ASTM B596 Au-Cu vs. C78200 Nickel Silver

ASTM B596 Au-Cu belongs to the otherwise unclassified metals classification, while C78200 nickel silver belongs to the copper alloys. There are 19 material properties with values for both materials. Properties with values for just one material (12, 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 B596 Au-Cu and the bottom bar is C78200 nickel silver.
