ABSTRACT:
An inlead for an electric lamp formed of an alloy of tungsten and molybdenum. The inlead has a rate of thermal expansion or contraction approximating that of the glass forming the bulb. This minimizes the expansion/contraction mis-match stress between the two materials. In addition, the alloy composition functions to reduce oxidation and degradation of the lead.
