Grade 5 Titanium vs. Grade A Lava

Grade 5 titanium and grade A lava belong to fundamentally different material chemistries. Grade 5 titanium is a metal, while grade A lava is a ceramic material. Therefore, their performance will be even more dissimilar than would be suggested by the difference in properties. There are 9 material properties with values for both materials. Properties with values for just one material (29, in this case) are not shown.

For each property being compared, the top bar is grade 5 titanium and the bottom bar is grade A lava.
