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.

Tungsten cemented carbide balls are precision spherical products manufactured through a powder metallurgy process using tungsten carbide (WC) powder as the primary component and a metal binder such as cobalt (Co), nickel (Ni), or molybdenum (Mo). Common grades include the YG, YN, YT, and YW series. This material is renowned for its high hardness (typically ≥90.5 HRA) and high density (approximately 14.9 g/cm³). Its excellent corrosion resistance makes it particularly suitable for use in harsh chemical environments, such as oil production, chemical valves, and hydrochloric acid laboratories.

The wear resistance test of tungsten cemented carbide balls is an important means to evaluate their wear resistance under specific working conditions. It is often used in oil drilling, mining machinery, cutting tools and other fields.

Tungsten cemented carbide balls possess exceptional wear resistance, tens to hundreds of times greater than that of traditional steel balls. They can operate stably and long-term under harsh conditions such as high loads, high speeds, and severe corrosion, significantly reducing equipment wear and maintenance costs.

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 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 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 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:

The tolerance requirements for tungsten cemented carbide balls typically vary depending on the application, industry standards, and manufacturing process. The following are some common requirements and explanations for tungsten cemented carbide ball tolerances, based on international or industry standards (such as ISO, DIN, ANSI, etc.) and typical application scenarios:

Tungsten cemented carbide balls (typically made with a metal binder such as tungsten carbide and cobalt) are widely used in high-precision, demanding applications due to their exceptional hardness, wear resistance, corrosion resistance, and stability. Their dimensional accuracy is one of the core criteria for measuring their quality.
