Zinc is still an important metal. The amount of zinc produced and used
annually is behind only steel, copper and aluminum. About 75% of
it is used in galvanizing, but zinc alloys (Zamac) are still used in
some die casting. Zamac is readily available in billet form. Plenty
of die-cast zinc (alloy) objects can still be found in junkyards.
