ABSTRACT:
A process for bonding a copper or nickel end junction piece to an aluminum electrical conductor wire. The copper or nickel end junction piece is used to make the electrical connection with terminals in meters, fuse boxes, switches and the like, thus eliminating such junctions with the aluminum wire and hence eliminating the possibility of the formation an aluminum oxide connection which may give rise to overheating and subsequent fire. The end junction pieces may be applied on-site after the aluminum wire is cut to the desired length. No special pretreatment of the aluminum wire end is necessary prior to the addition on the end junction piece.
