1.1 This specification covers GALFAN, zinc-5 % aluminum-mischmetal (Zn-5Al-MM) alloy (UNS Z38510)3 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 Safety Data Sheet (SDS) for this product/material as provided by the manufacturer, to establish appropriate safety, health, and environmental practices, and determine the applicability of regulatory limitations prior to use.

1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.


This specification covers GALFAN, zinc-aluminum-mischmetal (Zn-5Al-MM) alloy (UNS Z38510) in ingot form for remelting for use in the production of hot-dip coatings on steel. The alloys may be made by any approved process and shall be free from dross, slag, or other harmful contamination. The alloys shall conform to the requirements as to chemical composition prescribed for aluminum, cerium and lanthanum, iron, silicon, lead, cadmium, tin, zinc, and other elements. Sampling for chemical analysis of the alloy in standard ingot form shall be done either by drilling, sawing, or melting, and shall meet the requirements specified for selection of portion, sample preparation, and size of sample and storage. Determination of the chemical composition shall be performed by ICP argon plasma spectrometric or other methods. X-ray fluorescence spectrometry may be used for determination of cerium and lanthanum.
