7010 Aluminum vs. Grade 36 Titanium

7010 aluminum belongs to the aluminum alloys classification, while grade 36 titanium belongs to the titanium alloys. There are 25 material properties with values for both materials. Properties with values for just one material (5, 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 7010 aluminum and the bottom bar is grade 36 titanium.
