Cemented Carbide Disc for Cutting and Wear Applications | Tungsten Carbide Industrial Discs Supplier
-
Cemented carbide discs are high-performance industrial components made from tungsten carbide and cobalt binder.
They offer extreme hardness, wear resistance, and high stability under heavy load and high temperature conditions.
They are widely used in cutting tools, industrial machining, and wear-resistant mechanical applications.
Description
1. What is Cemented Carbide Disc
Cemented carbide, commonly known as tungsten carbide or carbide, is a composite material.
It consists of hard carbide particles (primarily tungsten carbide WC) bonded with a metallic binder such as cobalt (Co).
This combination produces a material with extremely high hardness and wear resistance.
Cemented Carbide Disc is a high-performance industrial component known for its extreme hardness and wear resistance.
It is produced through powder metallurgy, forming a material between metal and ceramic properties.
2. Material Composition
Hard Phase
Primarily tungsten carbide (WC) grains provide high hardness.
Binder Phase
Cobalt (Co) is commonly used as binder material.
Nickel or iron may also be used depending on application requirements.
The binder “cements” hard grains together and improves toughness.
3. Key Properties of Cemented Carbide Disc
| Property | Description |
| Hardness | 1200–2000 HV, much higher than hardened steel |
| Density | Approx. 14.5 g/cm³, very high material density |
| Thermal Stability | Maintains performance up to 800°C |
| Elastic Modulus | 2–3 times stiffer than steel |
4. Manufacturing Process
Powder Metallurgy
Cemented carbide discs are produced using powder metallurgy technology.
Tungsten carbide powder is mixed with cobalt binder and pressed under high pressure.
Sintering Process
The compacted material is sintered at around 1400°C.
This process bonds particles into a dense and strong structure.
5. Applications of Cemented Carbide Disc
Used in industrial cutting tools, wear-resistant components, and mechanical systems.
Suitable for high-speed and high-load working environments.
Widely applied in machining, metal cutting, and industrial processing industries.

FAQs
1. Is "Cemented Carbide" the same as "Tungsten Carbide"?
Essentially yes.
Tungsten carbide (WC) refers to the hard phase.
Cemented carbide refers to the full composite material with binder.
2. Why are these discs more expensive than steel?
Due to high raw material cost of tungsten and cobalt.
And complex sintering manufacturing process at high temperature.
3. Can I sharpen a carbide disc myself?
Only with diamond tools.
Standard grinding wheels cannot machine carbide materials.
4. How do I prevent cracking?
Avoid impact and vibration during operation.
Ensure machine rigidity and avoid thermal shock.
5. Which grade should I choose?
Low cobalt grades offer higher hardness but lower toughness.
High cobalt grades provide better impact resistance.
6. Are carbide discs rust-proof?
Tungsten carbide is corrosion resistant.
However cobalt binder may corrode in humid or chemical environments.
Nickel binder grades provide better corrosion resistance.
