Graphite would probably be the most affordable of materials to use.  We had
a machinist in our local group at one point and he made a titanium nozzle
as a proof of concept.  That would more than likely be rather pricey for
this project ( his was for a 54mm motor).

Aluminum is a good material to practice on or do mockups with, but I
suspect that it's melting point is way too low to be used as the actual
nozzle.  It might work as a carrier for a graphite or ceramic insert though.
