Grade 704C Zirconium vs. ASTM B541 Gold

Both grade 704C zirconium and ASTM B541 gold are otherwise unclassified metals. There are 17 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 grade 704C zirconium and the bottom bar is ASTM B541 gold.
