Cemented carbide, also known as hard alloy, is a composite material made primarily of tungsten carbide (WC) particles bonded with a metallic binder such as cobalt or nickel. Owing to its exceptional hardness, high wear resistance, and excellent toughness, cemented carbide is widely used in various industrial applications. In the machining industry, it is the key material for cutting tools, drills, milling cutters, and inserts used for high-speed and precision machining of metals, composites, and other hard materials. In the mining and construction sectors, cemented carbide is used to manufacture drilling bits, rock-cutting tools, and wear-resistant components that operate under extreme conditions. It is also applied in the mold and die industry for producing forming tools and dies that require high durability. Additionally, cemented carbide plays a vital role in aerospace, automotive, and energy industries, where it contributes to improved efficiency and extended service life of components exposed to high temperatures, friction, and pressure. Thanks to its superior performance and reliability, cemented carbide remains one of the most important materials supporting modern manufacturing and engineering innovation.
