Tungsten carbide products

Tungsten carbide is a material used for a number of industrial applications and it is characterised by its high strength, toughness and hardness. Its name derives from the Swedish for tung (heavy) and sten (stone) and it is mainly used in the form of cemented tungsten carbides. Cemented carbides (also known as hardmetals) are made by 'cementing' grains of tungsten carbide into a binder matrix of cobalt or/and nickel.
Tungsten carbide as a material can vary in carbide grain size (0.2 – 50 microns) and by binder contents (up to 30%), as well as by the addition of other carbides. By varying the grain size of the tungsten carbide and the binder content in the matrix, engineers have access to a class of materials whose properties can be tailored to a variety of engineering applications. This includes high-tech tools, wear parts and tools for the construction, mining and oil and gas sector.
Tungsten carbide products typically have a high resistance to wear and can be used at high temperatures, allowing tungsten carbide's combined hardness and toughness to significantly outperform its steel product equivalents.

Tungsten Carbide Coatings

Here at Chinatungsten Online, the most frequently applied wear resistant coating is tungsten. Using our different HVOF systems allows consistent production by choosing powdered feedstock best for your application. Our spray rooms are designed to handle different components, utilizing large turning capabilities with equipment from robots and X-Y gun manipulators to overhead cranes; and specialty-built fixtures for handling repetitive production and complex masking fixtures to protect uncoated areas.
In the continuous-combustion high-velocity oxyfuel HVOF thermal spray process, a fuel gas and oxygen are combusted in a high-pressure chamber, reaching temperatures of 4500 to 5600°F. The hot, high-pressure gas is ejected through a small-diameter nozzle and accelerated down a long barrel at supersonic speeds. Powder, such as Tungsten Carbide is also injected into the nozzle, where the particles mix with the speeding gases and reach velocities of 2500 ft/s to more than 3000 ft/s.
The high speeds impart tremendous amounts of kinetic energy to the particles. Remember that kinetic energy equals half the mass of the particle times the square of its velocity (KE= 1/2 mv2). When these highly energetic particles strike the substrate, the velocity goes to zero and the kinetic energy is absorbed by the particle, causing it to melt in a millisecond. Subsequent particles arrive almost simultaneously, rapidly building up the coating. The result is a very dense adhesive/cohesive coating. It has comparatively very high bond strength, low residual stress, low porosity (typically less than 0.5%), and high wear resistance.
Here at ASB Industries, the most frequently applied powder is tungsten carbide with a cobalt binder. Tungsten carbide melts at 5200°F, and is extremely hard, with Vickers hardness number 2242. On the other hand, cobalt has a melting point of 2460°F, and Vickers hardness number is 1043. Coating properties such as hardness, wear resistance, and strength depend primarily on the grain size and volume fraction of the tungsten carbide particles. Therefore, WC-Co coatings can be designed to provide the specific properties needed for an application by controlling the grain size of the tungsten carbide particles and their volume relative to cobalt. In general, cobalt content ranges from 5 to 30 wt%, and WC grain sizes range from one to eight microns, although for some applications grain size may reach 30 microns.
ASB Industries’ on-site and in-house capabilities in paper mills allow a long lasting carbide grip surface applied to roll surfaces for different processing stages during paper production. ASB will adapt carbide spraying parameters using our flame spray equipment to work best with the paper quality and thickness.
Erosion, abrasion and corrosion are considerations for choosing different chemistries and binder materials. Tungsten Carbide is typically used for extreme wear conditions in almost every industry.
In steel and metals production, tungsten carbide coatings, along with tungsten weld coatings, are widely used from ore production through finished product. A multitude of accepted applications show dramatic maintenance cost reductions and improved production quality.
In power generation where coal is the fuel source, components are required to be protected from extreme abrasion under demanding production seasonal schedules. ASB Industries has a wide variety of solutions incorporated in many critical components.
If your application requires a specific finish, then ASB Industries in most cases will be able to complete your carbide coated surface to varying surfaces finishes or Ra. From large to small components, ASB Industries will most likely be able to finish your project with our diamond grinding and diamond super finishing equipment.

What is Tungsten Carbide or Hard Metal?

Tungsten Carbide is often referred to as a Hard Metal due to it’s very high hardness in relation to other metals.
Typically a Tungsten Carbide Hard Metal can have a hardness value of 1600 HV, whereas mild steel would be in the region of 160 HV a factor of 10 lower.
Although called a hard metal, Tungsten Carbide is actually a composite material with hard particles of Tungsten Carbide embedded in a softer matrix of metallic Cobalt .
What is the Chemical Formula for Tungsten Carbide?
The chemical formula for Tungsten Carbide is WC.
What is the History of Hard Metals or Tungsten Carbide?
Tungsten Carbide was originally developed in Germany in the 1920’s as there was a requirement for die materials that were able to stand up to the high wear encountered in the drawing of tungsten filaments for light bulbs
How is Hard Metal or Tungsten Carbide Made?
Tungsten Carbide Hard Metals are primarily produced using a Powder Metallurgy process, whereby the powdered forms of tungsten carbide and cobalt are mixed using ball mills, a binder material is added to hold the powders together during the next stage of the process which is compaction or pressing.
During the compaction processes, hydraulic presses or isostatic presses are used to compact the powders into a shape which approximates the design of the finished product.

Coated Cemented-Carbide Grade is suited for steel turning

GC4325 indexable inserts are designed for increased cutting speeds and longer, more predictable tool life with high reliability over extended broad ISO P25 application area. Insert substrate and coating withstand elevated temperatures, reducing effect that causes excessive wear. Capability to maintain insert edge line at high temperatures promotes cutting speeds and security through more predictable and extended tool life.

This latest innovation in tool material provides a new, higher potential for increasing cutting speeds and a longer, more predictable tool life with very high reliability, over an extended broad ISO P25 application area.

Predictability has become increasingly important in today’s machining, especially where there is limited supervision in production. There are always a number of threats to the edge line remaining intact long enough in steel turning. One challenge is the breadth of the ISO P25 application area, which includes several very different materials, from ductile low-carbon steels to high-alloy hard steels, bar material to forgings, castings to pre-machined parts. The advances with the new grade, GC4325, will actually help users resist holding back on cutting-data levels. The grade provides extremely high process security through its ability to retain an intact edge line.

Withstands higher temperatures.

The insert substrate and coating of GC4325 have been developed to better withstand high temperatures, thereby reducing the effect that causes excessive wear.

As a bonus, the grade is highly capable of maintaining the insert edge line at higher temperatures, which translates into the capability for higher cutting speeds with added security through more predictable, longer tool life.

With all this in mind an average productivity increase of 30 percent from today’s existing levels is now available. The grade represents a new generation of performance with coated cemented-carbide indexable inserts, providing a new potential to be tapped throughout a large and diversified application area.
