Abstract
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.
Scope
1.1 This specification covers round, high strength, zinc–5 % aluminum-mischmetal (Zn–5Al–MM) alloy-coated, steel core wire with one class of Zn–5Al–MM coating (MA3) for use in overhead electrical conductors.
1.2 This specification covers wire of diameter from 0.0500 to 0.1900 in. inclusive or 1.27 to 4.82 mm inclusive.
1.3 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard.
