Abstract
Improvements introduced in the manufacture of metallic plates for anodes of electronic valves that have a thickness of 100 microns, consisting of iron or an iron alloy that are re covered on one side with a dark-colored aluminum alloy and on the other side with a copper layer characterized in that the copper layer is applied with a thickness between 5 and 15 microns.
