ASTM B780 Alloy vs. Grade Ti-Pd17 Titanium
ASTM B780 alloy belongs to the otherwise unclassified metals classification, while grade Ti-Pd17 titanium 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 ASTM B780 alloy and the bottom bar is grade Ti-Pd17 titanium.
