.> It consists of two parts: one part is the hardened phase and the other part is the bonding metal. The bonding metal is generally an iron group metal, with cobalt, nickel and titanium being commonly used. Therefore, there are tungsten-cobalt alloys, tungsten-nickel alloys and tungsten-titanium-cobalt alloys. Steels containing tungsten, such as high-speed steel and some hot work die steels, contain tungsten in the steel, which can significantly improve the hardness and heat resistance of the steel, but the toughness will drop sharply.

Carbide is widely used as tool materials, such as turning tools, milling cutters, planers, drill bits, boring tools, etc., for cutting cast iron, non-ferrous metals, plastics, chemical fibers, graphite, glass, stone and ordinary steel, and can also be used for cutting Heat-resistant steel, stainless steel, high manganese steel, tool steel and other difficult-to-process materials. The cutting speed of new carbide tools is now hundreds of times that of carbon steel.

But the harder the material, the lower its flexural strength and impact toughness. High-speed steel is still the most widely used material due to its high bending strength, impact toughness, and good processability, followed by cemented carbide. The materials made must have high high temperature hardness and wear resistance, necessary bending strength, impact toughness and chemical inertness, and good processability

.>Cemented carbide round rods are made of high-quality ultra-fine tungsten carbide and imported cobalt powder as raw materials, and are produced in a standardized manner using the world's advanced low-pressure sintering preparation technology. They have good wear resistance and resistance to Bending strength, can be used to make various drill bits, special tools for automobiles, special tools for printed circuit boards, special tools for engines, special tools for watch processing, integral end mills, integral reamers, engraving knives, etc. Tungsten steel sintering molding is to The powder is pressed into a billet, then heated to a certain temperature (sintering temperature) in a sintering furnace, maintained for a certain period of time (heat holding time), and then cooled down to obtain the tungsten steel material with the required properties.

.Basic knowledge of cemented carbide processing
.>The materials manufactured must have high high temperature hardness and wear resistance, necessary bending strength, impact toughness and chemical inertness , good processability (cutting, forging and heat treatment, etc.), and not easy to deform.
. Usually when the hardness of the material is high, the wear resistance is also high. When the bending strength is high, the impact toughness is also high. But the harder the material, the lower its flexural strength and impact toughness. High-speed steel is still the most widely used material due to its high bending strength, impact toughness, and good processability, followed by cemented carbide.
Polycrystalline cubic boron nitride is suitable for cutting high-hardness hardened steel and hard cast iron. Polycrystalline diamond is suitable for cutting iron-free metals, as well as alloys, plastics, fiberglass and other carbon tool steels and alloy tool steels. Only used as tools such as files, dies and taps.
The carbide indexable inserts of Dongguan Gaoda Copper and Aluminum Company are now coated with titanium carbide, titanium nitride, aluminum oxide hard layer or composite hard layer using chemical vapor deposition method. The developing physical vapor deposition method can be used not only for cemented carbide, but also for high-speed steel, such as drill bits, hobs, taps and milling cutters. The hard coating acts as a barrier that hinders chemical diffusion and heat conduction, slowing down the wear rate during cutting. The life of the coated blade is approximately ~ times longer than that of the uncoated blade.
Generally, the durability of steel depends on the red hardness, wear resistance and impact toughness of the material. When the cobalt content in the quasi-cemented alloy is high, the bending strength and impact toughness are good, especially the fatigue strength is improved, so it is suitable for rough machining under impact and vibration conditions. When the cobalt content is small, its hardness , high wear resistance and heat resistance, suitable for continuous cutting and finishing.
