1.2 This specification presents
requirements for zinc alloys suitable for the production of sand
cast or plaster cast forming dies for sheet metal stamping
operations and plastic injection molding. Alloy A is intended for
use in the fabrication of dies for sheet metal stamping under drop
hammer and hydraulic pressure. Alloy B is a special purpose alloy
of closely controlled composition and is primarily used in the
manufacture of plastic injection molds.
1.3 This specification covers two zinc alloys which are specified and designated as follows:
