Silicon carbide is the hardest of the conventional abrasives but has lower impact resistance than aluminium oxide and shows a higher wear rate when used for grinding steels. Silicon carbide wears more rapidly when used to grind metals that have an affinity for carbon such as iron and nickel. It is therefore used primarily for nonferrous materials.
Silicon CarbideGreen is typically used for grinding, polishing, lapping, ceramics, refractory, heating elements and for electrical uses. Bayville''s Silicon CarbideGreen powder is produced in an electrical resistance furnace from quartz sand, petroleum coke and salt at extremely high temperature.

Tungsten carbide is approximately four times stiffer than steel, with a Young''s modulus of approximately 550 GPa,[1] and is much denser than steel or titanium. It is comparable with corundum (aAl2O3) in hardness and can only be polished and finished with diamond wheels and compounds. Tungsten Carbide Powder Chemical Name: Tungsten carbide
Tungsten Carbide Powder Once mixed with cobalt and binder, tungsten carbide is pressed and sintered. Sintered tungsten carbide is one of the hardest substances known to man, and is used to cut steel, drill circuit boards and a multitude of other high tech applications in the automobile and aerospace industries, and beyond.
Tungsten carbide (chemical formula: WC) is a chemical compound (specifically, a carbide) containing equal parts of tungsten and carbon atoms. In its most basic form, tungsten carbide is a fine gray powder, but it can be pressed and formed into shapes through a process called sintering for use in industrial machinery, cutting tools, abrasives, armorpiercing rounds, other tools and instruments ...

The extreme hardness of silicon carbide makes it an excellent material for abrasive wear applications. Silicon Carbide Production. Silicon carbide shapes, formed from submicron powder, are sintered at temperatures in excess of 2000°C resulting in a finegrain silicon carbide component that is extremely pure with nearly zero porosity.
Mar 11, 2019· Industrial silicon carbide is light yellow, green, blue or even black due to the type and content of impurities contained in it. The transparency varies with its purity. The crystal structure of silicon carbide is divided into hexagonal or rhombohedral αSiC and cubic βSiC (called cubic silicon carbide). Since αSiC constitutes many ...

SILICON CARBIDE BALLS Silicon Carbide Balls are very highcost grinding media that are used for milling same materials (silicon carbide ball to mill silicon carbide materials) to avoid contamination. They are only available in 5mm,10mm, 15mm and 20mm sizes. They are a special order item.
Tungsten Carbide is a gray powder. It is often mixed with Nickel and Cobalt to make cemented Tungsten Carbide which is used in tools for machinery and metal cutting, and rock drills. REASON FOR CITATION * Tungsten Carbide is on the Hazardous Substance List because it is cited by ACGIH and NIOSH. * Definitions are provided on page 5.
As with sludge, the heavier your powder, the higher the carbide content. Tungsten powder is used in processes like thermal spray for hardfacing and other processes; so if your scrap comes from a process that began with tungsten powder, it will have a higher tungsten content and thus be more valuable. How to Identify Carbide
