Wedding bands made of carbide contain other materials known as binders, usually metals such as nickel and cobalt. Cobalt has been known to cause allergic reactions on the skin of the wearer, so many manufacturers are turning toward substitute materials. Despite the common misconception that carbide rings cannot be removed in emergency situations, the jeweler's saws used in emergency rooms and jewelry shops can cut through any material that a ring might be made of.

It is important to note that tungsten carbide is made in nearly two dozen different grades that have different properties, depending on what each will be used for. They are almost all variations of just a few parameters: grain size, hardness, and the degree to which a binder is used. Generally, the higher the percentage of the finished product that is composed of binding materials like nickel, the softer it will be and the more it will wear. The size of the original powder grains makes slightly less difference, but can affect the amount of shock that the product will be able to withstand.

Tungsten carbide can be made by reacting tungsten and carbon at temperatures of around 2,552 to 3,632°F (1,400 to 2,000°C). It is then often made into mills and cutting tools for industrial use, which are able to withstand heavy use and high temperatures. Military organizations also use it in armor-piercing ammunition as an alternative to depleted uranium because of its very high density and hardness level. Some sporting goods are made stronger and more durable by the addition of carbide. Trekking poles used by hikers, for instance, use carbide tips in order to gain traction on hard or rocky surfaces.

Several common consumer goods contain tungsten carbide, including razor blades and the rotating tips of ballpoint pens. It has also become increasingly common for it to be used in men's wedding bands. When used in this way, the bands have a dark hue that can be polished to a mirror-like shine. Due to the toughness of the material, these rings will remain shiny and scratch-free for decades.

Tungsten carbide is an inorganic chemical compound that contains equal numbers of tungsten and carbon atoms. It is sometimes colloquially referred to as simply "carbide." In its most basic form, it is a fine gray powder, but it can be pressed and formed into shapes for use in industrial machinery, tools, abrasives, as well as men's jewelry.

The notable and rare combination of physical properties possessed by tungsten carbide makes it useful for a variety of applications. It is extremely strong and wear-resistant. There are only a few materials on earth that can be used to cut or engrave it, with industrial diamond abrasives being one of these. Its tensile strength is very high, but it is brittle under high pressures as a result. The melting point is also very high, at 5,200°F (2,870°C). To boil, it must be heated much further, to 10,382°F (6,000°C).

Tungsten carbide products are not metal alloy products but products of powder metallurgy.Tungsten carbide and cobalt powder are mixed and fused under high temperature to make tungsten carbide products.

Tungsten carbide products have good hardness. The hardness of tungsten carbide products contributes greatly to its durability when sectioning. The durability of tungsten carbide products depends on various factors, like using frequency, take care of using and others.

It is said that tungsten carbide is the teeth of the modern industry. We believe this and we have made efforts to make the teeth sharpen in the past 22 years.

Tungsten carbide, also known as cemented carbide, is a relatively precious material which is critical to many manufacturing processes. Most metal machining processes use tungsten carbide inserts as tool tips, as cemented carbide has excellent hardness and heat resistance properties ideal for drilling, boring, shaping and forming metal workpieces. Most modern face mills, lathe tools and end mills use these cutting tools.

The only downside of using carbide inserts for such a wide range of machining processes is that the tungsten material used in creating tungsten carbide alloys is both scarce and expensive. With most tungsten reserves in the US and other Western countries exhausted, China supplies over 80% of the tungsten used worldwide. In 2005, the International Tungsten Industry Association estimated that at the current rate of global consumption, all tungsten reserves will be used up within 140 years. Tungsten carbide inserts are typically treated as disposable materials, even though only the cutting edges of the inserts are worn when they're disposed.

Solid Tungsten Carbide is more than a scratch-proof metal. Our Hadron model displays Tungsten’s incredible luster which our videos can only barely capture. This modern watch will hypnotize anyone who even glances.  

The name “Hadron” comes from the sub-atomic particle. Discovering the secrets of the universe by using incredible amounts of energy to break open the hadron is the goal of CERN’s famous “Large Hadron Collider”

SOLARRI tungsten carbide watches are hand polished with diamond dust to a microscopically smooth, astonishing, and everlasting mirror shine. This shine is so astonishing due to the interplay of reflected and refracted light, that only seeing one in person can do it any justice. SOLARRI’s tungsten watches also display the natural 5% tint of Titanium color- characteristic of the carbon when mixed with tungsten. At a 5,200° melting point, SOLARRI tungsten carbide watches necessitate a proprietary method of manufacture. Due to the incredible and laborious processes necessary to properly create such a watch, others can only poorly imitate the look. 

SOLARRI’s new line of genuine tungsten carbide watches are at the absolute forefront of watch design, quality and durability. SOLARRI watches embody ultra modern flare with homage to classic roots. Add in a genuine Swiss movement, and the ideal watch is conjured.

Tungsten cemented carbide is the preferred material for parts that must withstand all forms of wear (including sliding abrasion, erosion, corrosion/wear and metal-to-metal galling) and exhibit a high degree of toughness. It exhibits high compressive strength, resists deflection, and retains its hardness values at high temperatures, a physical property especially useful in metal-cutting applications. It provides long life in applications where other materials would not 0ast or would fail prematurely.

Tungsten carbide has a high melting point at 2,870 °C, a boiling point of 6,000 °C when under a pressure equivalent to 760mm of Hg, a thermal conductivity of 84.02 W·m−1·K−1, and a coefficient of thermal expansion of 5.8 µm·m−1·K−1.
Tungsten carbide is extremely hard, ranking ~9 on Mohs scale, and with a Vickers number of 1700–2400. It has a Young's modulus of approximately 550 GPa, a bulk modulus of 439 GPa, and a shear modulus of 270 GPa. It has a very high yield stress at 6800 MPa, but a comparatively low ultimate tensile strength of just 35 MPa.
The speed of a longitudinal wave through a thin rod of tungsten cemented carbide is 6220 m/s.
With a low electrical resistivity of, tungsten cemented carbide's resistivity is comparable with that of some metals.
WC is readily wetted by both molten nickel and cobalt. Investigation of the phase diagram of the W-C-Co system shows that WC and Co form a pseudo binary eutectic. The phase diagram also shows that there are so-called η-carbides with composition (W,Co)6C that can be formed and the fact that these phases are brittle is the reason why control of the carbon content in WC-Co hard metals is important.
