ASTM B617 Coin Silver vs. 2014 Aluminum

ASTM B617 coin silver belongs to the otherwise unclassified metals classification, while 2014 aluminum belongs to the aluminum alloys. There are 19 material properties with values for both materials. Properties with values for just one material (11, 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 ASTM B617 coin silver and the bottom bar is 2014 aluminum.
