Cemented carbide blades are made of cemented carbide, which is an alloy material made of hard compounds of refractory metals and bonding metals through powder metallurgy.
Cemented carbide has a series of excellent properties such as high hardness, wear resistance, good strength and toughness, heat resistance and corrosion resistance, especially its high hardness and wear resistance, which basically remain unchanged even at a temperature of 500°C , It still has high hardness at 1000 °C.
Tungsten carbide blades, also known as tungsten steel blades, are electronic industry blades made of cemented carbide, that is, tungsten steel.
Carbide inserts are mainly made of solid carbide as the substrate, and are finished through multiple production processes.
Cemented carbide, also known as tungsten steel, is made of high-quality tungsten carbide + cobalt powder mixed in a formula and then pressed and sintered. It has high hardness, high strength, high wear resistance and high elastic modulus, and belongs to the powder metallurgy industry. . As the teeth of modern industry, cemented carbide tools play a fundamental role in promoting the development of the manufacturing industry.
Cemented carbide can be divided into ordinary cemented carbide, fine-grained cemented carbide, sub-fine and ultra-fine grained cemented carbide according to the grain size, and the newly launched double crystal cemented carbide. 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 carbide includes three types of tungsten-cobalt (YG), tungsten-cobalt-titanium (YT) and rare carbides (YW), each of which has its own advantages and disadvantages. The main components are tungsten carbide (WC), titanium carbide ( Tic), niobium carbide (NbC) and other commonly used metal binder phase is Co. Titanium carbide-based cemented carbide is a cemented carbide with Tic as the main component, and the commonly used metal binder phases are Mo and Ni. Cemented carbide has high hardness (86-93HRA, equivalent to 69-81HRC) second only to diamond, good thermal hardness (up to 900-1000°C, maintaining 60HRC); high bending strength (MPa5100), good impact toughness And chemical inertness with high corrosion resistance and other characteristics that general alloy blades do not have.
