1. Hardness and durability. While black zirconium and tungsten carbide rings are durable and hard, tungsten carbide's hardness tends to hang on the brittle side, meaning that it can easily crack if it drops on a hard surface, and it may not last forever as you may have hoped. Black zirconium easily lasts for a lifetime with proper care.

Tungsten carbide (WC) is a widely used engineering material which is usually prepared at high temperature. A new mechanism for synthesizing nanoscaled WC at ultralow temperature has been discovered.
When it comes to cost, cobalt rings are generally less expensive than tungsten. The average cost of a cobalt ring is around $125 while tungsten can range up to $400 or more depending on the style and design. If you're looking for an affordable option with a contemporary look, then cobalt could be the right choice for you.

Melting point of Tungsten Carbide is 2867 °C. Note that, these points are associated with the standard atmospheric pressure. In general, melting is a phase change of a substance from the solid to the liquid phase. The melting point of a substance is the temperature at which this phase change occurs. The melting point also defines a condition ...

Aug 2 2009. Tungsten Carbide is often referred to as a Hard Metal due to it's very high hardness in relation to other metals. Typically a Tungsten Carbide Hard Metal can have a hardness value of 1600 HV, whereas mild steel would be in the region of 160 HV a factor of 10 lower. Although called a hard metal, Tungsten Carbide is actually a ...
Cemented carbide can be used in a wide variety of applications as it is extremely versatile. Steel: high toughness, but low hardness.

Tungsten carbide is a fine dark powder which can be squeezed and framed into shapes for use in manufacturing industries, cutting devices, abrasives, defensive layer penetrating rounds, other equipments and tools [6]. Tungsten carbide is double the density of steel and is nearly two times stiffer than steel [7].
Tungsten carbide is a dense, metallike substance, light gray with a bluish tinge, that decomposes, rather than melts, at 2,600° C (4,700° F). It is prepared by heating powdered tungsten with carbon black in the presence of hydrogen at 1,400°–1,600° C (2,550°–2,900° F). For fabrication, a process developed in the 1920s is employed: the …
Scheele discovered "Tungsten" in 1781; however, it took 150 years more before the efforts of Scheele and his successors led to the use of tungsten carbide in the industry. We use cookies to enhance your experience.
Carbide Composition. A key consideration when brazing carbides is wettability of the filler metal on the carbide, as you need sufficient wetting to produce a strong joint. Silver-based (BAg) brazing filler metals typically exhibit good wetting on tungsten carbides. However, cobalt content leads to a concern for wettability of carbide.
Cemented carbide, (also referred to as hard metal), is a material created by "cementing" very hard tungsten monocarbide (WC) grains in a binder matrix of tough cobalt metal, using the liquid phase sintering process. The combination of WC and metallic cobalt as a binder is a well-modified system not only relating to its properties, but also ...
