Description of ASTM-B327 2016ASTM B327-16Historical Standard: Standard Specification for Master Alloys Used in Making Zinc Die Casting AlloysASTM B327Scope 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.
(A) Carried to one additional decimal place to ensure proper control in the final alloy.
(B) ASTM alloy designations were established in accordance with Practice B275.
(C) ASTM Specification B6, for Zinc.
(A) Zinc-base master alloys V12-3 (Z33730) and V12-5 (Z35740) used for producing die casting alloys may contain
nickel, chromium, silicon, and manganese up to 0.02, 0.02, 0.035 and 0.05 %, respectively. No harmful effects have ever been noted due to the presence of these elements in up to these
concentrations in die casting alloys and, therefore, analyses are not required for these elements, except that nickel analysis is required when producing die casting alloy Z33526.
(B) The UNS assignations were established in accordance with Practice E527.
(C) For purposes of determining conformance with this specification, the observed value or calculated value
obtained from analysis shall be rounded off “to the nearest unit” in the last right hand place of figures used in expressing the specified limit, in accordance with the rounding method of
Practice E29.
(D) Refer to Practice B908. (Note: Color Codes indicated are for North American applications.)
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.
(A) Jumbo ingots outside the above weight limits may be acceptable depending upon the chemistry, if mutually
agreed upon between the producer and purchaser.
(B) ASTM alloy designations were established in accordance with Practice B275.
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 Safety Data Sheet (SDS) 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.
