Cemented Carbide Pierced Balls

Cemented Carbide Pierced Balls are specialized spherical components precision-engineered from tungsten carbide (WC-Co) with through-holes or perforations, designed to meet the rigorous demands of fluid control, filtration, and high-wear applications. Combining the unmatched hardness and corrosion resistance of cemented carbide with innovative hollow geometries, these balls deliver superior performance in environments requiring precise flow regulation, abrasive media handling, or complex mechanical integration.

Key Features:
– Advanced Hollow Design: Precision-drilled holes (standard or custom diameters from 0.2mm to 10mm) enable fluid passage, gas distribution, or mounting compatibility without compromising structural integrity.
– Ultra-High Wear Resistance: Tungsten carbide-cobalt matrix (6%–12% Co) ensures Vickers hardness up to 1800 HV, ideal for abrasive slurries, high-pressure systems, or particle-laden flows.
– Corrosion & Thermal Stability: Resists acids, alkalis, and oxidation at temperatures up to 600°C, suitable for harsh chemical, oil and gas, or high-heat industrial processes.
– Dimensional Precision: Tight tolerances on hole placement (±0.01mm) and sphericity (≤0.005mm) ensure consistent performance in dynamic assemblies.
– Lightweight Durability: Hollow structure reduces weight while maintaining strength, critical for rotating components or high-speed systems.

Applications:
– Fluid Control Systems: Used in precision valves, nozzles, and flow regulators for oil and gas, chemical processing, or water treatment.
– Filtration & Separation: Acts as wear-resistant filter media or grinding beads in mining, pharmaceuticals, or food processing equipment.
– Spray Technology: Integral to atomizers, fuel injectors, or coating systems requiring precise fluid dispersion.
– Mechanical Assemblies: Facilitates mounting in bearings, sensors, or robotic joints with integrated fluid/pneumatic channels.
– Aerospace & Defense: Deployed in hydraulic systems, missile guidance mechanisms, or fuel delivery units demanding reliability under extreme conditions.

Advantages:
– Enhanced Functionality: Combines fluid dynamics optimization with material robustness for multi-purpose industrial solutions.
– Longevity: Outperforms stainless steel or ceramic pierced balls in abrasive or corrosive environments, reducing replacement costs.
– Custom Geometry: Choose hole patterns (single/multiple holes, radial/axial alignment), surface finishes (Ra ≤ 0.4μm), or coatings (e.g., DLC, TiN) for specific operational needs.
– Energy Efficiency: Lightweight design lowers inertial loads in rotating systems, improving energy consumption in pumps or turbines.

Technical Specifications:
– Material: Tungsten Carbide (WC) with Cobalt binder (6%–12% Co).
– Hardness: 1500–1800 HV (HRA 89–94).
– Hole Diameter Range: 0.2mm–10mm (customizable).
– Temperature Resistance: -200°C to +600°C.
– Pressure Tolerance: Up to 1000 bar (dependent on wall thickness and design).
– Certifications: ISO 9001-compliant manufacturing with full material traceability.
