Tungsten Carbide vs. GM-120 Glass Ceramic

Tungsten carbide belongs to the non-oxide engineering ceramics classification, while GM-120 glass ceramic belongs to the glass and glass-ceramics. There are 8 material properties with values for both materials. Properties with values for just one material (13, 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 tungsten carbide and the bottom bar is GM-120 glass ceramic.
