Is tungsten carbide a hard metal?
Accordingly, is tungsten carbide harder than steel?
Yes, tungsten is harder than steel in the fact it is very difficult to scratch. Tungsten carbide (meaning hard metal, widia, WC-Co, not a pure carbide which is a technical ceramic) is intrinsically fragile and has little or no plasticity.
Furthermore, which is harder tungsten carbide or cobalt? Scratch Resistance: While cobalt is harder than titanium, and therefore more scratch resistant, tungsten is still the hardest metal currently on the market. In simple terms, although cobalt and tungsten are both extremely hard metals, a tungsten ring will have a higher resistance to scratching.
Similarly, why is tungsten carbide so hard?
It's most striking properties are a high density and a high melting point of 2600 °C, a high hardness as well as the metal-like, high values of electric and thermal conductivity. The WC grid causes a certain plasticity and high breaking ductility while maintaining the high hardness of tungsten carbide.
