Tungsten Carbide | Density, Strength, Hardness, Melting Point
Melting point of Tungsten Carbide is 2867 °C. Note that, these points are associated with the standard atmospheric pressure. In general, melting is a phase change of a substance from the solid to the liquid phase. The melting point of a substance is the temperature at which this phase change occurs. The melting point also defines a condition ...
Tungsten Carbide – Wissensplattform nanopartikel.info
Tungsten Carbide. Tungsten carbide is a hard metal and used in wear-resistant ceramics due to its exceptional hardness and stability, e.g. for the manufacturing of nozzles or tools. By adding metals like cobalt, iron or nickel to the tungsten carbide other hard metals are being generated with tungsten carbide-cobalt being one example.
