Longely, Go to www.goodfellow.com and request their catalog CD. It
contains a fantastic reference of material properties. Silver is
listed, and so are most of the silver alloys.
Linear Expansion Coefficient at 0-100C for Silver 19.1 x 10 -6/K
(nineteen point one times ten to the minus six per Kelvin)
Other thermal properties listed:
Latent Heat of Evaporation>>>2390J/g
Latent Heat of Fusion>>>103J/g
Specific Heat at 25C>>>237J/K kg
Thermal Conductivity at 0-100C>>>429W/m K
Cheers!
