Tungsten Carbide - High Precision Machining & Polishing
Tungsten carbide is approximately two times stiffer than steel, with a Young''s modulus of approximately 550 GPa, and is much denser than steel or titanium. It is comparable with corundum (α-Al 2 O 3 ) or sapphire/ruby in hardness and can only be polished and finished with abrasives of superior hardness such as cubic boron nitrideand diamond, in the form of powder, wheels, and compounds.
Thermo-mechanical properties of silicon carbide filled …
The effect of addition of silicon carbide (SiC) filler in different weight percentages on physical properties, mechanical properties, and thermal properties of chopped glass fiber-reinforced epoxy composites has been investigated. Physical and mechanical properties, i.e., hardness, tensile strength, flexural strength, interlaminar shear strength, and impact strength, are determined with the

Ceramic harder than carbide? | BladeForums
2016/5/19· As for hardness, tungsten carbide is measured in the Vickers scale, well beyond the range of the Rockwell C scale. If carbide is around 2,600 Vickers HV, think of it as roughly equivalent to 120Rc on the Rockwell scale.
Silicon Carbide. Silicon carbide is only next to diamond and boron carbide in hardness, and 95% harder than our standard alumina. It exhibits high thermal conductivity, high thermal -shock resistance, and strength durability at extreme temperatures. Silicon carbide has the highest
