Tungsten Carbide Studs Pin with High Hardness


Tungsten carbide pin (the typo is common). It’s a precision cylindrical component made from tungsten carbide (WC, usually with cobalt binder, e.g., WC-92% + Co-8%), produced via powder pressing, high-temperature sintering, and precision grinding to ultra-tight tolerances (often ±0.002–0.005 mm). It’s valued for extreme hardness (~89+ HRA, Mohs 8.5–9), wear resistance, high rigidity, and dimensional stability even under heat/abrasion, far outperforming steel pins.
