The friction coefficient of tungsten cemented carbide balls depends on the contact material, surface roughness, lubrication conditions, and environmental factors (such as temperature and humidity). The following is an overview of the friction coefficient of tungsten cemented carbide balls:

Tungsten cemented carbide balls are spherical products made from tungsten carbide (WC) powder as the primary component and cobalt (Co) or other metals as a binder, sintered using a powder metallurgy process. They offer high hardness, wear resistance, corrosion resistance, bending resistance, and high-temperature resistance, making them widely used in precision bearings, valve seals, abrasive media, instrumentation, sprayers, water pumps, oilfield equipment, and hardness testers.

Tungsten cemented carbide balls are spherical products made by sintering refractory metal tungsten carbide (WC) powder as the primary component, with cobalt (Co) or nickel (Ni) as the binder, using a powder metallurgy process. The formation of internal stress is primarily due to microstructural heterogeneity during material preparation. The specific mechanisms and impacts are as follows:

Tungsten cemented carbide balls are powder metallurgy products made from a matrix of high-hardness, refractory tungsten carbide powder, with cobalt (Co), nickel (Ni), or molybdenum (Mo) as a binder, sintered in a vacuum furnace or hydrogen reduction furnace. Their hardness characteristics and key influencing factors are as follows:
