This specification covers three types of zinc-aluminum (Zn-Al) alloys in ingot form for re-melting for use in the production of hot-dip coatings on steel: Type 5 (95/5 Zn/Al), Type 10 (90/10 Zn/Al), and Type 15 (85/15 Zn/Al). Requirements prescribed by this specification cover ordering information; chemical, physical, and mechanical requirements; sampling for determination of chemical composition; methods for chemical analysis; material and manufacturing requirements; dimensions, mass, shapes, and sizes; workmanship, finish, and appearance; inspection and certification; product and package marking; and packaging and preparation for delivery.

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

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 establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
