Tungsten carbide (WC) is a composite material made by combining tungsten atoms with carbon atoms in a process called sintering. Tungsten itself is an incredibly dense element—about 1.7 times denser than lead. When processed into tungsten carbide, the resulting material is extremely heavy for its size.

This high density is not just a trivial fact; it's a critical performance feature. The significant weight and mass of a tungsten carbide ring contribute to its exceptional stability and vibration damping. In high-speed rotational applications, lighter materials can be susceptible to micro-vibrations and "chatter," which lead to premature wear and seal failure. A heavy tungsten carbide ring resists these vibrations, maintaining perfect alignment with its mating ring for a consistent, leak-free seal.
