I must assume that you are talking about Pb95/Sn5 and Pb10/Sn10.  Some
conventions always place the tin first and other place the major element
first.  Different countries use different conventions.  A good reference is J-
Std- 006 which for Pb95/Sn5 gives the solidus temperature at 208'C and the
liquidus temperature at 212'C, and for 90Pb/10Sn the liquidus temperature is
275'C and solidus temperature is 302'C.
