engine head construction
(OP)
I recently replaced the cracked head of my Saturn. I had not taken a good look at it before. It looks like it is made of aluminum styrofoam - lots of little beads all brazed together.
Does anyone know what manufacturing process this is and how do they make it?

The 'beads' you see are replicas of the plastic beads in the original foam. The metal underneath them is quite solid.
