Organization: ASTM International
Publication Date: 1 October 2015
Status: inactive
Page Count: 3
ICS Code (Lead, zinc, tin and their alloys): 77.120.60
scope:

1.1 This specification covers zinc master alloys which are used in hot dip galvanizing for the purpose of adjusting the concentration of certain alloying elements in the molten zinc bath. Table 1 covers the chemical composition of these materials which include six master alloys of zinc-aluminum (brightener) and one master alloy of zinc-antimony.

   ASTM   Common    UNS
  Type A-1 90/10 Zn/Al High Purity Z30750
  Type A-2 90/10 Zn/Al Low Purity Z31710
  Type A-3 95/5  Zn/Al High Purity Z30503
  Type A-4 95/5  Zn/Al Low Purity Z31510
  Type A-5 96/4  Zn/Al High Purity Z31520
  Type A-6 96/4  Zn/Al Low Purity Z30504
  Type S-1 90/10 Zn/Sb   Z55710

(A) The following applies to all specified limits in this table: For purposes of determining conformance with this specification, an observed value obtained from analysis shall be rounded off to the nearest unit in the last right-hand place of figures used in expressing the limiting value, in accordance with the rounding method of Practice E29.(B) UNS numbers in conformance with Practice E527.(C) Chemical method under development.(D) For information only. Quantitative determination of this element is not required. Zinc is assumed to be the difference between 100 % and the sum of those elements listed above.

Note 1: The master alloys in Specification B860 are intended to be used primarily in hot-dip galvanizing to adjust the concentration of certain elements in a molten zinc bath, and differ from the zinc-aluminum alloys in Specification B997 which are intended to be used primarily in molten zinc-aluminum.

1.2 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.

1.3 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.
