This specification covers annealed bare round copper-clad steel wire for the following applications: electrical, electronic, grounding, telecommunications, and other applications. Four types of copper-clad steel wires according to their electrical conductivities are included. The wire shall consist of a core of homogeneous open-hearth, electric-furnace, or basic-oxygen steel with a continuous outer cladding of copper thoroughly bonded to the core throughout. The copper-clad steel wire shall conform to the specified requirements for: tensile strength, elongation, dimension (diameter), adhesion and surface defects, joints, finish, copper thickness, density, and electrical resistivity. Methods for measurement, inspection, and testing such as torsion (twist) test are detailed.
