We will meet various needs for tools and materials and solve all your "troubles"!
This product has high strength due to the nanosizing of the binder's crystal grains. When bonded on a steel surface at 100 to 800 μm, it achieves more than double the strength of brazing through diffusion bonding. 【Features】 ■ Nanosizing of crystal grains ■ High strength *For more details, please refer to the catalog or feel free to contact us.
Non-magnetic, high corrosion-resistant carbide alloy
- The carbide itself has no magnetic properties and does not become magnetized due to external influences. - It has very high corrosion resistance and excellent chemical resistance. - It has superior oxidation resistance compared to general WC-Co based cemented carbides.
Mitigating damage during wire electrical discharge machining.
- Mitigation of damage and coexistence of high hardness in wire electrical discharge machining - Suppression of cracking in wire electrical discharge machining
High affinity metalworking superhard alloy (resistant to adhesive wear and seizure)
- Exhibits excellent lifespan in processing materials prone to galling, such as pure iron and pure copper. - Also excels in resistance to electrical discharge machining and corrosion.
Excellent mirror finish! We will provide according to your needs.
Binderless molds (glass lens molding) can achieve high mirror surface accuracy by controlling the WC particle size through a special sintering method. It is possible to achieve a Ra of less than 1nm. By combining thermal expansion coefficients, we can prevent core misalignment during lens molding. We can provide solutions tailored to your needs, from round bars to blank processed products. 【Features】 ○ Excellent mirror surface quality ○ Core misalignment prevention ○ Customized solutions to meet your needs For more details, please contact us or download the catalog.
A consistent production system from the preparation of raw powder to the final processing of mold tools! We offer a rich lineup.
"Super hard alloy" refers to a hard alloy made by sintering tungsten carbide (WC) with cobalt (Co) or nickel (Ni) as a binder. By adjusting the WC particle size and the amount of binder, it is possible to create various super hard alloys with different hardness and toughness. Fuji Dice has a consistent production system from the preparation of raw powder to the final processing of mold tools, ensuring quality assurance and allowing for reliable adoption. Please feel free to contact us when you need assistance. 【Super hard alloy material lineup (partial)】 ■J: Suitable for mirror finish without binder ■F: Ultra-fine particles with high strength ■N: Fine particles with strength second to F ■D: Versatile balanced type ■V: Prevents the occurrence of discharge cracks *For more details, please contact us.
Improved wear resistance against adhesion with materials that have high affinity for super hard alloys due to a unique formulation!
The "RA Series" is a wear-resistant cemented carbide that improves adhesion wear resistance by reviewing the bonding phase and using coarse particle tungsten carbide (WC), which has a strong affinity with cemented carbide materials. It is ideal as a material for molds used in copper alloy processing. 【Features】 ■ Special-purpose cemented carbide with coarse grain and low Co ■ Composition optimized for applications involving adhesion wear and seizure ■ Suppresses diffusion of the work material into the bonding phase For more details, please refer to the catalog or feel free to contact us.
Zero expansion - does not undergo structural transformation up to -269°C! The Young's modulus is 1.5 times that of commercial products!
"IC-DX" is a low thermal expansion alloy based on Fe-Co-Cr. Since it does not contain Ni, which raises the Ms point, it can achieve both zero thermal expansion and low-temperature structural stability, making it suitable for use in low-temperature environments. This material is being evaluated for use as a pad material for bonding 200mm square fused quartz (aspheric mirrors). Thermal expansion at the operating temperature of 77K (liquid nitrogen) and during alignment adjustments from room temperature to 77K is important. 【Features】 ■ Zero expansion, ultra-low temperature stability, high rigidity, corrosion resistance ■ Coefficient of thermal expansion: 0 ppm/℃ ■ Lower limit temperature for low-temperature use: minus 269℃ ■ Young's modulus: 176 GPa ■ Corrosion resistance equivalent to SUS304 *For more details, please refer to the PDF document or feel free to contact us.
Everloy is a carbide manufacturer capable of providing a consistent production process from precision machining to the supply of mold parts made from super hard materials.
The emergence of resin materials with excellent heat resistance and durability is advancing the resinization of metal parts. Some resins contain additives like glass fibers, necessitating measures against early wear of parts and molds, as well as gas generation, which did not occur with traditional molding machines. We propose solutions to reduce the frequency of part replacements by replacing parts with super hard materials. 【Features】 ■ We offer a lineup of super hard materials that excel in "wear resistance," "corrosion resistance," and "heat resistance." ■ We conduct thorough investigations and condition analyses for short-lived parts. ■ We propose super hard materials tailored to applications and workpieces. Currently, we are providing materials that introduce case studies on solving issues related to mold parts. You can view them via "PDF Download."
Alloy tailored to the production needs of rotors and stators.
We offer the carbide grade 'CF-H40S+'. The CF (Corrosion-free) grade is a carbide alloy specially developed for the mold and tool industry, recognized as a genuine corrosion-resistant carbide alloy (CF grade). It is widely used by many customers as blanks for press and punch processing of rotor and stator sheet components for electric motors. This product, which is a representative of our corrosion-resistant carbide materials (CF grade), has proven its true corrosion resistance over many years. Its continued selection by leading companies in the industry is evidence of its quality.
