Tungsten Carbide Wear Resistance Parts

Tungsten carbide wear parts have become indispensable in various industries due to their impressive durability and exceptional performance. As demands for efficiency and longevity grow, tungsten carbide components are increasingly being adopted in diverse applications like drilling, mining, and manufacturing. Tungsten carbide (WC-Co) has redefined industrial durability with its unique combination of hardness (HV2200+), fracture toughness (TRS ≥3,800 MPa), and corrosion resistance. At Langsun Carbide, we engineer wear-resistant components that withstand conditions where conventional metals fail:


  • Thermal Stability: Maintains structural integrity at 600°C, outperforming steel’s 50% hardness loss at 300°C

  • Wear resistance: In wear tests, the wear rate is 8-10 times lower than hardened steel

  • Custom Microstructures: Grain sizes from 0.5–5μm, optimized for impact resistance or surface finish

Understanding Tungsten Carbide

Tungsten carbide is a compound comprising tungsten and carbon atoms. When these elements combine, they form a super-hard material with a hardness close to diamond. This unmatched hardness makes tungsten carbide an ideal choice for parts that must endure extreme wear and tear. Tungsten carbide is made by heating tungsten and carbon powders to temperatures exceeding 2600 degrees Celsius (4712 degrees Fahrenheit), resulting in a synthesized product that can be pressed and formed into various shapes. Additionally, tungsten carbide offers excellent thermal and chemical stability, ensuring reliable performance under challenging conditions.

Properties of Tungsten Carbide

  • Hardness: Tungsten carbide exhibits remarkable hardness, making it resistant to scratches and wear.

  • Wear Resistance: Its wear resistance surpasses that of steel, which means it retains its form and functionality over time.

  • High Temperature Tolerance: Tungsten carbide can withstand high temperatures without losing its properties, ideal for applications with significant heat exposure.

  • Corrosion Resistance: It is less prone to corrosion, making it suitable for applications involving corrosive environments.


Applications of Tungsten Carbide Wear Parts

  • Cutting Tools: Tungsten carbide is extensively employed in manufacturing cutting tools for machining and drilling thanks to its hardness and durability.

  • Industrial Machinery: Components such as gears, bearings, bushings, and valve seats are often made of tungsten carbide to increase their lifespan and reduce maintenance costs.

  • Mining Equipment: The material is used in mining tools and machinery parts that need to sustain harsh operational conditions.

  • General Engineering: It is applied in various engineering industries to make wear-parts like plungers, pins, and rollers.

Typical Applications of Tungsten Carbide Wear Parts

Tungsten Carbide Nozzles

Tungsten carbide nozzles are widely used in industries that require extreme precision and durability. These nozzles are particularly suitable for high-pressure water jet cutting and spraying, sandblasting and other applications. The main advantages of tungsten carbide nozzles are as follows:

  • Abrasion resistance: Tungsten carbide nozzles can withstand the erosion of high-speed water jets and abrasive particles, ensuring long service life and stable performance.

  • Precision: They can provide precise results, which is crucial for delicate cutting tasks.

  • Corrosion resistance: The chemical stability of tungsten carbide ensures that the nozzles remain reliable even in corrosive environments.

Tungsten Carbide Seal Rings

In industries such as oil and gas, mechanical seals, etc., maintaining airtightness is essential to prevent leaks and ensure system integrity. Tungsten carbide seal rings provide an effective solution to meet these requirements with their superior durability and performance:

  • High hardness: The hardness of tungsten carbide ensures that the seal rings can withstand high pressures without deformation.

  • Wear resistance: They are able to resist wear and tear, usually caused by friction and contact with other machine parts, thereby extending the service life of the equipment.

  • Temperature stability: Tungsten carbide seal rings remain functional at high temperatures and maintain their sealing performance under extreme conditions.

Tungsten Carbide Bushings

Bushings made from tungsten carbide are significant in machines where components rotate or oscillate. These bushings offer key advantages in terms of wear resistance:

  • Enhanced Durability: Tungsten carbide bushings retain their structural integrity over long periods, reducing maintenance needs.

  • Reduced Friction: They minimize friction between moving parts, leading to smoother operation and less energy loss.

  • Corrosion Resistance: These bushings perform reliably in harsh environments, resisting chemical degradation.

MWD&LWD Parts

Measurement While Drilling (MWD) and Logging While Drilling (LWD) are advanced technologies used in the oil and gas industry to obtain real-time data from within the wellbore. Tungsten carbide components are critical in these applications due to their robustness and reliability:

  • High Wear Resistance: Tungsten carbide parts endure the abrasive and harsh conditions prevalent during drilling operations.

  • Thermal Stability: These parts maintain their properties at high temperatures, ensuring consistent data collection and equipment performance.

  • Long Service Life: The durability of tungsten carbide components ensures that MWD and LWD instruments function optimally over long periods, reducing the frequency of part replacements.

Choosing the Right Tungsten Carbide Part for Your Needs

When selecting tungsten carbide wear parts, consideration should be given to the specific requirements of the application. Factors such as grain size, cobalt content, and the working environment should influence the choice. Finer grain sizes provide higher hardness and wear resistance but may require more advanced processing technology and are less impact resistant.



Tungsten carbide wear resistance parts offer unparalleled durability and performance in various demanding industrial applications. Understanding their properties, applications, and benefits can help in making informed decisions regarding their use, ultimately leading to enhanced productivity and cost-efficiency. Invest in tungsten carbide wear parts to ensure longevity and reliable performance in your industrial operations.
