Basic Knowledge of Carbide Alloys
Cemented carbide, which has a very high hardness and exhibits excellent performance as a tool material for processing steel and iron, is made by sintering metal powder at high temperatures. This time, I have summarized the basic knowledge about such super alloys. Please take a look.
We deliver reliable products as a trusted material manufacturer!
The benefits that powder metallurgy technology has brought to humanity are such that it is not an exaggeration to say that today's technological days are built upon them. Motonami Alloy Manufacturing Co., as a manufacturer of carbide materials, considers it its mission to provide as many users as possible with the "benefits of carbide" in an appropriate manner. In this sense, "quality" is the most important proposition. We believe that high and stable quality can only be achieved through the accumulation of awareness and practice by everyone involved in the manufacturing process, and we face our daily operations with this belief. [Features] ■ Delivering reliable products consistently as a material manufacturer ■ Zero cost of quality loss For more details, please refer to our catalog or feel free to contact us.
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.
Knowledge reduces risks and increases options—lessons learned from carbide.
"What is Chokou?" - This simple question prompted us to hold a study session on cemented carbide within Bandai. We shared information on material properties such as hardness and ductility, processing risks, the challenges of tool selection, and even examples of how we have addressed these issues in our company. What I felt again during this session is that correctly understanding the properties of materials directly reduces the risk of failure during processing and leads to better decisions regarding optimal manufacturing methods. For example, in a previous order for a cemented carbide product, we assumed that "adhesion is impossible" and manufactured everything in cemented carbide, only to later learn about an alternative called "cemented carbide thermal spraying." If we had known the options from the beginning, it might have led to reduced costs and processing risks - it was an eye-opening experience. Next time, I will provide a detailed introduction to the actual case of "cemented carbide thermal spraying." *Such initiatives are just a small part of what Bandai does every day. Please take a look at the value we can offer to our customers.
We will continue to produce high-quality materials by leveraging the excellent performance of superhard alloys.
Our company, as a manufacturer of cemented carbide, is engaged in the production and sales of cemented carbide and cemented carbide tools, as well as grinding, machining, and ISO consulting. We believe that controlling the carbon content in a stable state during the manufacturing process is crucial for the quality of cemented carbide. Based on this principle, we incorporate innovative processing methods to produce high-quality materials (Nice Kind of Materials) without compromising the excellent performance of cemented carbide. 【Product Information】 ■Cemented Carbide - For TA tips - For brazed tools - For wear-resistant tools, etc. ■Cemented Carbide Tools (Solid & Brazed) - TA tips - Wear-resistant tools - Knives, etc. *For more details, please download the PDF or contact us.

Special shape reamer made of ultra-hard alloy for equilateral triangles! Achieves high-precision hole finishing for brittle materials with high coaxial accuracy through one-chuck processing!
We would like to introduce the "Triangular Prism Reamer Pin" handled by Sanwa Creation Co., Ltd. It has been manufactured for hole processing in highly brittle materials where standard tools cannot be used. The cutting edge is in the shape of an equilateral triangle. Since the triangle is formed with a single chuck, the axial misalignment with the shank is within 1µm. Application: It is used for high-precision finishing of holes in the jewelry field. Orders can be placed in small lots, and detailed size specifications are also possible.
We will also introduce product examples that leverage a high young's modulus! Information on its use in internal grinding processing is also included.
This document explains the rigidity of cemented carbide and cemented carbide quills in the newsletter "THE TOUEI TIMES" published by Toei Super Hard Co., Ltd. Cemented carbide has various characteristics, and this issue introduces Young's modulus (rigidity). There are also product examples that utilize high Young's modulus. Additionally, you can see how our cemented carbide quills are used for internal grinding, so please make use of this information when considering implementation.
