90-platinum 10-iridium vs. Tungsten Carbide
90-platinum 10-iridium and tungsten carbide belong to fundamentally different material chemistries. 90-platinum 10-iridium is a metal, while tungsten carbide is a ceramic material. 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 (12, in this case) are not shown.
For each property being compared, the top bar is 90-platinum 10-iridium and the bottom bar is tungsten carbide.
