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.
