Tungsten carbide is an alloy which has the main components of tungsten carbide powder with metal bender. It is widely used for manufacturing high-speed carbide cutting tools for hard, tough materials. The high-performance tungsten carbide has excellent characteristics.
1. High hardness and excellent wear resistance
The hardness of cemented carbide can reach 86 to 93HRA, which is equivalent to 69 to 81HRC. High hardness can be maintained at 900-1000 ℃ with excellent wear resistance. Compared to high-speed steel, the cutting speed can be 4-7 times higher with 5-8 times service life, which can cut hard material with a hardness of 50 HRC.
2.High strength and high elastic modulus
The tungsten carbide has a compressive strength of up to 6000 MPa and an elastic modulus (4 ~ 7) × 105 MPa, which both are higher than high-speed steel. However, its bending strength is low, typically 1000 ~ 3000MPa.

It is generally resistant to atmospheric, acid, alkali and is not easy to oxidize. There is a wide range of applications in the industries of fluid and chemical, such as various valves used for fluid control including regulating valves, black water valves, lock slag valves, and decompression noise reduction valves, etc.
4.Small linear expansion coefficient
When the tungsten carbide products are working, the shape size the stable
5.The finished products are no longer processed with re-grinding
Due to the high hardness and brittleness, the powder metallurgical formation is no longer cutting or re-grinding, and when the demand is re-processing, it can adopt electric sparks, line cutting, electrolytic grinding and other electric processing or special grinding wheel cutting. It is usually used by a certain specification paper made of cemented carbide, adopting brazing, bonding or mechanical clamping for the blade body or mold.
How To Improve The Performance Of Tungsten Carbide
In order to adapt to the harsh environment under different working conditions, tungsten carbide often needs to be reprocessed to make corresponding changes for the original performance, so what are the methods to change the performance of tungsten carbide?
1. Improve the quality of raw materials
Improve the purity of raw materials
High-strength, high-impact toughness alloys have high requirements for the purity of raw materials, while continuous cutting tool with low impact load but high machining accuracy, have low requirements for raw material purity.
Control the particle size and distribution of raw materials
It should avoid excessively large particles in the carbide or cobalt powder raw materials, and prevent the tungsten carbide from forming coarse carbide grains and cobalt pools during sintering.
At the same time, the size and composition of the particle materials should be controlled to meet the needs of different products. For example, carbide cutting tools should adopt tungsten carbide powder with a fisher particle size of less than 2 microns, wear-resistant tools should use tungsten carbide powder with a particle size of 2-3 microns, and mining tools should adopt tungsten carbide powder with the particle size of larger than 3 microns.
2. Improve the structure of the tungsten carbide
3. Improve or select new hard phase and binder phase
The performance of tungsten carbide is affected by the composition and structure of the hard phase and the binder phase. Generally speaking, when the content of the hard phase is high and the grains are finer, the hardness is high and the wear resistance is good, with poor impact resistance. Improving the hard phase and the binder phase is one method to change the performance.
4. Surface hardening treatment
To solve the contradiction between wear resistance and toughness, hardness & strength of tungsten carbide, surface hardening treatment can be adopted.
The coating is physically or chemically depositing a layer of TiC or TiN on the surface of the cemented carbide to increase the wear resistance. The most rapid development at present is the coated tungsten carbide.
5. Add elements or compounds
6. Heat treatment

Among the many nozzles, the carbide nozzle is the most rugged and the most cost-effective. Its anti-curvature can reach 2300N/mm and hardness can reach HRA90, be suitable for many industries and fields which have high requirements for hardness performance.
The cemented carbide nozzle is sintered by the heat pressure of the heat holes and huckles. It is conducive to the implementation of small work, such as cleaning parts, welding, cleaning handrail, stairs, gauge, or stone carving. It forms a sufficient airflow mode, which increases the abrasive rate by 100% for a given pressure and it is the best choice for high airflow to improve productivity.

For example, the carbide nozzle is widely used in sandblasting to ensure that the products are used for a long time for the best air and abrasives.
The Common Types Of Tungsten Carbide Nozzle
The shape of the hole in the cemented carbide nozzle determines its airflow mode. According to the application industries, there are three types of carbide nozzles that are commonly used, which include tungsten carbide water coal slurry nozzles, carbide atomization nozzles, and carbide oil nozzles.
Tungsten carbide water coal slurry nozzles
The carbide nozzle has a wide range of applications in the hydrocryrid burner, which makes the water coal paste fuel burn much more fully and efficiently by good fuel atomization. Depending on the nature of the fuel, the carbide nozzle can also be divided into pneumatic, mechanical, rotary cup and ultrasonic wave. The rationality of its structure determines the atomization effect of the water coal slurry. The wear resistance and hot-impact resistance of the material determine the service life of the nozzle and directly affect the economics and safety of water coal slurry applications.
The wear of carbide water coal slurry nozzles mainly includes crystal grains, brittle fracture and grinding damage. The higher the CO content in the cemented carbide, the greater the erosion wear is, so it should be selected, which has less CO content. The water coal slurry nozzle made by tungsten carbide, compared to other metal materials, has better wear resistance and longer service life. However, the tungsten carbide itself has a large brittleness and high hardness and the toughness and the thermal impact properties are lower than other metal materials. It is not easy to process. The carbide tungsten can greatly improve the wear resistance of a nozzle.
Tungsten carbide atomization nozzle
The aerosolic form of the carbide atomization nozzle can be divided into types of pressure, rotary, electrostatic, ultrasonic and bubble. Because of its good atomization performance and wide coverage, the carbide nozzle is suitable for spraying, dust removal, and humidification, etc in industrial manufacturing and agricultural production spray.
Compared to other types of nozzles, the tungsten carbide nozzle can achieve a spray effect without an air compressor and the shape of the atomization is generally circular or fanned. In addition, the carbide atomization nozzle is also a very important role in the air conditioner. It is configured on the line of air-conditioning, which effectively reduces the heat generation during the air condition work by atomized water mist.
Tungsten carbide oil nozzle
With the development of the petroleum industry and the increasing energy demand, the carbide oil nozzles can be used with carbide tips to achieve improved drilling efficiency, and extend the service life of the drill bits.
Wide Applications Of Tungsten Carbide Nozzle
The applications of carbide nozzle are very wide, commonly used in automotive, electroplating, surface treatment, high-pressure cleaning, dust removal, cooling, desulfurization, humidification, stirring, etc.
Tungsten carbide nozzles are suitable for sandblasting, painting, electronics, chemical processes, etc. At the same time, it is also the active element for the coal chemical industry slurry output.
Cemented carbide nozzles are also used in different applications, such as wire drawing, line guides and many more other aspects.
