Class 3 Tungsten vs. ASTM A732 Cast Steel

Class 3 tungsten belongs to the otherwise unclassified metals classification, while ASTM A732 cast steel belongs to the iron alloys. There are 24 material properties with values for both materials. Properties with values for just one material (7, in this case) are not shown.

For each property being compared, the top bar is class 3 tungsten and the bottom bar is ASTM A732 cast steel.
