I am seeking for some about TRUE melting temperatures of
metals and their alloys. Im intrested in silver and its alloys. The
problem is that I have seen many diffrent melting temperatures in
many sources. And I am mad about it!
In Tim McCreight book Practical Casting he says:
-Fine silver 961C/1762F
-Sterling silver 920C/1640F
-Coin silver(reticulation silver) 890C/1634F
The first problem is that when I convert *F to *C
-Sterling silver 920C should be 1688F and 1640F should be 893C
So which on is TRUE melting temp?
If it is 920*C then *F temp is wrong. It *F temp is correct that *C
temp is wrong. But if F temp is correct than it means sterling
melts at 893C and that is totally stupid because it cant have only
3 degree higher melting temp then coin silver!
Other way is that coin silver can have wrong temp here in this book.
Coin sivler is 80/20 and its melting temp is 890C?? Then how it is
possible that eutectic alloy of silver 71,9/28,9 can have melting
Ok enough of this. Please, can someone give me RIGHT melting
temperatures of these silver alloys?
