Rockwell Hardness - an overview ScienceDirect Topics

WebIt is approximately two times stiffer than steel and double the density of steel. It’s hardness and resistance to heat are what make it an ideal material for cutting tools. Other applications benefit from its high density, which is comparable to gold and uranium and is almost twice that of gold. Other Tungsten Uses Tungsten carbide has a high melting point at 2,870 °C (3,140 K), a boiling point of 6,000 °C (6,270 K) when under a pressure equivalent to 1 standard atmosphere (101.325 kilopascals), a thermal conductivity of 110 W·m ·K , and a coefficient of thermal expansion of 5.5 µm·m ·K . Tungsten carbide is extremely hard, ranking about 9 to 9.5 on the Mohs scale, and with a Vickers number of around 2600.
