long carbide blade, cemented carbide, diffusion bonding
Cemented carbide is known as having high melting point and extremely hard material. However, manufacturing a long tool was limited due to such characters. Then, we established the manufacturing technology of long carbide tools by using diffusion bonding, and produce them on a commercial basis. The long carbide products are applied to blades etc, showing excellent durability (abrasion resistance) compared with steel blades with high quality.
