ASTM B541 Gold vs. EN 1.8870 Steel

ASTM B541 gold belongs to the otherwise unclassified metals classification, while EN 1.8870 steel belongs to the iron alloys. There are 22 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 B541 gold and the bottom bar is EN 1.8870 steel.
