Cemented carbide bars are a high-performance alloy material made of hard compounds of refractory metals and bonding metals through powder metallurgy. Its excellent physical and mechanical properties make it widely used in many industrial fields.
Cemented carbide bars are known for their high hardness, which is much higher than ordinary steel. Even at high temperatures (such as 500°C), its hardness remains basically unchanged, and it still has a high hardness at 1000°C. This high hardness property makes cemented carbide bars perform well in applications such as cutting and grinding, and can maintain the sharpness of the cutting edge for a long time, reduce wear and increase service life. At the same time, cemented carbide bars also have good wear resistance and can maintain stable performance for a long time in harsh working environments.
Cemented carbide bars not only have high hardness, but also have good strength and toughness. Its strength is enough to withstand large cutting forces and impact forces, and it is not easy to break or deform. Toughness enables cemented carbide bars to absorb more energy when impacted, reducing the risk of brittle fracture. This combination of high strength and toughness makes cemented carbide bars perform well under complex working conditions such as heavy loads and high-speed cutting.
Cemented carbide bars can still maintain good mechanical properties at high temperatures and are not prone to softening and deformation. This gives cemented carbide bars a significant advantage when cutting high-temperature materials (such as heat-resistant steel, stainless steel, etc.). At the same time, the heat resistance of cemented carbide bars also enables them to work stably for a long time in high-temperature environments, extending their service life.
Cemented carbide bars have good corrosion resistance and can resist the erosion of various corrosive media such as acids, alkalis, and salts. This makes cemented carbide bars widely used in corrosive environments such as chemicals and petroleum. At the same time, corrosion resistance also improves the anti-aging properties of cemented carbide bars and extends their service life.
Cemented carbide bars have stable mechanical properties, thanks to their uniform microstructure and good process control. During the manufacturing process, the cemented carbide bars can be ensured to have consistent physical and mechanical properties through precise powder proportioning, mixing, pressing and sintering process steps. This stability makes cemented carbide bars more reliable and consistent in mass production and application.
Cemented carbide bars have good machinability and weldability. Through appropriate processing methods (such as turning, milling, grinding, etc.), they can be processed into various shapes and sizes of tools, molds and other parts. At the same time, cemented carbide bars can also be welded or connected with other materials to form composite structures or tools to meet specific application requirements.
With its excellent physical and mechanical properties, cemented carbide bars are widely used in many fields such as metal cutting, mining, oil drilling, and mold manufacturing. In the field of metal cutting, cemented carbide bars are used as tool materials, which can cut various metal materials efficiently and accurately. In the fields of mining and oil drilling, cemented carbide bars are used as drill bits and cutting tools, which can cope with harsh working conditions and complex geological conditions. In the field of mold manufacturing, cemented carbide bars are used as mold materials, which can significantly improve the wear resistance and service life of the mold.
Cemented carbide bars have excellent physical and mechanical properties, including high hardness, wear resistance, high strength, toughness, heat resistance, corrosion resistance and stable mechanical properties. These properties make cemented carbide bars widely used in many industrial fields and become one of the indispensable important materials in modern industry.
