Soda-lime Glass vs. 6151 Aluminum
Soda-lime glass and 6151 aluminum belong to fundamentally different material chemistries. Soda-lime glass is a ceramic material, while 6151 aluminum 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 (20, in this case) are not shown.
For each property being compared, the top bar is soda-lime glass and the bottom bar is 6151 aluminum.
