Tungsten carbide is a hard and dense metal with a high melting point that is formed by combining or alloying carbon with tungsten. Tungsten carbide is a deep gray color when untreated, but it can be polished, sandblasted, or carved to achieve a variety of finishing aesthetics. The best tungsten carbide rings contain at least 80% tungsten.

Tungsten Carbide (WC) is a tough, high-density ceramic often used in severe service applications. Tungsten carbides are commonly known for use in high-quality tooling inserts.

At concentrations above the NIOSH REL, or where there is no REL, at any detectable concentration: (APF = 10,000) Any self-contained breathing apparatus that has a full facepiece and is operated in a pressure-demand or other positive-pressure mode. (APF = 10,000) Any supplied-air respirator ...

That doesn't seem like much difference, but together with cobalt's greater heat resistance, it supports higher cutting speeds—depending on the brand and whether the drill is coated, this might mean 50% faster spindle RPM and commensurately higher feedrates. ... That brings us to tungsten carbide, more commonly referred to as carbide …

Thermal Conductivity. 121 W/m·K. Coefficient of Thermal Expansion (α L) 6.9×10 -6 1/°C. Electrical Properties. Metric. Magnetic Susceptibility. 0.00001 cm 3 /mol. Note: unless stated otherwise, all values are taken at room temperature (approximately 20°C or 68°F) and 1 atm pressure. (1 atm = 101,325 Pa)

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 ...

Material: Zirconium Nitride (ZrN) is a hard ceramic material used as a coating on carbide burr bits. Properties: ZrN coatings offer high hardness, abrasion resistance, and can withstand high temperatures. This coating reduces friction, which in turn reduces heat generation during cutting. It also provides a lubricating effect.
