Alpha Quartz vs. Monel 400

Alpha quartz and Monel 400 belong to fundamentally different material chemistries. Alpha quartz is a ceramic material, while Monel 400 is a metal. Therefore, their performance will be even more dissimilar than would be suggested by the difference in properties. There are 11 material properties with values for both materials. Properties with values for just one material (24, 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 alpha quartz and the bottom bar is Monel 400.
