Amalgam is an alloy of mercury with other metals. So the answer is : mercury reacts with other metals to form an amalgam.

An amalgam is a substance formed by the reaction of mercury with another metal. Almost all metals can form amalgams with mercury, notable exceptions being iron and platinum.

An alloy of mercury with another metal (usually silver) used by dentists to fill cavities in teeth; except for iron and platinum all metals dissolve in mercury and chemists refer to the resulting mercury mixtures as amalgams.

Mercury is the only metal which forms amalgams with other metals. Ex: zinc amalgam.
