Scope

1.1 This specification covers aluminum–base and zinc–base master alloys used to make zinc die-casting alloys. Alloy compositions specified for aluminum–base master alloys (hardeners) are designated as shown in Table 1. Alloy compositions specified for the zinc-base master alloys are designated as shown in Table 2.

1.2 Aluminum alloy hardeners are added to Special High Grade zinc (per Specification B6) in the proper alloying ratios, as shown in Table 1, to produce zinc alloys for die casting.

1.3 Zinc-base master alloy is added to Special High Grade zinc (per Specification B6) in the proper alloying ratio, as shown in Table 3, to produce zinc alloy for die casting.

1.4 Master alloys may be supplied in the form of shot, bar, ingot or jumbo ingot as specified by the purchaser.

1.5 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.

1.6 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to become familiar with all hazards including those identified in the appropriate Material Safety Data Sheet (MSDS) for this product/material as provided by the manufacturer, to establish appropriate safety and health practices, and determine the applicability of regulatory limitations prior to use.
