Why Tungsten Carbide Grit Is Good for Hardfacing Applications?

Tungsten Carbide Grit is well-known for use in hardfacing applications such as on rotary rock bits and tool joint connections that are used primarily in well drilling where tools must withstand severe abrasion and the stresses of high impacts.

How Tungsten Carbide Grits Are Made?

Manufacturers in the prior art, grits have been made by crushing and screening tungsten carbide compositions. This method produced sharp faceted, irregularly shaped particles with inferior wear resistance. It was recognized in U.S. that the irregularly shaped grit obtained by crushing tungsten carbide compositions were subject to wear problems because of the points and pressures on the rits and the lack of uniformity in the grit particles. This patent teaches a method for preparing tungsten carbide powders whereby spheres, cylinders, ovoids or cubes of tungsten carbide can be obtained for use of a tumbling procedure is mentioned for the production of tungsten carbide grit but no mention is made as to how this procedure is to be carried out.

It has been discovered on the later half that if tungsten carbide powder is combined with a suitable organic binder and agglomerated into particles which are sintered to remove the binder and form tungsten carbide grit, grit with blunt and round particles. These blunt tungsten carbide grits are obtained in good yield with a minimum of unusable fine material. The blunt tungsten carbide grit has superior wear resistance properties as compared to the tungsten carbide grit obtained by crusing tungsten carbide blocks or compacts.

Tungsten Carbide Grit and Hardfacing

The process involved in applying tungsten carbide grit to the surface of hardfacing parts. With hardfacing, the base metal is made tougher and harder through the application of a material (in this case tungsten carbide grit) to its surface. Tungsten carbide grit in fact offers a greater level of protection to surfaces than many or most other traditional hardfacing materials.

Various industry applications require various levels of wear resistance. At WEISON, we offer tungsten carbide grit in various mesh sizes that suit particular applications. By using the right mesh size, you can achieve the desired level of protection regarding both impact and abrasion resistance. Tungsten carbide grit can also be applied to use parts in order to restore their deteriorated and worn-down surfaces.

Everything You Want to Know about Tungsten Carbide Grit – Here It Is

Tungsten carbide grit is the material applied to components of applications with a high level of abrasion. It’s applied as an overlay through the process called ‘hardfacing’. Through the method of hardfacing in metal working, tougher and harder material is applied to a base metal. Tungsten carbide grit is used above most traditional hardfacing materials because it is harder and is proven to be a more effective protection against wear from abrasion.

Uses of Tungsten Carbide Grit in Work Environments

Tungsten carbide grit can be created to suit individual applications and work environments. One can alter the grit mesh size as well as the wire matrix to achieve the desired balance of protection from abrasion and impact. Through hardfacing, tungsten carbide grit can be applied to a new part in order to enhance its wear resistance further or to a used part for restoring its worn-down surface.

Why Tungsten Carbide Grit?

Tungsten carbide grit is ideal to use for long lasting wear protection in areas of high abrasive wear. It’s used to keep costly parts – bulldozer blades, wood grinding tips, trencher teeth, and bucket teeth – from wearing down quickly. Using tungsten carbide grit on machinery parts that see a lot of wear and tear significantly extends the life of those parts. For this particular reason, tungsten carbide grit is used in many different applications including woodwaste, agriculture, wear parts, plow attachments, and drilling. Tungsten carbide grit also adds an extra layer of protection to costly parts, increasing efficiency and decreasing downtime.

Widespread Applications of Tungsten Carbide Grit

Tungsten Price

The price of tungsten carbide raw material keeps rising over the whole 2017. According to the statistics of our China hard alloy business network, the main raw material of tungsten carbide powder has been increased from RMB180/kg to RMB270/kg at the beginning of 2017, and the price has soared by more than 50%Tungsten powder is also all the way up from RMB181/kg at the beginning of 2017, the highest in early September when rose to nearly RMB300/kg, even though slightly down afterwards, but there are still RMB274/kg, by the end of year rose more than 50%. The price of the recycled tungsten carbide powder has risen from about RMB158/kg at the beginning of 2017 to 208 yuan/kg at the end of 2017, up by nearly 35 percent.

