Eutectic
eutectic a mixture of two or more elements which has a lower melting point than any of its constituents. Typical usage: eutectic alloys for soldering in the electronic industry, composed of tin (Sn), lead (Pb) and sometimes silver (Ag).Former text (to be included) A eutectic is an alloy with a well-defined melting point. A non-eutectic alloy, when it freezes, crystallizes first one part and then another; a eutectic does not separate when it freezes. The graph of melting point versus concentration bends at the eutectic, usually with the eutectic being a minimum.
