Grade 18 Titanium vs. EN 2.4964 Cobalt

Grade 18 titanium belongs to the titanium alloys classification, while EN 2.4964 cobalt belongs to the cobalt alloys. There are 27 material properties with values for both materials. Properties with values for just one material (3, 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 18 titanium and the bottom bar is EN 2.4964 cobalt.
