ASTM A356 Grade 1 vs. Soda-lime Glass

ASTM A356 grade 1 and soda-lime glass belong to fundamentally different material chemistries. ASTM A356 grade 1 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. 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 ASTM A356 grade 1 and the bottom bar is soda-lime glass.
