What is a Cemented carbide?

Cemented carbide, also known as tungsten carbide, is a highly durable and wear-resistant metal material. It is created by mixing metal powders, primarily tungsten carbide (WC) and cobalt (Co), and then pressing and sintering them at high temperatures. This process produces an alloy with exceptional hardness and resistance to wear. Cemented carbide is widely used in cutting tools, drill bits, milling cutters, molds, dies, and other components exposed to harsh conditions. Its hardness makes it ideal for metalworking, mining, and civil engineering applications, as well as high-speed rotating parts and machinery contact surfaces. Cemented carbide is highly resistant to heat, acids, and alkalis, maintaining its high performance over long periods. Due to its difficulty in machining, precise shaping of the material requires advanced technical expertise.

Application of Cemented carbide

１．Cutting Tools: Cemented carbide is commonly used in the manufacturing of cutting tools such as drill bits, milling cutters, and turning tools due to its hardness and wear resistance.
２．Mining Equipment: It is widely used for tools and components involved in mining operations, such as rock drilling bits and mining machinery parts, because of its ability to withstand the tough conditions.
３．Molds and Dies: Cemented carbide is used in the production of molds and dies for metalworking, plastic injection molding, and forging due to its durability and high resistance to wear and heat.
４．Aerospace: Certain aerospace components, like turbine blades and nozzle components, are made from cemented carbide because of its excellent heat resistance and durability under extreme conditions.
５．Cutting-edge Machinery: In manufacturing, high-speed machining tools that require sharp precision often utilize cemented carbide because of its ability to retain sharpness over extended use.
