Tungsten Carbide Studs Pin with High Hardness

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.

Tungsten Carbide Pin Key Production & Properties

Material composition: WC as the hard phase, Co as the binder phase (common grades YG6, YG8, YL10.2). Sintered at ~1400°C to form a dense, homogeneous structure.
Critical properties: Density ~13–15 g/cm³, excellent corrosion resistance (in most industrial media), low thermal expansion, high compressive strength.
Tolerances & finish: Surface finish down to Ra 0.025 μm; used for gauging, alignment, and mold cores that demand lifelong precision.

Tungsten Carbide Pin Common Types & Applications

Alignment pins: For fixtures, aerospace/mold assemblies; maintain position after thousands of cycles.
Core pins (injection mold): Form internal cavities in plastic/metal parts (medical syringes, electrical connectors); reduce deflection in high-cavitation molds.
Taper pins: Tapered cylinders for heavy machinery joints (gears, mining equipment).
Gauge pins: For measuring hole diameters/spacings in precision engineering.
Tire studs, agitator pins, micro-drill pins, and wear pins in automotive, mining, electronics, and medical sectors.
