A390.0 Aluminum vs. Soda-lime Glass
A390.0 aluminum and soda-lime glass belong to fundamentally different material chemistries. A390.0 aluminum is a metal, while soda-lime glass is a ceramic material. 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 (20, in this case) are not shown.
For each property being compared, the top bar is A390.0 aluminum and the bottom bar is soda-lime glass.
