Grade 11 Titanium vs. Grade CW12MW Nickel

Grade 11 titanium belongs to the titanium alloys classification, while grade CW12MW nickel belongs to the nickel alloys. There are 24 material properties with values for both materials. Properties with values for just one material (8, 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 11 titanium and the bottom bar is grade CW12MW nickel.
