Tungten Carbide Crystal Structure and Physical Properties
Strength - Tungsten carbide shows compressive strength that is higher than virtually all melted and cast or forged metals and alloys.
Rigidity/Hardness - Tungsten carbide is two to three times as rigid as steel, and four to six times as rigid as cast iron and brass. Young's Modulus is up to 94,800,000 psi, second to diamond.
Impact Resistant/TRS - Tungsten carbide cemented alloy shows high transverse rupture strength (TRS) that is in par with hardened tool steels.
Heat Resistance - Tungsten-base carbides perform well up to about 1000°F in oxidizing atmospheres, and to 1500°F in non- oxidizing atmospheres. Up to 1400°F, tungsten carbide retains much of its room temperature hardness. At 1400°F, some grades exhibit a hardness of steels at room temperature.
Cold (Cryogenic) Resistance - Tungsten carbide retains toughness and impact strength in the cryogenic temperature ranges up to -453 °F.
Thermal Conductivity - Tungsten carbide conducts heat twice as fast as alloy tool steel and carbon steel.
Electrical Conductivity - Tungsten carbide has an electrical resistivity comprarble to that of alloy tool steel and carbon steel.
Specific Heat - Tungsten carbide shows a specific heat that is about 50% to 70% higher than that of carbon steel.
Density - tungsten carbide has a very high density, which is 1-1/2 to 2 times that of carbon steel.
Magnetism - Nickel binder cemented alloys has negligible magnetism. Cobalt binder cemented alloys shows low ferro-magnetism.
