Due to their high hardness, high wear resistance, high compressive strength, and excellent bending resistance, tungsten cemented carbide balls are widely used in key applications such as high-load precision bearings, oilfield valve ball seals, and high-temperature mold components. Their strength characteristics stem from the combined effects of material composition, microstructure, and process control, as analyzed below:

Tungsten cemented carbide balls are characterized by high hardness, high compressive strength, moderate flexural strength, low impact toughness, and excellent wear and corrosion resistance. This comprehensive combination of mechanical properties makes them an ideal material for high-load, harsh working conditions.

The excellent oxidation resistance of tungsten cemented carbide balls is primarily due to their material properties and optimized composition.

The excellent chemical stability of tungsten cemented carbide balls stems primarily from their unique material composition and powder metallurgy process, as demonstrated below:

The impact resistance test of tungsten cemented carbide balls is an important method to evaluate their ability to resist damage when subjected to external force impact, and is usually used to test the strength, toughness and durability of tungsten cemented carbide balls.

I. Impact Resistance of Tungsten Cemented Carbide Balls 

Tungsten cemented carbide balls are made from a carbide matrix such as tungsten carbide (WC) or titanium carbide (TiC), sintered with a binder such as cobalt (Co), nickel (Ni), or molybdenum (Mo). Their impact resistance is primarily reflected in the following aspects:

Tungsten cemented carbide balls are high-performance powder metallurgy products. They are primarily composed of tungsten carbide (WC), a high-hardness, refractory metal, with cobalt (Co), nickel (Ni), or molybdenum (Mo) as a binder, and are sintered in a vacuum furnace or hydrogen reduction furnace. Common series include YG, YN, YT, and YW. This material is highly valued for its excellent hardness, wear resistance, and corrosion resistance, while thermal stability is one of its core advantages in high-temperature environments.

Tungsten cemented carbide balls exhibit excellent fatigue resistance, which is significantly affected by composition, processing, and operating conditions. A high binder phase content, nickel-chromium additions, and optimized processing significantly enhance fatigue resistance, making them suitable for long-term stable operation under high-load, complex environments.

The compressive strength of tungsten cemented carbide balls is their ability to resist failure under compressive loads and is a key indicator for evaluating their performance.

Tungsten cemented carbide balls are primarily composed of tungsten carbide (WC) powder as the main component, with metals such as cobalt (Co), nickel (Ni), or molybdenum (Mo) as binders, manufactured through powder metallurgy processes such as vacuum sintering. This composite material, due to its unique microstructure, performs exceptionally well in high-temperature environments, effectively resisting thermal deformation and oxidation. It is widely used in high-temperature and high-pressure applications such as the petroleum, chemical, and aerospace industries.
