Metallic materials (metals and alloys) are generally good conductors; the best in descending order are:

-silver         " argento"
-copper;     "rame "
-gold;         " oro "
-chrome;   " cromo "
-iridium;    " iridio "
-tungsten; " tungsteno"
-nickel;       " niche "
-iron;           " ferro"

rubber "gomma"
plastic  "plastica"
