why two high melting temperature metals are getting melt earlier or mean at very low temperature after mixing.

Ex :- Tin (sn) - 231 C melting point lead (pb) - 327 C melting point

But Sn/Pb - 63/37 melting temperature is 183 C

Thermodynamically, alloying increases free energy & entropy. You are basically adding disorder to the lattice by alloying so it is easier to melt. [Laxmi Narayanan R, Practical Metallurgist!!!!!]
