High substitute material! Prevents chipping and breaking with high cobalt carbide material.
In high-speed applications, durability is insufficient, but conventional carbide is too brittle—GF24 responds to such "troubles" in the field.
Have you ever struggled with the brittleness of hard alloys? Powdered high-speed steel cannot withstand wear, but conventional carbide tools suffer from chipping. To respond to such voices from the field, Mizuho Industry developed "GF24." GF24 is a special grade that combines ultra-fine tungsten carbide particles of less than 0.6μm with a high binder design of 24%. This results in: - High hardness of HRA88.0 - High fracture toughness of 15.0 MPa·m¹ᐟ² - Compressive strength of 4.2 GPa - Toughness with a bending strength of 3800 MPa.

Company information
Mizuho Kogyo Co., Ltd. has been a rare manufacturer of carbide tools and various molds since its establishment in 1944, continuing the production and sales of carbide tools for over 80 years. We also offer special surface treatments such as welding rods "Triamant" and "SurmoX treatment." The "SurmoX treatment" does not cause dimensional changes before and after processing due to its coating-free nature, and it can be applied to brazed items and interference fits due to its low-temperature process. Additionally, it can be applied to deep internal diameters where conventional coatings were not possible. This is expected to prevent seizure and adhesion, as well as improve the release properties of powder molding molds. In recent years, we have also been able to manufacture inserts for development projects and small-lot special-shaped inserts in a short delivery time using a method called "plate chocolate manufacturing." Furthermore, please trust Mizuho Kogyo for OEMs of carbide holders with brazing or direct taps, as well as for spot products.
