1.1 This specification covers round, high strength, zinc-5 % aluminum-mischmetal (Zn-5A1-MM) alloy-coated, steel core wire with Class A Zn-5A1-MM alloy coating used for mechanical reinforcement in the manufacture of special aluminum and aluminum-alloy conductors, steel reinforced.

1.2 This specification covers wire of diameter from 0.0500 to 0.1900 in. inclusive.

1.3 The values stated in inch-pound units or SI units are to be regarded separately as standard. The values in each system are not exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in nonconformance with this specification.


This specification covers round, high-strength, zinc-aluminum-mischmetal (Zn-5Al-MM) alloy-coated, steel core wire with Class A Zn-5Al-MM alloy coating used for mechanical reinforcement in the manufacture of special aluminum and aluminum-alloy conductors, steel reinforced. The base metal shall be steel produced by the open-hearth, electric furnace, or basic oxygen process. The wire shall be cold drawn and coated with Zn-5Al-MM alloy to produce the desired properties. Chemical requirements of the steel, such as carbon, manganese, phosphorus, sulfur, and silicon shall meet the requirements prescribed in this specification. The Zn-5Al-MM-coated steel core wire shall conform to the tensile and elongation requirements. Test methods for tensile, wrap, coating and adherence shall be also be performed.
