tried
forging it and it shatters, I don't even want to find out what it does when
you melt it.
