How to Recognize Carbide

Details: Category: Tungsten Information; Published on Tuesday, 10 September 2013 09:28; Hits: 1852

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

Details: Category: Tungsten Information; Published on Tuesday, 10 September 2013 09:25; Hits: 1762

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.

Major Producers of Tungsten

China, Russia and Korea are all major producers of tungsten, the primary material needed for tungsten carbide. Large reserves of tungsten can be found in certain countries such as Bolivia, Canada and the United States. Today, around 30,000 tons of tungsten carbide are produced annually throughout the world. Only 10 tons per year were being manufactured in the 1930's when it was first gaining widespread use.

Tungsten itself was discovered in the later 18th century, however, widespread use of tungsten carbide did not begin until the early 1920's. More useful applications were discovered in the 1930's when tungsten carbide was used in the milling and cutting of cast iron.

The Uses of Tungsten Carbide Powder

Details: Category: Tungsten Information; Published on Tuesday, 10 September 2013 09:14; Hits: 1779

Tungsten carbide powder is commonly used for hardfacing metals. Hardfacing is the process in which a tougher, harder material is applied to a softer base metal. Tungsten carbide improves the wear-resistant properties of a base metal. It is applied to mining equipment parts (shovel teeth, heel plates, bucket wheel excavator teeth, wear parts, crushing hammers, cutter drums and longwall miners), mineral processing equipment (hammers, chutes, pulverizing and grinding parts), earth-moving and construction equipment (grader blades, cutting edges, augers, trencher teeth, ground engaging tools and tunneling equipment), drilling tools, processing equipment and agriculture equipment (subsoilers, discs and injectors).
