Chromium

Chromium can be used as a conductor, but it is not as conductive as some of the other metals. It is often used as a adhesion metal in thin films, between the ceramic substrate and the gold traces. Without this element, the 1950's would not have been possible!

All values except melting point are assumed to be at 25 degrees C, and may vary dramatically over temperature.
