Material properties:

The cemented carbide blade is mainly made of the whole cemented carbide as the base material, which is processed through a number of production processes.

Cemented carbide, also known as tungsten steel, is made of high-quality tungsten carbide + cobalt powder by pressing and sintering after mixing the formula. It has high hardness, high strength, high wear resistance and high elastic modulus. It belongs to powder metallurgy industry. As the teeth of modern industry, cemented carbide cutting tools play a fundamental role in promoting the development of manufacturing industry.

The cemented carbides can be divided into ordinary cemented carbides, fine-grained cemented carbides and sub-fine and ultra-fine-grained cemented carbides according to the grain size, and the newly developed double-crystal cemented carbides. According to the main chemical composition, it can be divided into tungsten carbide-based cemented carbide and titanium carbide-based cemented carbide. Tungsten carbide-based cemented carbides include tungsten-cobalt (YG), tungsten-cobalt-titanium (YT) and rare carbides (YW). They have their own advantages and disadvantages. The main components are tungsten carbide (WC), titanium carbide (Tic), niobium carbide (NbC), and other commonly used metal bonding phases are Co. TiC-based cemented carbide is a kind of cemented carbide with Tic as its main component. The commonly used metal bonding phases are Mo and Ni. Cemented carbide has the characteristics of high hardness (86-93 HRA, equivalent to 69-81 HRC), second only to diamond, good thermal hardness (up to 900-1000 C, maintaining 60 HRC), high flexural strength (MPa5100), good impact toughness and chemical inertia with high corrosion resistance.
