Paul, having been away for  a while I am curious.  Has anyone explored AMMC?  It is molten
aluminum mixed with ceramic whiskers.  It is said the the aluminum serves the same purose as
plastic matrix.  The resulting composite is much stronger than either of the base materials
separately and exhibits a trememdous strength to weight ratio.  Used in the Corvette as a torque
tube and driveshaft?  Sounds interesting.

Sounds great. Is it lower density than aluminum? If so I will tell
my foundry about it. If it pours the same with  equal viscosity
as molten aluminum it might save some weight on these low stress
sand casting.
