Grade 15 Titanium vs. C93800 Bronze

Grade 15 titanium belongs to the titanium alloys classification, while C93800 bronze belongs to the copper alloys. There are 28 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 15 titanium and the bottom bar is C93800 bronze.
