1.1 This specification covers GALFAN, zinc-5 % aluminum-mischmetal (Zn-5Al-MM) alloy (UNS Z38510) in ingot form for remelting for use in the production of hot-dip coatings on steel. Alloy composition is specified in Table 1. 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 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. TABLE 1 GALFAN, Zn-5Al-MM Alloy Ingot Chemical Requirements A <(hoch),> B <(hoch),> C <(hoch),> D <(hoch),> E Element UNS Z38510 Composition,% Aluminum F 4.2 - 6.2 Cerium + lanthanum, total 0.03 - 0.10 Iron, max 0.075 Silicon, max 0.015 Lead G , max 0.005 Cadmium G , max 0.005 Tin G , max 0.002 Others H , each, max 0.02 Others H , total, max 0.04 Zinc Remainder A For purposes of acceptance and rejection, the observed value or calculated value obtained from analysis should be rounded to the nearest unit in the last right-hand place of figures, used in expressing the specified limit, in accordance with the rounding procedure prescribed in Section 3 of Practice E29 . B By agreement between purchaser and supplier, analysis may be required and limits established for elements or compounds not specified in the table of chemical composition. C GALFAN, Zn-5Al-MM alloy ingot for hot-dip coatings may contain antimony, copper, and magnesium in amounts of up to 0.002, 0.1, and 0.05 %, respectively. No harmful effects have ever been noted due ....(abbreviated)
