ABSTRACT:
There is provided a core element, especially useful in fabricating an electrically heatable catalytic converter, which element comprises a thin stainless steel strip having an area on at least one surface coated with a masking alloy, especially a nickel-containing brazing alloy, and a contiguous area coated with a refractory metal oxide, e.g., alumina. This structure enables the production of catalytic cores exhibiting minimum voltage drop at the interconnections between foil laminae to be heated electrically.
