Commercially Pure Silver vs. ASTM B817 Type II

Commercially pure silver belongs to the otherwise unclassified metals classification, while ASTM B817 type II belongs to the titanium alloys. There are 16 material properties with values for both materials. Properties with values for just one material (15, in this case) are not shown. Please note that the two materials have significantly dissimilar densities. This means that additional care is required when interpreting the data, because some material properties are based on units of mass, while others are based on units of area or volume.

For each property being compared, the top bar is commercially pure silver and the bottom bar is ASTM B817 type II.
