This specification covers aluminum-base and zinc-base master alloys used to make zinc die-casting alloys. The material may be made by any suitable process. The material covered by this specification shall be of uniform quality and shall be free of dross, flux, or other harmful contamination. If the material is in shot form, it shall be sound, uniform size, and free of a heavily oxidized surface coating, stringers, and moisture. Aluminum-base master alloys (hardeners) shall be tested and conform to the required chemical composition for aluminum, copper, iron, silicon, manganese, magnesium, zinc, chromium, nickel, tin, lead, and cadmium. Zinc-base master alloys shall conform to the color code requirements and to the required alloy composition for aluminum, magnesium, iron, copper, lead, cadmium, tin, and zinc. The weight of jumbo ingots shall conform to the required weight limits.

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.
