I guess I disagree with this one statement, above.  Every alloy, I am aware
of, melts at a lower temperature than that  of the highest-melting
constituent, pure element.  IIRC, this is because the atoms of different
elements cannot be packed, in a crystalline structure, as densely as ones
that are of all the same size.

Pure copper (Cu) melts at 1981 degrees F.  Pure zinc (Zn) melts at 786
degrees F.  A brass alloy comprised of 85% Cu and 15% Zn has a listed
melting point of 1652-1724 degrees F.  I'm not certain why this specific
composition has a range, rather than a specific melting point.  I'm quite
certain that the higher the ratio of zinc to copper, the lower the M.P. of
the resulting brass alloy.
