Tungsten carbide is approximately three times harder than steel (the most hardness of tungsten carbide may be more than 93HRA), with a Young''s modulus of approximately 550 GPa, and is much denser than steel or titanium.
Silicon Carbide: The Return of an Old Friend | Sigma …
Silicon carbide is harder, yet more brittle, than other abrasives such as aluminum oxide (Prod. Nos. 202606, 342750). Because the grains fracture readily and maintain a sharp cutting action, silicon carbide abrasives are usually used for grinding hard, low tensile-strength materials such as chilled iron, marble, and granite, and materials that need sharp cutting action such as fiber, rubber
Super Hard Ceramics – They don’t get much tougher | …
Boron Carbide, for instance, is currently the hardest material produced in tonnage quantities and is the third hardest material known to man after diamond and cubic boron nitride. Not far behind it in the hardness stakes comes silicon carbide, more commonly known as carborundum, steeped in history since it was first mass-produced in 1893 and probably the most common of all industrial abrasives.
