Malleability an overview ScienceDirect Topics

Gold is known mainly for its color, electrical conductivity, ductility, and corrosion resistance. The malleability of gold is the highest of all metals; 1.0 troy ounce can be spread to approximately 300 ft 2 of foil. Gold by itself is not strong enough for many applications and must be alloyed.
