YG6 Tungsten Carbide Spheres

YG6 tungsten carbide spheres are precision-engineered high-hardness and wear-resistant spheres made from a cemented carbide alloy containing 94% tungsten carbide (WC) and 6% cobalt (Co). This composition provides an excellent balance of hardness, toughness, and wear resistance, making them ideal for applications requiring high impact strength, superior durability, and precision performance.

Key Features:

✅ High Hardness – With a Rockwell Hardness (HRA) of ~90, YG6 carbide spheres are significantly harder than steel, ensuring excellent wear resistance.
✅ Superior Wear & Corrosion Resistance – Performs well in harsh environments, resisting abrasion, oxidation, and corrosion.
✅ High Compressive Strength – With a compressive strength of ~1800 MPa, these spheres can withstand heavy loads and high-impact applications.
✅ Good Toughness & Fracture Resistance – The 6% cobalt binder enhances toughness, reducing brittleness while maintaining extreme hardness.
✅ Precision Machining & Smooth Surface – Can be manufactured to high precision tolerances (±0.001mm) for specialized applications.

Common Applications:

🔩 Precision Bearings & Valve Balls – Used in high-performance bearings, check valves, and ballpoint pen tips due to extreme wear resistance.
