For billionaires, the new crown epidemic is like a 'gold rush'! The Deutsche Presse-Agentur said on the 17th that in 2022, the wealth held by the world's top ten richest people will jump from $700 billion to $1.5 trillion, an average daily increase of $1.3 billion, an increase that exceeds the past 14 years. These 10 people The wealth held by the world’s poorest 3.1 billion people is six times greater than that of the world’s poorest 3.1 billion people. The 10 richest Germans have increased their assets from the equivalent of about 125 billion euros to about 223 billion euros since the start of the Covid-19 pandemic, An increase of about 78%. This wealth is roughly equivalent to the total wealth of the poorest 40% of the population, or 33 million Germans.
In the future, demand for WC powder will grow as fast as the wealth of the rich during the pandemic.
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 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.
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.
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.

Recently, the first press conference of the Boao Forum For Asia Annual Conference 2022 was held. Two flagship reports were released at the conference: "Asia's Economic Prospects and Integration Process 2022" and "Sustainable Asia and the World 2022-Green Transformation in Action in Asia".
The flagship report points out that the global economy will recover in 2021, and the pace of economic integration in the Asia-Pacific has not stopped even in the face of the impact of COVID-19. The Asia-Pacific region has provided new impetus for the world's economic recovery and institutional building.
The report gives an outlook on the Asian economy, noting that a number of factors will affect Asian economic growth. For example, mutated strains such as Delta and Omicron have become more transmissible, and many economies are experiencing epidemic peaks again. The Ukraine crisis has triggered geopolitical changes in Asia and Europe, leading to higher commodity prices, which may affect the global energy supply and energy transformation.
The report pointed out that the Asian economy will still be in the process of recovery in 2022, but the growth rate may moderate. According to the report, Asia's economic growth in 2022 is likely to be lower than the current IMF forecast, which is projected at 4.8%.
Affected by several factors, the supply of the WC powder is erratic and thus its prices are expected to go higher in the future.
