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.
Tungsten carbide provides a long-lasting, wear-resistant option and it is an extremely hard material, almost as hard as diamond. Tungsten carbide parts offer a better alternative in the case of industrial parts subject to wear. It can be used for machine parts that come in contact with very abrasive materials.
Carbide grades can also be classified by composition. Tungsten carbide (WC) grades can be divided into three basic types simple, microcrystalline and alloy. Simple grades consist primarily of tungsten carbide and cobalt binders, but may also contain small amounts of grain growth inhibitors. The microcrystalline grade consists of tungsten ...

May 11, 2021 Tungsten carbide is a very dense 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 for use in industrial machinery, cutting tools, abrasives, armor-piercing shells and jewellery. Its price is around 300 $/kg.
May 15, 2011 tungsten carbide is a ceramic and that makes it very brittle. The harder the material, the more brittle it is. the softer or more malleable the material, the less brittle it is. personally, I dont think tungsten carbide is a great material for luxury items. great for industrial purposes, but jewelry and watches, not so much.

Carbide is often used as a generic term for the composite material containing hard particles composed of tungsten carbide, along with softer, metallic binder used to hold or cement the particles in place. The creation of this material starts with Tungsten ore that is refined into Tungsten powder (W).
Jun 11, 2015 Tungsten carbide is often used as a generic term for the composite material containing hard particles composed of tungsten carbide, along with softer, metallic binder material used to hold the particles in place. It is a very hard and dense material, generally used to form and shape other materials in processes like forging and machining.
Differences between Tungsten Carbide Hardness Durability. It may seem at first glance that both hardness and durability are directly related, but that is not always the case. For example, gold is softer than many metals used for wedding bands. But it is highly durable as with a little care it will last a lifetime.
