Why is Silicon Carbide Used in Semiconductors
Silicon Carbide, sometimes mistakenly referred to by the trade name Carborundum. Silicon Carbide is widely used in the manufacture of heating elements, slide bearings, sealing rings, wear parts, sintering aids, crucibles, burner nozzles, heat exchangers. Silicon Carbide also has the resistivity necessary to perform as a semiconductor material.
What is Tungsten Carbide or Hard Metal?
Tungsten Carbide is often referred to as a Hard Metal due to it’s very high hardness in relation to other metals. Typically a Tungsten Carbide Hard Metal can have a hardness value of 1600 HV, whereas mild steel would be in the region of 160 HV a factor of 10 lower.

Tungsten Carbide has a high melting point, 2,870 C (5,200 F), is also extremely hard ( Vickers hardness nuer = 2242) and has a low electrical resistivity (~2×10−7 Ohm•m), compared to other metals (e.g. vanadium 2×10−7 Ohm•m). Rockwell Hardness
Tungsten Carbide vs. Titanium - IQS Newsroom
Tungsten Carbide rings are considered a better choice compared to Titanium rings because the superior hardness levels of Tungsten Carbide makes the ring virtually unscratchable. Newer alloys involving tungsten carbide and nickel-silicon-boron mixtures have recently hit the market and these innovations have been proven to offer superior abrasion resistance in appliions involving oil and gas
