Dear Lon,

A Eutectic Alloy is best visualised on a phase diagram. It is the mixture of
metals which gives the lowest melting point.

See the Tin/Lead phase diagram attatched with the 183 C (61.9% Sn) eutectic
point marked on it. The triangles to the left and right of this point are
the 'pasty' phases which have already been referred to in other postings.

Hope this helps.
