surfaces. 3M boron carbide has a much higher hardness (Mohs 9.5+) than tungsten carbide (WC), titanium carbide (TiC), aluminum oxide (Al 2 O 3), zirconium oxide (ZrO) and silicon carbide (SiC). This high hardness allows fast and easy machining of wear
Diamond v. Carbide : Weighing the Costs and Benefits | …
Below is an example of a cost comparison using a diamond saw blade versus a carbide tipped blade: $.0028/$.0143 = PCD costs 19.6% of carbide when comparing $/Linear Foot (80.4% cost reduction) Another advantage of PCD tooling, apart from the longer tool life, includes the quality of finish which is often significantly improved and therefore requires less sanding.
Panadyne Inc.: Green Silicon Carbide
Silicon Carbide is produced by heating silica sand and a carbon source, typically petroleum coke, to high temperatures in a large, open “Acheson” furnace. The result of this high temperature process is the crystalline formation of Silicon Carbide grains, of both Green and Black coloring.

The Designer’s guiDe To TungsTen CarbiDe
Tungsten carbide powder, generally ranging in proportion between 70%-97% of the total weight, is mixed with a binder metal, usually cobalt or nickel, compacted in a die and then sintered in a furnace. The term “cemented” refers to the tungsten carbide particles
Grades - General Carbide
Tungsten carbide (WC), also referred to as cemented carbide, is a composite material manufactured by a process called powder metallurgy. Tungsten carbide powder, generally ranging in proportion between 70%-97% of the total weight, is mixed with a binder metal, usually cobalt or nickel, compacted in a die and then sintered in a furnace.
How is Tungsten Carbide Formed? | Chronicle
The process to coine tungsten metal with carbon to form tungsten carbide (abbrev.WC) can be accomplished several different ways. One method to create the powder that is unique to Kennametal is by a chemical reaction using extremely high temperatures – greater than 2,200 °C – generated from burning aluminum to react tungsten with carbon.
Silicon Carbide SiC Material Properties - Accuratus
Silicon carbide ceramics with little or no grain boundary impurities maintain their strength to very high temperatures, approaching 1600 C with no strength loss. Chemical purity, resistance to chemical attack at temperature, and strength retention at high temperatures has made this material very popular as wafer tray supports and paddles in semiconductor furnaces.
