Tungsten Carbide vs. C14500 Copper
Tungsten carbide and C14500 copper belong to fundamentally different material chemistries. Tungsten carbide is a ceramic material, while C14500 copper is a metal. Therefore, their performance will be even more dissimilar than would be suggested by the difference in properties. There are 14 material properties with values for both materials. Properties with values for just one material (21, in this case) are not shown.
For each property being compared, the top bar is tungsten carbide and the bottom bar is C14500 copper.
