Which metallic binder is used can have an effect on the final product. For instance, if a tungsten carbide ring is made with cobalt, then it may cause a rash on the finger of the person wearing it, or it may tarnish by coming into contact with the oils produced by a person's skin. Nickel on the other hand does neither of these things, and it creates a safer, more durable product. Unfortunately though, nickel is much more expensive. So like any product, the particular components required should be taken into account before manufacturing to be sure that the final result has all the necessary attributes.

The process for making tungsten carbide is simple. Equal parts powdered tungsten and carbon are mixed together along with a metallic binder. The most common binders currently in use are cobalt and nickel. The mixture is compacted into a shape, and it's then heated to above the melting point of the binder. The tungsten carbide, which is powdered, is then surrounded by the molten binder. As the slurry dries, the binder holds the tungsten carbide in a matrix that's extremely hard and durable. tungsten carbide that uses a bonding agent is a composite metal, but it's rarely an issue.

Tungsten carbide is an extremely hard and durable metal that's used for everything from industrial applications to men's jewelry. A combination of the extremely hard metal tungsten and carbide mixed together with another metal binding agent, tungsten carbide can a hardness of up to 9.5 on the Moh's scale (not very far below diamond, which is the hardest on the scale). Tungsten carbide is also chemically inert, and will not rust or react with other chemicals. Naturally a steel gray color and coming in a powdered form, tungsten carbide can be molded and shaped through extreme heat and pressure into a variety of shapes and forms.

Insert carbide drills offer a cost-efficient alternative to solid carbide drills, especially for medium- and large-size holes. Insert carbide drills allow you to change the insert when it dulls, which is much less expensive than replacing the drill.

What Is Tungsten Carbide?
Tungsten is a heavy, gray metal with bluish overtones. When mixed with black carbon, tungsten carbide is created.
 
General Process
The compound is made by heating pulverized tungsten with black carbon, when hydrogen is present. Temperatures range from 2,550 to 2,900 degrees F or 1,400 to 1,600 degrees C. A common method for making the compound was developed in the 1920s in Germany and involves mixing powered tungsten carbide with cobalt. This mixture is then made into the required shape and heated to 2,550 to 2,900 degrees F or 1,400 to 1,600 degrees C. This heat melts the tungsten carbide partially, working as a cement. These tungsten carbide-cobalt creations are known by the names Carboloy and hardmetal.
 
Another Process
The tungsten and carbon is made into a powder using a pulverizer. The materials are then placed into a crucible and heated using an arc of electricity. The two materials then combine creating the tungsten carbide.

A gray, inorganic material, tungsten carbide functions as a hardener in armor-piercing projectiles, the sharp edges of drills and saws, and cast iron. Besides industrial uses, it is also used to create jewelry due to its hardness and deduced risk of allergic reactions among those with sensitive skin, among other desirable properties.

Tungsten carbide is a common term used when discussing jewelry. However, tungsten carbide is used in a wide range of manufacturing processes. In many cases, tungsten carbide contains cobalt. Cobalt contains nickel and chromium. According to the New Jersey government website, these chemicals can increases the chances of severe asthma and "hard metal lung" disease. The average employee working with tungsten carbide does not have access to the testing equipment necessary to test for cobalt. However, thanks to government regulations, there is one way you can determine of the tungsten carbide you work with has cobalt in it.

Carbide is a compound that is formed from carbon and another metal, typically tungsten, although there are many types of carbides, all with slightly different properties. Carbide is noted for its strength and durability and is often used in parts for tools. Because it is designed for durability, carbide has some fairly unique characteristics and determining if an item is made from carbide is not very difficult. Learning to distinguish carbide from other materials can be a valuable skill, as recycling carbide is fairly profitable.

Tungsten carbide is known for its hardness and high melting point. On the Mohs scale for testing hardness, tungsten carbide receives a rating of nine, surpassed only by diamonds, which have a hardness of 10. This hardness makes tungsten carbide very scratch-resistant. The melting point of tungsten carbide is around 2,600 degrees Celsius. By itself, tungsten carbide is not a naturally occurring material, it is only produced by combining the elements of tungsten and carbon.
 
Uses
Cutting tools for drilling, mining and construction often incorporate the use of tungsten carbide. These are undoubtedly the biggest markets for tungsten carbide, accounting for around 60 percent of its use. The use of this material in jewelry is becoming popular. Everything from rings to necklaces can be fashioned out of tungsten carbide. Tungsten carbide is also used on the tips of trekking poles and as spikes on snowmobile equipment. It is also used in ball point pens to align the roller ball with ink. Filaments from light bulbs are made out of tungsten because of its resistance to heat.
 
Military
Tungsten carbide is used in the creations of some weapons' ammunition. Armor-piercing ammunition is manufactured from tungsten carbide.
