WEAR AND SHOCK RESISTANT CEMENTED CARBIDE

CEMENTED CARBIDE
  • GTi Sereis (General Wear-Resistant Application)
    Used for general wear-resistant applications. This series not only has a very high hardness, but a high modulus of elasticity, high compressive strength at high temperatures. The series serves a wide application in wearresistant tools and various machine parts.

  • GTi-S Series (Shock-Resistant Application)
    Used for shock-resistant applications in hot and cold conditions. This series has, in addition to the excellent thermal crack-resistance and shock-resistance in hot and cold circumstances.

  • GTi-C Series (Thermal Crack Resistant and Corrosion Resistant Application)
    Shows a superior resistance to thermal crack due to repeated heating and cooling. The series has an excellent resistance to oxidation and corrosion at high temperatures, and is most suitable for hot rolling.
MICRO-GRAIN CEMENTED CARBIDE

The micro-grained series is produced by out own unique technology. Utilizing its excellent wear resistance thanks to its high hardness and high compressive strength, the series is widely used for Rotary Knives, Anvils for producing super-high pressures, and in other special wear resistant applications.
