Precision tungsten carbide is a cemented carbide material made primarily of tungsten carbide (WC), combined with metal binders such as cobalt (Co) and nickel (Ni), using powder metallurgy.
Product Introduction
Composition and Structure: The main component is tungsten carbide, which provides high hardness and wear resistance. The metal binder holds the tungsten carbide particles together, giving the material a certain degree of toughness and strength. By controlling the powder particle size, binder content, and sintering process, precision tungsten carbide with different properties can be obtained.
Performance Characteristics
High Hardness: Hardness can reach 89-95 HRA, far exceeding that of ordinary steel, maintaining sharpness for a long time and suitable for high-precision cutting.
High Wear Resistance: Maintains excellent wear resistance even under high temperature and high pressure environments, significantly extending the service life of tools and parts.
High Strength and Toughness: Possesses good strength and toughness, able to withstand significant impacts and loads, and is not easily broken.
Heat Resistance: Maintains good cutting performance even at 500ºC, exhibiting high stability in high-temperature environments.
Corrosion Resistance: Excellent resistance to corrosive media such as acids and alkalis, suitable for harsh working environments.
Product Forms:
* Tungsten Carbide Rods: Primarily used for manufacturing drill bits, automotive cutting tools, printed circuit board cutting tools, etc., and can also be used to make punches, mandrels, etc.
* Tungsten Carbide Sheets: Primarily used for manufacturing various metal and non-metal cutting tools, wear-resistant tools, as well as high-speed stamping dies and multi-station progressive dies.
Application Areas:
* Machining: In metal cutting, tungsten carbide tools dominate, suitable for machining difficult-to-cut materials such as cast iron, stainless steel, and heat-resistant steel. In mold manufacturing, tungsten carbide molds achieve grain refinement through powder metallurgy, with bending strength reaching over 3000MPa, commonly used in high-precision stamping dies, wire drawing dies, etc.
* Energy Extraction: In oil drilling, tungsten carbide drill bits, through optimized cobalt content and tungsten carbide grain size, can operate in high-pressure, high-temperature, and highly corrosive environments thousands of meters underground. In mining machinery, tungsten carbide drill bits are core components in rock drilling operations. Utilizing isostatic pressing, they exhibit excellent density uniformity and a long service life.
In electronics: In the semiconductor industry, tungsten carbide, through vacuum sintering, can control impurity content to below 50 ppm, meeting the precision requirements of wafer dicing and chip packaging. In 5G communications, tungsten carbide electrode rods play a crucial role in precision electrical discharge machining; their balanced design of conductivity and thermal conductivity meets the manufacturing requirements of millimeter-wave antenna filters.
In healthcare: In minimally invasive surgery, tungsten carbide needles, due to their high hardness and biocompatibility, have become the preferred tool for arthroscopic and laparoscopic surgeries. In dental implantology, tungsten carbide burs, formulated with ultra-fine grains and a special cobalt-based binder, exhibit improved fatigue resistance and can operate at high speeds of 400,000 revolutions per minute.
In the new energy sector: In lithium-ion battery electrode cutting, tungsten carbide blades, through laser cladding technology, form a tungsten carbide-nickel gradient coating, which can control the cutting burr height to within 3μm, reducing battery internal resistance and improving cycle life. In the processing of bipolar plate flow channels for hydrogen fuel cells, tungsten carbide end mills can achieve precise microchannel forming.
