For some special applicatioons sometimes an extremely thin (nobble) metal film is required. Sometimes, for the conductivity, sometimes for the reflection in other cases for catalytic purposes. Below you will find a table of the melting point and resistivity of various metals.
All values are obtained from: CRC Handbook of Chemistry and Physics, Robert, C. Weast, 1977-1978. 58th edition, CRC press, inc.
If the resistance is very important, it should be determined experimentally with the four point probe method.
