This specification covers round, zinc-aluminum mischmetal (Zn-5Al-MM) alloy-coated, steel core wire with three classes of this coating used for mechanical reinforcement in the manufacture of aluminum conductors, steel reinforced. The base metal shall be steel produced by the open-hearth, electric furnace, or basic oxygen process. The steel shall conform to the required chemical composition carbon, manganese, phosphorus, sulfur and silicon. The coated steel core wire shall conform to the required tensile and elongation properties. The wire shall be capable of being wrapped in a close helix around a cylindrical mandrel. For the purpose of calculating mass per unit length, cross sections, etc, the density of the material shall be taken. Wire diamter, mass and permissible variations shall be measured.
