Soda-lime Glass vs. Grade 28 Titanium
Soda-lime glass and grade 28 titanium belong to fundamentally different material chemistries. Soda-lime glass is a ceramic material, while grade 28 titanium is a metal. Therefore, their performance will be even more dissimilar than would be suggested by the difference in properties. There are 15 material properties with values for both materials. Properties with values for just one material (21, in this case) are not shown.
For each property being compared, the top bar is soda-lime glass and the bottom bar is grade 28 titanium.
