China Tungsten Carbide Ball Manufacturer
Cemented Tungsten Carbide, a remarkable material crafted by expert tungsten carbide ball manufacturers, is truly incredible. It was originally pioneered by these manufacturers for utilization as a cutting-edge tool in machine tool applications, where it continues to enjoy widespread adoption today. With a hardness rating of 91 HRA, equivalent to 1500 Vickers 30, this material is exceedingly hard, a testament to the precision and craftsmanship of tungsten carbide ball manufacturers.
Its exceptional wear-resistance, demonstrated in abrasion tests where it outperforms hard steel by a factor of 30, underscores the durability and longevity offered by tungsten carbide ball manufacturers' products. Furthermore, the material's outstanding long-term dimensional stability renders it an ideal choice for gage applications, ensuring accuracy and precision in even the most demanding scenarios.
The stiffness of cemented tungsten carbide, boasting Young's modulus of elasticity of 98,000,000 pounds per square inch compared to steel's 30,000,000 PSI, is another testament to the superior engineering capabilities of tungsten carbide ball manufacturers. This high stiffness makes tungsten carbide balls, crafted by these manufacturers, an exceptional choice for ball-sizing applications, delivering premier results as components of kinematic couplings.
Moreover, tungsten carbide ball manufacturers' products excel in high-temperature environments, maintaining their performance up to 800 degrees Fahrenheit (427° Centigrade), making them a reliable choice for applications where temperature resistance is crucial. In summary, the exceptional properties of cemented tungsten carbide, as produced by tungsten carbide ball manufacturers, make it an invaluable material across various industries.
Tungsten carbide ball manufacturers pride themselves on producing a material that boasts exceptional corrosive resistance across numerous environments. This material, renowned for its low thermal expansion rate of 2.5 microinches per inch per degree Fahrenheit (4.9 X 10^-6 per degree C), significantly outperforms steel (6.4 micro inches) and aluminum (12 micro inches) in this regard.
One of the pivotal features of tungsten carbide balls crafted by these manufacturers is their electrical conductivity, with a resistivity of two micro-ohms per centimeter. This unique property sets them apart from other rigid materials like ceramics and sapphire, enabling them to be intricately shaped through the electrical discharge machining (EDM) process. Tungsten carbide ball manufacturers' expertise in this area ensures precision and versatility in the fabrication of these balls.
Moreover, tungsten carbide balls can be refined using diamond grit, underscoring the durability and resilience of the material. The slight magnetic nature of these balls, attributed to the metallic binder (typically nickel or cobalt) used in their production, allows for the convenient pickup of small-diameter balls with a magnet.
Tungsten carbide ball manufacturers also emphasize the material's substantial weight, with a density of .54 pounds per cubic inch or 15 grams per cubic centimeter. It's important to note that cemented tungsten carbide is neither purely a metal nor a ceramic but rather a cermet, a term that, although not widely used, accurately describes its unique composition of Tungsten Carbide ceramic particles bonded by a metallic binder to form a solid, durable mass. Tungsten carbide ball manufacturers' deep understanding of this material's properties enables them to create products that meet the most stringent requirements across various industries.
Making the Tungsten Carbide Raw Material
Tungsten carbide ball manufacturers employ a sophisticated process to transform a blend of powdered tungsten metal and carbon powder into tungsten carbide (WC). Using the power of an electric arc, the mixture is heated to an extremely high temperature while contained within a carbon crucible. This intense heat facilitates a complete chemical reaction between the two elements, resulting in the formation of a substantial lump of tungsten carbide. This lump then undergoes a rigorous crushing and milling process to yield a fine, evenly-sized powder, which is carefully screened to ensure uniform particle dimensions.
Processing the Ball Blank
Tungsten carbide ball manufacturers meticulously blend the tungsten carbide powder with powdered cobalt metal, creating a homogeneous mixture. To this blend, a polymer or wax is introduced, serving as a crucial mechanical binder during the pre-sintered stage. A precisely measured amount of this combined powder is then compressed under the force of a double-acting press, shaping it into the tungsten carbide ball blank, also known as the pre-form.
To refine this pre-form, tungsten carbide ball manufacturers utilize a vacuum chamber, where the binder is eliminated through a process of outgassing. As the temperature rises, the binder is released as a liquid and captured downstream. Subsequently, the tungsten carbide and cobalt pre-forms are sintered or fused into a dense, solid mass within a high-temperature vacuum or hydrogen atmosphere furnace. This intricate process, carried out by skilled tungsten carbide ball manufacturers, ensures the production of high-quality tungsten carbide balls with exceptional properties.
Some tungsten carbide ball sizes are hot isocratic pressed or hipped. The newest method is to Sinter-HIP the parts in one operation. The metallurgically complete ball blanks are then rough ground with coarse diamond to remove any imperfections on the surface. They are then finished lapped and polished with micro-size diamond dust to final size, microinch roundness, and a sub-microinch surface finish.
Chemical Analysis for Tungsten Carbide Ball Manufacturers:
Performing spectrographic chemical analysis on tungsten carbide (T.C.) can pose significant challenges and uncertainties for tungsten carbide ball manufacturers. To mitigate these complexities, the industry has widely adopted the use of magnetic dermoscopic evaluation as the standard procedure. It is essential to remain skeptical of claims that promise exact analysis results, as the inherent variability in T.C.'s composition necessitates a discussion of the error budget associated with the analysis process. Reputable tungsten carbide ball manufacturers will be transparent about the percentage-based uncertainty in their analyses.
Understanding the limitations of T.C.'s chemical and physical properties is crucial for tungsten carbide ball manufacturers. Unlike alloy metals, T.C. is a physical blend of pure metal powder and powdered ceramic, resulting in inherent variability in its performance. This variability is a natural consequence of its composition and must be taken into account during manufacturing and application.
Furthermore, tungsten carbide ball manufacturers must recognize that the stiffness or Young's modulus of elasticity, typically measured in tension, may not directly translate to the compressive environment in which tungsten carbide balls are predominantly used. Therefore, tungsten carbide ball manufacturers must carefully consider these factors when designing and producing their products to ensure optimal performance and reliability.
Special grades of tungsten carbide
The hard metals industry has seen tremendous consolidation. The surviving entities have grown into very large corporations that are far less willing to produce any unique combinations of material orders. This has significantly reduced the availability of special grades of cemented tungsten carbide. Many exotic grades are simply unavailable today.
