High density, high hardness, wearable resistance, high thermodynamic stability, long use life.
Zirconia ceramics is characterized with higher density , higher hardness and wear resistance properties etc, especially its flexural strength and fracture toughness are much higher than other non-metallic materials, the service life is 3-5 times longer than alumina ceramics. used in drawing machines, for the manufacturing of cables and enameled wire, general fine, medium and rod break down drawing applications, and special machines for high-grade steel wire.
