This document compares the performance of enameled aluminum wire and enameled copper wire. Some key differences include aluminum wire having lower tensile strength, higher resistivity, and lower melting point than copper wire. These differences impact the design of electric machinery, specifically the diameter selection and motor wire groove design. The differences also impact the method of removing paint from the wires, as special removers or chemicals are needed for aluminum wire versus copper wire. The attended mode and winding process must also account for aluminum's lower tensile strength.
