1.1This specification covers steel sheet, metallic-coated with zinc-5 % aluminum alloy via the hot dip process, in coils and cut lengths. The Zn-5Al alloy coating also contains small amounts of elements other than zinc and aluminum that are intended to improve processing and the characteristics of the coated product.

1.2The coating is produced as two types: zinc-5 % aluminum-mischmetal alloy (Type I) and zinc-5 % aluminum-0.1 % magnesium alloy (Type II), and in two coating structures (classes). The coated sheet is produced in several coating designations (coating weight [mass]) as shown in Table 1.

1.3The product is intended for applications requiring corrosion resistance, formability, and paintability.

1.4The product is available in a number of designations, grades, and classes in four general categories that are designed to be compatible with different application requirements.

1.4.1Steels with mandatory chemical requirements and typical mechanical properties.

1.4.2Steels with mandatory chemical requirements and mandatory mechanical properties.

1.4.3Steels with mandatory chemical requirements and mandatory mechanical properties that are achieved through solid-solution or bake hardening.

1.5The product furnished under this specification shall conform to the applicable requirements of the latest issue of Specification A924/A924M, unless otherwise provided herein.

1.6The text of this specification references notes and footnotes that provide explanatory material. These notes and footnotes, excluding tables and figures, shall not be considered as requirements of this specification.

1.7This specification is applicable to orders in either inch-pound units (as A875) or metric (SI) units [as A875M]. Values in inch-pound and SI units are not necessarily equivalent. Within the text, the SI units are shown in brackets. Each system shall be used independently of the other.

1.8Unless the order specifies the “M” specification designation (SI units), the material shall be furnished to inch-pound units.

1.9This 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

1.10This 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.
