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.

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.

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 use carbides (such as WC, TiC) as hard phase and metal binders (such as Co, Ni) as bonding phase. Their corrosion resistance mechanism comes from the chemical inertness of the hard phase, the optimization of the corrosion resistance of the bonding phase and the synergistic inhibition.