As for the price of raw material for hard alloy, it can be described as extremely soar. Because of the push of the metal cobalt by overseas prices and domestic downstream especially new energy vehicles ternary battery demand, cobalt price jumped all the way, so as to drive the cobalt powder price also synchronous strong gains, cobalt powder prices have beenraising from early 2017s 300 yuan/kgup to 650 yuan/kg, yearly increasing percentage more than 110%, it's dumbfounded.

The prices of raw material go up, led to the production costs have risen sharply for those who producing tungsten products, but at the downstream, tungsten finished products have not up too much at price through the year, the production enterprises generally face income drops, even an embarrassing situation of without profit. Tungsten product manufacturers have been unable to bear the cost of rising raw materials, and allbe forced to raise their prices start from the tail of 2017.

At the beginning of 2018, the raw material is constantly go up at price, tungsten powder now is about RMB282/kg. tungsten carbide powder, recycled tungsten powder is raising for no exception. all the downstream of tungsten industry be forced to adjust their price.at the beginning of 2018. Chinese traditional new year is upcoming. lots of heavy orders need to be finished before Chinese spring festival, the consuming of tungsten powder becoming strong, however, tungsten powder is regulated by green environment restriction orientation, more and more small and medium W powder producers are coerced into shut down, to some extent cause to shortage so that stimulate the raising of tungsten price.

The Prolific Use of Tungsten in the Medical Industry

That’s obvious, isn’t it!

The remarkable journey of Tungsten from incandescent lamps to different devices and machines hasn’t received the hype like other metals do. The mismatch has been evident since steel, copper, gold, and other metals became the memorable topics of discussion.

Tungsten became the top choice of usage in the medical industry due to several reasons. Tungsten properties, such as high melting point, high malleability, and corrosion resistance edge over the advantages of other metals. These exceptional properties leverage the choice of Tungsten collimators than any other material made collimators.

In Computed Tomography (CT) machines, the key manufacturing component is Tungsten. While this metal is used for making detector arrays of scanners, the circular radiation components are made using Tungsten collimators. Certainly, the advantages of using Tungsten are aplenty, but we cite only a few:

  • Tungsten collimators help in reducing the extra radiations, which is why it’s one of the safest devices for use on a job site.
  • Since the scattered radiation is reduced due to Tungsten collimators, the quality of radiography shots automatically improves.
  • Lauded as an effective radiation shielding material, Tungsten is easy to handle and operate with.
  • Given its non-sparking nature, it also becomes an ideal choice for industrial usage.

Why Is Tungsten An Effective Shielding Material?

Descriptions offered on certain platforms suggest/mention Tungsten as an “effective shielding material” without much explanation. Those dealing with metallurgical explorations have a rudimentary knowledge about the material, but not a lot of them have ample time for explaining the “effectiveness” of Tungsten in simpler terms. Nevertheless, we are here to offer a lucid account about the same.

The chemical element Tungsten with an atomic number of 74 is a lesser discussed material. It has an atomic mass of 183 grams per mole and has a high melting point (as close as 3400 Degrees Celsius). Before CFLs and LEDs made an entry into our daily lives, the regular households had the incandescent light bulbs for illumination. These bulbs had the Tungsten filament in it.

Given its high tensile strength and highly malleable properties, it became a top choice for real-world applications, whether it is in the aerospace industry or in the medical industry. It can withstand high temperatures, making it a major preference for X-Ray production requirements. Tungsten’s efficacy in terms of resisting high temperatures without pitting or bubbling justifies its role as an effective shielding material. Moreover, it’s an effective heat dissipating metal; one of the best alternatives available in the marketplaces.
