a·mal·gam

(ă-mal'gam),
An alloy of an element or a metal with mercury. In dentistry, primarily of two types: silver-tin alloy, containing small amounts of copper, zinc and perhaps other metal;, and a second type containing more copper (12%-30% by weight); amalgams are used in restoring teeth and making dies.

(15) The first major change in alloy for dental amalgam since the late 19th century occurred in 1963, when Innes and Youdelis (9) introduced the high copper amalgam alloys. This powder was made up of two types of particles: spherical Ag-Cu alloy particles and lathecut, irregular, low-copper Ag-Sn alloy particles.
