Key Considerations for Using Tungsten Carbide Parts: What You Need to Know!

In the vast realm of the hardware industry, tungsten carbide parts occupy an indispensable position with their unique properties, widely utilized across various mechanical fields. Today, Yize’s editor will meticulously outline the crucial points that must be taken into account when using tungsten carbide parts, helping you navigate the intricacies of this industrial treasure with ease.

1. Surface Condition: The Invisible Guardian of Bending Strength
   The surface condition of tungsten carbide parts serves as a barometer for their bending strength. In every step of crafting tungsten carbide tools, vigilance against any minute cracks is imperative, as they can become invisible assassins weakening the strength of tungsten carbide. Maintaining a flawless surface is key to ensuring the robustness of tungsten carbide parts.
2. Brittleness Characteristic: Handle with Care, Avoid Impact
   Tungsten carbide parts are renowned for their high brittleness, a trait unrelated to temperature. Even at room temperature, their impact toughness is significantly lower than that of quenched steel, with a gap of 1-2 times. Therefore, when handling or brazing tungsten carbide, remember to treat it gently, avoiding any form of impactful compaction. Additionally, during transportation, care should be taken to prevent collisions that could cause damage.
3. Linear Expansion Coefficient: The Delicate Balance in Brazing Processes
   A deep understanding of tungsten carbide’s linear expansion coefficient is fundamental to mastering the art of its brazing. Compared to high-speed steel, tungsten carbide’s linear expansion coefficient is more than half as low. This difference is particularly critical during the brazing process. Upon cooling, due to the disparate expansion coefficients, the inner and outer layers of the mold will endure different stresses, resulting in inward tensile stresses on the surface. Therefore, stress relief measures after brazing are of utmost importance; otherwise, cracks or brazing failures may unexpectedly occur, compromising the perfect performance of tungsten carbide parts.

In summary, the use and maintenance of tungsten carbide parts require meticulous attention to detail in order to maximize their performance. It is hoped that this guide will serve as a valuable assistant on your tungsten carbide application journey, empowering you to excel in the hardware field with confidence and skill.
