Zinc die casting alloys require high metal purity in all
applications. Therefore, they are made only from high-purity
(99.990%) primary zinc. The mines and smelters that supply the
zinc used by North American die casters do not generally operate
at full capacity. Zinc is used in a variety of industries,
including corrosion protection for steel (galvanizing). The broad
use of zinc and the margin in production capacity contribute to a
stable supply of the metal for zinc and ZA die casting alloys.
Zinc and ZA alloys are produced and distributed by smelters and
alloyers dispersed internationally.
