Tungsten Carbide EDM Blocks are carefully fabricated through the powder metallurgy process. They use refractory metal carbides such as tungsten carbide (WC) as the hard phase. These hard phases are like solid cornerstones, endowing the alloy plates with extremely high hardness and wear resistance. Meanwhile, metals like cobalt (Co) and nickel (Ni) serve as the binder phase, closely connecting the hard phase particles and ingeniously adding necessary toughness to the alloy plates, making them both rigid and flexible and avoiding the risk of brittleness due to excessive hardness.
 
When it comes to properties, the high hardness of tungsten carbide EDM blocks is remarkable. Their hardness values far exceed those of ordinary metal plates, with Rockwell hardness (HRA) ranging from 85 to 92. This means that they can remain calm and maintain the stability of their own shape and size when facing various high-intensity friction, cutting, and wear conditions, and are not prone to scratches or damage. For example, in the field of metal cutting processing, if used as a tool material, it can maintain sharp cutting edges for a long time, continuously cut a large number of metal workpieces, greatly improving processing efficiency and ensuring processing accuracy.
 
High wear resistance is also a highlight of tungsten carbide EDM blocks. During long-term use, the surface wear of them is extremely small. Just like the tungsten carbide EDM blocks used as rollers in textile machinery, which need to work in an environment of high-speed operation and continuous friction. However, relying on their excellent wear resistance, they can play a stable role for a long time, reducing the downtime and costs caused by frequent component replacements and providing strong support for the continuity of textile production.
 
Moreover, tungsten carbide EDM blocks have good compressive strength and can withstand relatively large pressures without being easily deformed or fractured. In terms of mold manufacturing, such as stamping molds and cold heading molds, they can still ensure the accuracy of the mold cavity under the condition of withstanding huge impact and extrusion forces, making the produced parts have accurate dimensions and consistent shapes, laying a solid foundation for high-quality mass production.
 
In addition, tungsten carbide EDM blocks also have relatively good chemical stability and have a certain tolerance for common corrosive substances such as acids and alkalis, which enables them to be reliably applied in relatively complex chemical environments and broadens their application range.
 
In practical applications, tungsten carbide EDM blocks can be seen everywhere. In the cutting processing field, they are made into various cutting tools, such as turning tools, milling tools, drill bits, etc., helping metal processing to be more efficient and accurate. Whether it is processing ordinary steel or high-hardness alloy steel, they can handle it with ease. In the mold manufacturing field, they are an indispensable ideal material, injecting strong vitality into stamping, cold heading, die-casting and other kinds of molds, ensuring the durability of the molds and the stability of production. Meanwhile, in many machines that require wear-resistant components, such as guide rollers in printing machinery, tungsten carbide EDM blocks extend the service life of components and reduce the maintenance costs of equipment by virtue of their wear-resistant characteristics.
 
In conclusion, tungsten carbide EDM blocks, with their excellent properties, have become a powerful assistant in the industrial field, continuously promoting the vigorous development of various industries towards high quality and high efficiency, and will surely show their unique value in more innovative applications in the future.
