What is tungsten carbide?

Commodity prices are on track for their biggest rally in more than a century, while fixed-income assets have seen their longest run of outflows as the war in Ukraine adds to inflationary pressures in the global economy emerging from the coronavirus lockdown, according to Bank of America.

"Commodity prices this year are on track to record their biggest gains since 1915." the bank said in its weekly briefing. They cite many factors, such as pandemics, lockdown, civil strife, wars, excessive monetary and fiscal stimulus, and supply chain disruptions, that have led to "historically" high inflation.  

By the same token, it said government bonds were heading for their worst year since 1949, and "negative-yielding bonds will quietly disappear" from the market as central banks embark on a monetary tightening cycle and raise interest rates to tame soaring inflation.  

The prices of many commodities like the WC powder are expected to increase in the future.

Introduction to Tungsten Carbide
Tungsten carbide (chemical formula WC) is a compound (especially a carbide) containing equal amounts of tungsten and carbon atoms. 
In its most basic form, tungsten carbide is a fine grey powder, but it can be pressed into shape by sintering and used in industrial machinery, cutting tools, chisels, abrasives, armor-piercing bullets, and jewelry.
Tungsten carbide is about twice as hard as steel, with Young's modulus of about 530-700GPa, twice the density of steel - almost halfway between lead and gold. 
 
High strength, high density, and high hardness are the distinguishing characteristics of tungsten carbide, making it a versatile material with a variety of uses. Tungsten carbide can withstand extremely high temperatures, making it an excellent material for machining and cutting tools, even furnaces, and can conduct electricity. Abrasion and corrosion resistance are among the other properties of tungsten carbide.
Tungsten carbide has a high melting point of 2,870 °C (3,140 K). It has a boiling point of 6,000 °C (6,270 K), thermal conductivity of 110W·m (-1) ·K (-1), and thermal expansion coefficient of 5.5μm·m (-1) ·K (-1) at a pressure equivalent to 1 atmosphere (101.325 kpa). 
Tungsten carbide is very hard, with a Morse rating of about 9 to 9.5 and a Vickers number of about 2600. It has a young's modulus of about 530-700 gpa, a volume modulus of 630-655gpa, and a shear modulus of 274GPa. Its ultimate tensile strength is 344 MPa, its ultimate compressive strength is about 2.7GPa, and Poisson's ratio is 0.31. 
The p-wave velocity (sound speed) through the tungsten carbide thin rod is 6220 m/s. 
Tungsten carbide has a low resistivity of about 0.2 µ ω ·m, comparable to some metals, such as vanadium. 
 
Tungsten Carbide VS Diamond
Tungsten carbide is a very hard material. It is predicted to have a Mohs hardness of 8.5 to 9, second only to diamonds. This makes it a valuable metal with many different uses.  Tungsten carbide bits are very tough for operations where other metal bits can become blunt and break.
 
Tungsten Carbide VS Steel
Steel has three times less rigidity than tungsten. This rigidity makes tungsten stronger than steel and titanium. Tungsten is very durable and can withstand many penalties in any job.  Whether it's tungsten powder or tungsten carbide blades, this compound gets the job done. 
 
Tungsten Carbide Application
Buildings
Buildings need to use tools of high strength and toughness so that they can withstand the materials used to form most structures. Materials such as cement and asphalt are difficult to penetrate and require exceptionally durable and strong blades or drills, such as those made of tungsten carbide. Tungsten carbide is commonly used in building materials such as saws and drill bits because it is almost unbreakable.
 
Industrial alloys 
To make electronics, construction projects, industrial gears, and even aviation equipment, alloys are made by mixing metals with other metals or elements. These alloys have specific properties, such as strength or heat resistance, which are necessary for each product and its use. Alloys made from tungsten carbide are a particularly popular choice for building materials and tools. About 17% of tungsten carbide is used to make these alloys. 
 
Production of surgical tools 
Tungsten carbide is commonly used to make surgical instruments because it improves their performance and is resistant to corrosion. It increases the life and strength of surgical tools. The properties of tungsten carbide, such as its ability to sharpen while maintaining hardness, are well suited to the surgical industry.
 
Others
Because of its durability and strength, tungsten carbide can be used in sports equipment such as golf clubs. It can be used for Musical Instruments such as guitar slides. Another important use of tungsten carbide is for the nibs of ballpoint pens. Tungsten carbide is also used in electrical components, especially light bulbs, because of its heat resistance.  Another application of tungsten carbide is in armor-piercing ammunition because it is a durable and tough material. In addition, another interesting and avant-garde application of tungsten carbide is in space satellites, because it can resist extreme temperature fluctuations.

For Germany, the largest economy in Europe, the impact of the Russian-Ukrainian conflict on the natural gas market is the most obvious. This also exposed the serious dependence of some German industrial enterprises on Russian natural gas. Some analysts pointed out that the instability of natural gas supply has had a big impact on the German economy and threatened its market competitiveness because alternative energy supplies will not be cheap and difficult to come quickly. Increased uncertainty over natural gas supplies is putting enormous pressure on German manufacturers in sectors ranging from steelmaking to chemical WC powder for the time being, but the market demand for WC powder in the future will also change with the influence of various external factors. If you need WC powder, please feel free to contact us.
