Tungsten Carbide Bars Widely Application
Within the broad family of industrial materials, cemented carbide strips are a type of material characterized by their unique form and superior performance. Visually, they take the form of long strips with a relatively high length-to-width-to-thickness ratio; this distinctive shape enables them to play an irreplaceable role in numerous industrial applications.
Cemented carbide strips are a derivative product of cemented carbide materials. They inherit the core characteristics of cemented carbide while offering specific application advantages due to their unique form. Compared to other forms of cemented carbide products...
II. Material Composition of Cemented Carbide Rods
The exceptional performance of cemented carbide rods bar stems from their unique material composition, which consists primarily of refractory metal compounds and a binder metal.
Refractory metal compounds form the framework of cemented carbide rods, with tungsten carbide being the most commonly used. Tungsten carbide possesses extremely high hardness and a high melting point, enabling cemented carbide rods to maintain stable performance under high-temperature, high-pressure, and high-friction conditions. In addition to tungsten carbide, other refractory metal compounds such as titanium carbide and tantalum carbide may be added depending on specific application requirements. The inclusion of these compounds allows for the adjustment of the cemented carbide rod’s properties, such as enhancing its wear resistance and oxidation resistance.
The binder metal serves to bind the refractory metal compound particles together; commonly used types include cobalt and nickel. The content and type of binder metal directly affect the toughness and strength of the cemented carbide rod. As a commonly used binder metal, cobalt forms a strong bond with refractory compounds such as tungsten carbide, enabling the cemented carbide rods to possess both high hardness and a certain degree of toughness, thereby preventing fracture due to excessive brittleness during use. Nickel, on the other hand, is selected for applications requiring corrosion resistance; it enhances the corrosion resistance of the cemented carbide rods, thereby expanding their range of applications.
The ratio between refractory metal compounds and the binder metal requires precise calculation and formulation. Different ratios can result in significant variations in the performance of cemented carbide bars. Generally, the higher the content of refractory metal compounds, the better the hardness and wear resistance of the cemented carbide bar, but its toughness will be relatively reduced; conversely, when the binder metal content increases, toughness and strength improve, but hardness and wear resistance decrease. Therefore, during the production process, the appropriate material ratio is determined based on specific application scenarios and performance requirements to achieve a balance of properties.
III. Production Process of Cemented Carbide Bars
The production of cemented carbide bars is a complex and precise process, with every step having a significant impact on the performance of the final product. The production process primarily includes steps such as powder preparation, mixing, pressing, and sintering.
