Abstract
An electric lamp construction is described having a pair of conductive inlead wires of dispersion-strengthened copper alloy to serve as the sole means of physical support for a resistive incandescent filament electrically connected thereto, wherein said inlead wires have a surface metallurgical structure of fibrous dispersion-strengthened copper alloy. Said metallurgical surface of the inlead wires can further serve to enhance bonding of other materials thereto including metals such as nickel and aluminum as well as nonmetallic gettering materials such as phosphorous compounds.
