For silver, values of mechanical properties are given from a paper by McKeown and Hudson (Ref. 130), and from NBS Circular 101 (Ref. 133) and NBS Circular 412 (Ref. 15). Rockwell hardness (B and F) and tensile strength versus percent reduction (0 % to 68 %) by rolling are plotted for “fine” and Sterling silver. Plots tensile strength versus temperature for “fine” and Sterling silver and silver alloys from 78 °F to 1200 °F.
