ABSTRACT:
A metallic sheet for an electronic housing having a zinc coating on a steel base and a thin metal film, preferably a copper film, covering the zinc coating on one or both sides of the sheet, and a method of making the metal film. The metal film reduces whiskering of the zinc in the zinc coating. Whiskering can also be prevented on other metals anodic to copper such as, for example, tin and cadmium.
