Tungsten carbide plates are made from a composite material consisting of tungsten carbide particles (85-95%) combined with a cobalt or nickel matrix (5-15%). This material gives tungsten carbide plates unparalleled properties:
● Hardness approaching that of diamond (1,500-2,200 HV, 89-93 HRA)
● Compressive strength as high as 6,000 MPa (four times stronger than tool steel)
● Exceptional wear resistance, with an ASTM G65 wear rate as low as 0.02 mm³/h
Key properties driving industrial adoption:
| Property | Tungsten Carbide | Tool Steel | Impact |
|---|---|---|---|
| Hardness (HRA) | 89–93 | 60–70 | 8–10× longer lifespan |
| Heat Resistance | Up to 540°C | 400°C | Stable in high-friction zones |
| Corrosion Resistance | Resists acids/H₂S | Low | Ideal for chemical/oil environments |
Langsun Carbide's production process is ISO certified, combining advanced metallurgical technology with engineering design and manufacturing tailored to specific applications:
Powder Preparation: This process begins with the preparation of tungsten carbide powder, which is then mixed with a binder (usually cobalt). The mixture is then ground to achieve a uniform consistency.
Pressing: A high-pressure press is used to compress the powder mixture into flat rectangular shapes. This step compacts the powder into a solid form, creating a “green” plate ready for sintering.
Sintering: The green plates are placed in a sintering furnace and heated to a temperature near the binder's melting point. This process fuses the tungsten carbide particles together, forming a dense, robust plate with enhanced mechanical properties.
Finishing: The sintered plate undergoes finishing processes such as grinding and polishing to achieve the required dimensions and surface finish. This step ensures the plate meets the precise specifications required for its intended application.
Tungsten carbide plates are utilized across various industries due to their exceptional properties. Here are some of the key applications:
In the metalworking industry, tungsten carbide plates are used as cutting tools, wear-resistant liners, and dies. Their ability to withstand high temperatures and maintain sharp edges makes them ideal for machining operations, enhancing productivity and precision.
Tungsten carbide plates are employed in mining and construction equipment, where they serve as protective liners and wear-resistant surfaces. Their durability ensures that machinery can operate efficiently, even in abrasive environments, reducing downtime and maintenance costs.
In the aerospace and defense sectors, tungsten carbide plates are used in components that require high strength and resistance to wear. Their ability to endure extreme conditions makes them suitable for applications such as armor plating and structural reinforcements.
