Understanding Tungsten Carbide

1. What is Tungsten Carbide?

Tungsten carbide is a composite material made up of tungsten and carbon atoms in equal proportions. It is known for its remarkable hardness, ranking just below diamond on the Mohs scale. This extraordinary hardness makes tungsten carbide ideal for applications that require resistance against wear, erosion, and high pressures.

2. Properties of Tungsten Carbide

Tungsten carbide exhibits several desirable properties that make it an excellent choice for mechanical seals. These properties include:

a) High Hardness: Tungsten carbide's exceptional hardness ensures resistance against abrasion, making it highly suitable for sealing applications where surfaces may experience harsh friction.

b) Corrosion Resistance: Tungsten carbide is resistant to most chemicals, acids, and alkalis, making it ideal for demanding environments where corrosion is a concern.

c) Thermal Stability: Tungsten carbide maintains its structural integrity and sealing performance over a wide range of temperatures, from cryogenic conditions to high heat environments.

d) High Strength: With a tensile strength comparable to some steels, tungsten carbide provides mechanical seals with the necessary strength and durability to withstand demanding industrial operations.

Applications of Tungsten Carbide Mechanical Seals
