Tungsten carbide sheetIt is a hard alloy product made from tungsten carbide powder as the main raw material, added with binders such as cobalt and nickel, and pressed and sintered. With outstanding characteristics such as high hardness, strong wear resistance, and high temperature resistance, it plays an important role in industrial fields such as mechanical processing, mining, and aerospace, and has become a reliable tool for dealing with harsh working conditions.
Ultra high hardness and excellent wear resistance are its core characteristics. The hardness of tungsten carbide itself is second only to diamond and cubic boron nitride. After sintering, the hardness of tungsten carbide sheets can reach HRA85-93, far higher than ordinary steel and high-speed steel. In the field of mechanical processing, tools made of tungsten carbide sheets can easily cut difficult to machine materials such as quenched steel and stainless steel, with a cutting life 5-10 times that of high-speed steel tools; In mold manufacturing, stamping dies and drawing dies made of tungsten carbide sheets can withstand high-frequency stamping and stretching operations, are not easily worn or deformed, and greatly improve the service life of molds and product processing accuracy.
Excellent high temperature resistance and corrosion resistance broaden application scenarios. The melting point of tungsten carbide sheet is as high as 2870 ℃, and it can maintain stable mechanical properties in high temperature environments. It can be used to manufacture support components and thermocouple protective sleeves in high-temperature furnaces; It has strong chemical stability and can resist the erosion of corrosive media such as acids, alkalis, and salts. It is commonly used as corrosion-resistant lining, valve seals, etc. in chemical equipment. In mining, mining tools embedded with tungsten carbide sheets can operate continuously in harsh environments with high wear and impact, effectively improving mining efficiency.
Good strength and toughness achieve a balance of performance. Compared to the brittleness of pure tungsten carbide, tungsten carbide sheets with added binders have both high strength and certain toughness, avoiding easy fragmentation under impact. In the aerospace field, tungsten carbide sheets are used to manufacture turbine blades, combustion chamber components, etc. for engines, which can withstand high temperature and high pressure working environments, as well as resist stress caused by airflow impact; In medical devices, surgical instruments made of tungsten carbide sheets are not only sharp and wear-resistant, but also have good biocompatibility, meeting the requirements of medical use.
