Anotation

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.
