Key Differences
Tungsten Carbide and Boron Carbide are both incredibly hard materials, but they hail from different elemental backgrounds and have distinct applications. Dive into their specifics, and the contrasts become evident.
Tungsten Carbide, often denoted as WC, is a chemical compound containing equal parts of tungsten and carbon atoms. In its raw form, it's a fine powder, but when pressed and sintered, it becomes extremely hard, rivaling diamonds. This hardness makes Tungsten Carbide invaluable in the manufacture of industrial machinery and cutting tools. On the contrary, Boron Carbide, represented as B₄C, is one of the hardest materials on earth, coming third after diamond and cubic boron nitride.
While Tungsten Carbide's primary claim to fame is its use in cutting, drilling, and mining tools due to its sturdiness and resistance to wear, Boron Carbide takes a different route. B₄C's unique attributes make it ideal for body armor, bulletproof vests, and even tank armor. This is because, besides being hard, it's also relatively lightweight.
Another noteworthy application of Boron Carbide is in nuclear reactors. Its ability to absorb neutrons makes it useful for this purpose. Conversely, Tungsten Carbide is frequently used in jewelry, particularly in men's wedding bands, as it's resistant to scratching.
