Best Answer

Standard Romex is a three-strand, solid core wire, individually insulated, in a common sheath to make it easier to pull. For a short time, some manufacturers were making romex with aluminum because the cost of copper was so high, but the aluminum wire was not as good as the copper, and the practice was discontinued.
