Answer 1

All combinations of different metals form alloys. An alloy composed by mercury and other metal is an amalgam. In dentistry, amalgams may be composed by 3, 4, 5 or even more elements, so they are called binary, ternary, etc. Traditional dental amalgams contain Mercury, Silver, Copper, Tin and sometimes Zinc. Other metals like Palladium or Indium have been added by a few manufacturers, to modify the physical properties of the alloy.
