Abstract
A termination material for a vitreous enamel electrical resistor which includes a mixture of a glass frit and particles of nickel and iron. The termination material is applied to a substrate and fired to melt the glass frit, and then cooled to form a layer of the glass with particles of an alloy of nickel and iron embedded therein. The termination material may be applied to the substrate either before or after the resistance material is applied to the substrate.
