Who can calculate the meltingpoint for me of a mixture of metals with 40% Sn and 60% Pb?
Euhh, I have no clue what that means :) The substance I am asking for is soudage (a complete foreign word to me, I had to look it up in a dictionary)Originally posted by Bystander
From first principles? Or, did you just want a value for the Sn-Pb eutectic?

Ah! Thank you Bystander :)
But why is the eutectic temperature so much lower than the melting temperatures of the individual metals,
and why is my little calculation so far off?
Pb mp = 372.5
Sn mp = 231.9
40/60 Sn/Pb eutectic temp 183-238
