Overview of Mixed Tungsten Carbide Scrap
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 Mixed Tungsten Carbide Scrap
-
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 Mixed Tungsten Carbide Scrap
The mixed tungsten carbide scrap parameter can be determined by several methods depending on the specific material being studied. Some commonly used parameters include:
* Elemental composition: The percentage of each element in the scrap metal, including tungsten, carbon, oxygen, and iron.
* Rock impact loading: The amount of force applied during rock impact to the scrap metal to determine its resistance to deformation under normal stress.
* Elemental form: The type of melting point of the material (e.g., hard rock, soft rock, glass) and the ability to withstand heat changes.
* Catalyst strength: The rate at which catalysts in the material change their activity or change the chemical composition to increase reaction.
These parameters can help guide the use of mixed tungsten carbide scrap for various applications such as feedstock, tuyeres, bolsters, and casting processes.

Applications of Mixed Tungsten Carbide Scrap
-
Cutting Tools: Used in the manufacture of drills, milling cutters, and other metal-cutting tools due to its hardness and heat resistance.
-
Mining and Construction: For drill bits, saw tips, and wear parts in earthmoving equipment due to its exceptional wear resistance.
-
Jewelry: Provides a durable and scratch-resistant alternative to precious metals in rings and other jewelry items.
-
Ballistic Applications: Used in armor-piercing ammunition and protective plates due to its hardness and density.
-
Dies and Punches: In the forming of other metal parts in stamping and punching operations due to its wear resistance and ability to hold a sharp edge.
-
Oil and Gas Drilling: As components of drill bits and wear parts in drilling equipment due to its toughness and resistance to abrasion.

FAQs of Mixed Tungsten Carbide Scrap
Q: How is Mixed Tungsten Carbide Scrap manufactured?
A: Mixed Tungsten Carbide Scrap 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 Mixed Tungsten Carbide Scrap recyclable?
A: Yes, Mixed Tungsten Carbide Scrap 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 Mixed Tungsten Carbide Scrap compare to steel in terms of hardness and toughness?
A: While Mixed Tungsten Carbide Scrap 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 Mixed Tungsten Carbide Scrap 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 Mixed Tungsten Carbide Scrap 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.
