Overview of tungsten carbide bar rod
Tungsten Carbide (WC) is a hard, brittle, and corrosion-resistant material composed of equal parts tungsten and carbon atoms. It is a popular member of the cemented carbide family, known for its incredible hardness, strength, and thermal stability. Tungsten carbide is often used in industrial applications requiring high wear resistance and the ability to maintain sharp edges, even under extreme conditions.
Features of tungsten carbide bar rod
-
Exceptional Hardness: With a Mohs hardness of 9.0 to 9.5, tungsten carbide is one of the hardest materials available, second only to diamond.
-
High Density: Its density ranges from 14.5 to 15.6 g/cm³, providing substantial mass in a small volume, beneficial for applications like balancing and weighting.
-
Thermal Stability: Retains its hardness up to temperatures around 1000°C, making it suitable for high-temperature applications.
-
High Young’s Modulus: Possesses a high modulus of elasticity, indicating stiffness and resistance to deformation under load.
-
Brittleness: Although extremely hard, tungsten carbide is also brittle, requiring careful handling to avoid chipping or fracturing.
-
Chemical Resistance: Resistant to corrosion from most acids except for hydrofluoric acid and strong alkalis, and is not attacked by most organic materials.

Parameters of tungsten carbide bar rod
Tungsten carbide bar rod is a type of structural material used in various applications such as aerospace, automotive, and jewelry industries. It consists of high-quality tungsten carbide particles bonded together through a composite matrix. The properties of the bar rod include its strength, hardness, and wear resistance.
The parameters that affect the performance of tungsten carbide bar rod include:
1. Particle size: The larger the particle size of the carbide, the lower the melting point of the material and the greater its density. However, it also increases the cost of the bar rod.
2. Carbon content: The higher the carbon content of the carbide, the higher its hardness and wear resistance. However, it can also increase the cost of the bar rod.
3. Composition: The composition of the carbide determines its properties such as the amount of impurities present, which can affect the mechanical properties and durability of the bar rod.
4. Manufacturing process: The manufacturing process used to produce the bar rod can affect its quality, cost, and availability. For example, using a more expensive casting method or a higher processing temperature can result in better-quality bars but may be more expensive.
Overall, the choice of tungsten carbide bar rod depends on the specific requirements of the application and the trade-offs between different parameters.

FAQs of tungsten carbide bar rod
Q: How is tungsten carbide bar rod manufactured?
A: tungsten carbide bar rod is typically produced by mixing tungsten carbide powder with a binder metal (commonly cobalt), pressing the mixture into shape, and then sintering it at high temperatures to form a solid, tough material.
Q: Is tungsten carbide bar rod recyclable?
A: Yes, tungsten carbide bar rod is highly recyclable. Scrap and worn-out tungsten carbide tools can be collected, reground, and reused or reprocessed back into tungsten carbide powder.
Q: How does tungsten carbide bar rod compare to steel in terms of hardness and toughness?
A: While tungsten carbide bar rod is much harder than steel, making it suitable for cutting and drilling harder materials, it is less tough, meaning it is more prone to chipping or breaking under impact compared to steel.
Q: Can tungsten carbide bar rod be machined easily?
A: No, due to its extreme hardness, tungsten carbide is very difficult to machine using conventional methods. It often requires specialized grinding or electrical discharge machining (EDM) techniques.
Q: Is tungsten carbide bar rod dangerous to health?
A: In its solid form, tungsten carbide is generally safe to handle. However, during grinding or machining, dust containing tungsten carbide and cobalt binder can be released, which can be hazardous if inhaled. Proper protective measures are necessary.
