Carbide - Wikipedia
Chemical classifiion of carbides Carbides can be generally classified by the chemical bonds type as follows: (i) salt-like (ionic), (ii) covalent compounds, (iii) interstitial compounds, and (iv) "intermediate" transition metal carbides. Examples include calcium carbide (CaC 2), silicon carbide (SiC), tungsten carbide (WC; often called, simply, carbide when referring to machine tooling

Zirc vs. Ceramic Both grains are considered “Hi-Performance”. Both will remove metal faster and last longer than all aluminum oxide or silicon carbide products. These Hi-Performance grains have the ability to constantly resharpen as they wear, providing fast cutting
Hardness varies but all cemented carbides are harder than the hardest metals. Tungsten carbide with a Vickers nuer of 1700-2400 (85 HRC equivalent) is composed of 90% carbide particles by weight, 80% by volume. Most standard wear resistant alloys
Vanadium Vs Other Carbide Formers | BladeForums
17/7/2018· Not quite as hard as vanadium, but the WC (tungsten carbide) can be cut with silicon carbide stones, especially if SiC is all you have and you want a more refined edge. CPM M4 is one of my favorites. A nice coo of alloying. 1.4Carbon 4.0Vanadium 5.5Tungsten 5.2Moly 4.0Chromium The wear resistance will come primarily from the vanadium carbide content, while the moly and tungsten …
