19 Performance Characteristics Of Tungsten Carbide

This is a process that can spray tungsten carbide onto other metal materials in a coating manner, which can improve the wear resistance and other physical properties of metal materials. Let's now introduce some of the performance characteristics of tungsten carbide.
Different grades of tungsten carbide may vary in strength, rigidity, and other properties, but all tungsten carbide materials belong to the basic properties listed below.
1. Strength - Tungsten carbide has very high strength for hard and rigid materials. The compressive strength is higher than almost all melted or forged metals and alloys.
2. Rigidity - The rigidity of tungsten carbide is 2 to 3 times that of steel and 4 to 6 times that of cast iron and brass. The Young's modulus is as high as 94800000 psi.
3. High resistance to deformation and deflection are valuable properties of tungsten carbide. These include spindles for precision grinding and rollers for strip or metal plates.
4. Impact resistance - For very rigid hard materials, the impact resistance is high. Tungsten carbide belongs to hardened tool steel with low hardness and high compressive strength.
5. Heat resistance and oxidation resistance - Tungsten carbide can reach approximately 1000 ° F in oxidizing environments and 1500 ° F in non oxidizing environments
6. Low temperature resistance - Tungsten carbide maintains toughness and impact strength within the low temperature range. (-453 ° F).
7. Thermal conductivity - The range of tungsten carbide is twice that of tool steel and carbon steel.
8. Conductivity - Tungsten carbide has the same range as tool steel and carbon steel.
9. Specific heat - The content range of tungsten carbide is 50% to 70% of carbon steel.
10. Weight - The specific gravity of tungsten carbide is 1-1/2 to 2 times that of carbon steel.
11. Thermal Hardness - As the temperature rises to 1400 ° F, tungsten carbide retains most of its room temperature hardness. At 1400 ° F, certain grades are equivalent to the hardness of steel at room temperature.
12. Tolerance - Even many surfaces of complete parts can be used in the same way they come from the furnace, "sintering", such as mining or drilling blocks. In parts that require precise grinding accuracy, such as stamping molds, tight tolerance prefabricated parts are provided for grinding or EDM.
13. Tightening method - Tungsten carbide can be fixed to other materials using any of the three methods; Brazing, epoxy resin bonding or mechanical methods. When providing preforms for grinding or EDM, careful consideration must be given to the low thermal expansion rate of tungsten carbide.
14. Friction coefficient - Compared to steel, tungsten carbide composites exhibit lower dry friction coefficient values.
15. Quenching tungsten carbide composite has excellent surface wear resistance and welding performance.
16. Corrosion resistance - The corrosion resistance of special grades is close to that of precious metals. For many applications, conventional grades have sufficient corrosion resistance conditions.
17. Wear resistance - Under conditions such as wear, corrosion, and wear, the wear length of tungsten carbide is 100 times that of steel. The wear resistance of tungsten carbide is better than that of wear-resistant tool steel.
18. Surface Treatment - The surface treatment of the sintered section is approximately 50 microinches. Using diamond grinding wheels for surface, cylindrical, or internal grinding can produce products of 18 microinches or better, and can produce products as low as 4 to 8 microinches. Diamond grinding and honing can produce 2 microinches and polishing is as low as ½ Microinches.
19. Dimensional Stability - Tungsten carbide does not undergo phase transformation during heating and cooling, and maintains its stability indefinitely. No heat treatment required.
