Abstract

A heating element appropriate for use with printed circuits and which is itself a printed circuit comprises a filament consisting of a mixture of aluminum and aluminum oxide, the resistivity of the heating element formed of the filament being adjustable by varying the thickness of the filament. The filament is supported on a ceramic coating on a metal substrate.
