Metalic Films

back to overview

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.


Metal

 
 Resistivity (10-8 m) Temperature coefficient (per C) Melting point
Aluminum (Al) 2,7 0,00429 660
Chromium (Cr) 13 0,003 1875 +/- 20
Copper (Cu) 1,7 0,0068 1083
Gold (Au) 2,2 0,0083 1064
Indium (In) 8,37 - 156
Nickel (Ni) 7,8 0,0069 1453
Platinum (Pt) 10,6 0,0039 1772
Silver (Ag) 1,6 0,0061 962

If the resistance is very important, it should be determined experimentally with the four point probe method.
