Lead - Melting Points of Binary Eutectic Alloys

Pb - Lead (Plumbum) - binary eutectic alloys and melting points

The melting point of an alloy of two (binary) or more metals depends on the relative proportions of the ingredients. An eutectic mixture is the mixture at such proportions that the melting point is as low as possible.

Binary eutectic Lead - Pb - alloys, with composition and melting points are indicated below:

Alloy Component Weight of Alloy Component

Pr - Praseodymium 31 1315 1908
Pt - Platinum 5 563 554
Sb - Antimony (Stibium) 11 520 477
Sn - Tin (Stannum) 61 460 369
Te - Tellurium 78 680 765
Ti - Titanium 74 998 1337
  • T(oC) = 5/9[T(oF) - 32]
