Tungsten carbide has very high hardness and excellent wear resistance, and is widely used in drills, tools, molds, needles, knives and other industries that require wear resistance and special processing. Due to the high bonding strength and fine microstructure of tungsten carbide particles and metal binder phase, ultra-fine cemented carbide combines the characteristics of ceramics and metals at the same time, and has high toughness, high degree of hardness, and high hardness. As far as the specific data is concerned, the hardness is 2% to 3% higher, and the room temperature tensile strength is 30% to 40% higher. Even at a slightly higher temperature, the hardness of ultra-fine-grained cemented carbide will not be obvious. decline. Because it can be made into a sharp edge, at present, this type of material not only has obvious advantages in the application of difficult-to-machine materials, but also occupies an extremely important position in the high-tech field, and is widely used in various micro tools and wear-resistant parts, such as Micro-drilling for circuit board processing, etc.
