1.1 This specification covers soft, medium, and hard temper zinc-5% aluminum-mischmetal (Zn-5 Al-MM) alloy-coated carbon steel wire in coils for general use. The product is intended for applications requiring corrosion resistance, drawability, and formability.

1.2 This specification is applicable to orders in either inch-pound units (as A856) or acceptable SI units [as A856M]. Inch-pound units and SI units are not necessarily equivalent.

1.3 The supplementary requirements of this specification cover Zn-5 Al-MM alloy coating weights for nails, staples, and wire from which nails and staples are cut and formed.


This specification covers soft, medium and hard temper zinc-5% aluminum-mischmetal alloy-coated carbon steel wire in coils for general use. The product is intended for applications requiring corrosion resistance, drawability, and formability. The wire is classified with regard to mechanical properties by temper, which is related to tensile strength and stiffness. Zn-5AL-MM alloy coating on the wire is classified in a number of classes: 1, 3 or A, 60, B, 100, and C. The steel from which the wire is produced shall be made by any commercially accepted steelmaking process. The tensile strength of the coated wire shall be determined and the weight and adherence of the coatings shall be measured.
