Until now, our high-hardness powder for 3D printers has had a hardness limit of around 87HRA for the molded body, which posed challenges in applications for parts made from some ultra-hard alloys due to insufficient hardness. The newly developed hard powder has a main phase of WC-TiC-Co, and by achieving a fine microstructure, we have significantly improved the hardness of the molded body to 92HRA. This enables 3D printing of ultra-hard alloy powders that require high hardness, contributing to the resolution of conventional challenges. **Expected Applications** - High-precision press molds (extended lifespan and stabilized precision) - Special cutting tools (high wear resistance and high reliability) - Prototype manufacturing (shortened delivery times) Furthermore, since we possess metal 3D printer equipment, we can provide a comprehensive service that goes beyond mere powder sales, including ultra-hard molding tests, material property evaluations, and prototype support. For customers looking for "ultra-hard alloy 3D printing," "hard powder for metal 3D printers," or "ultra-hard powder materials," we offer a total solution that combines materials, molding, and evaluation. Please feel free to contact us for inquiries about the introduction of next-generation ultra-hard alloy 3D printing or prototype consultations.

In recent years, to reduce the emissions of PFAS, which are difficult to decompose and have the potential for long-term environmental persistence, regulations are being considered in Europe. This has narrowed the options for materials in the solid lubricant industry, and alternatives to PTFE are limited. In response to such challenges, we have developed titanium phosphate in a plate-like form with a controlled aspect ratio. Our synthesis technology allows for control of particle sizes from 0.3 to 5 µm, providing uniform plate-like particles. Plate-like titanium phosphate has the following three characteristics for solid lubricant applications: 1) Excellent sliding properties due to the shape characteristics of the plate-like particles. 2) High whiteness, which prevents black contamination of the surroundings. 3) Composed of materials that do not contain fluorine compounds. Our titanium phosphate tends to excel in anti-seizing properties compared to common solid lubricants such as molybdenum disulfide, PTFE, and boron nitride. If you have any of the following challenges, please feel free to contact us: - Want to improve the anti-seizing properties of lubricants. - Want to achieve lubrication performance with a small amount of additive. - Considering measures against PFAS in materials. *For more details, please download the PDF.

Static electricity occurs in familiar places in our lives and can occasionally cause significant problems in manufacturing sites and precision equipment. One countermeasure is the addition of antistatic fillers. Zinc oxide, by doping aluminum (AZO), can reduce the volume resistivity of the powder to about 200Ω·cm and is widely used as an antistatic filler. It has the following advantages over ATO (antimony-doped tin oxide) antistatic fillers: - Lower Mohs hardness than tin oxide, resulting in lower aggressiveness towards manufacturing equipment - Environmentally friendly as it does not contain Sb (antimony), making it safe for humans and the environment - Lower whiteness (gray), making it easier to maintain dark color designs Our company has successfully developed rod-shaped conductive zinc oxide using our unique particle synthesis technology. The rod-shaped zinc oxide is expected to have the following three effectivenesses: 1. Its high aspect ratio makes it easy to form electrical conduction paths. 2. Its rounded corners, due to the crystal structure, make it easy to fill into resins and other materials. 3. By changing the type of doped elements, it is possible to further reduce the volume resistivity. If you have any requests for samples or questions, please feel free to contact us.

"GC" is a green silicon carbide abrasive material that boasts high SiC purity. The hexagonal α-type crystals possess hardness second only to diamond and are also very stable chemically at room temperature. Therefore, they are not affected by chemicals, self-generate sharp cutting edges through fragmentation, and exhibit excellent polishing power. It is used not only for precision lapping and dicing of quartz and ferrite, as well as for wire saws for cutting Si ingots, but also as a wide range of polishing materials for processing hard metals, cutting tools, soft metals such as cast iron and copper alloys, and resins. Additionally, it is suitable as a material for ultra-fine precision grinding wheels. 【Features】 ■ Has hardness second only to diamond ■ Very stable chemically at room temperature ■ Exhibits semiconductor properties electrically ■ Good thermal conductivity and high-temperature resistance ■ Also used as a material for heat sinks (heat dissipation components) *For more details, please refer to the PDF document or feel free to contact us.
