Key Features:
– Ultra-High Hardness: Composed of tungsten carbide with a cobalt binder (6%–12% Co), these balls achieve a Vickers hardness of up to 1600–1800 HV, ensuring resistance to abrasion, deformation, and mechanical wear.
– Corrosion & Chemical Resistance: Withstands aggressive environments, including acidic, alkaline, and high-salinity conditions, making them suitable for petrochemical and marine applications.
– High-Temperature Stability: Maintains structural integrity and dimensional accuracy at temperatures up to 600°C, ideal for high-heat processes such as steam valves or refinery systems.
– Precision Engineering: Tight sphericity tolerance (±0.005mm) and surface finish (Ra ≤ 0.2μm) ensure leak-proof sealing and smooth operation in valve assemblies.
– Long Service Life: Outperforms traditional steel or ceramic balls, reducing downtime and replacement frequency in demanding industrial settings.

Applications:
– Oil & Gas: Used in ball valves, choke valves, and downhole tools for drilling, extraction, and pipeline systems.
– Chemical Processing: Ideal for controlling corrosive fluids in reactors, pumps, and metering systems.
– Power Generation: Employed in steam turbine valves and high-pressure hydraulic systems.
– Aerospace & Automotive: Critical for fuel injection systems, hydraulic controls, and precision fluid handling.

Advantages:
– Cost Efficiency: Extended lifespan reduces maintenance costs and operational interruptions.
– Versatility: Compatible with a wide range of media, including abrasive slurries, hydrocarbons, and high-purity chemicals.
– Customization: Available in diameters from 1mm to 50mm, with options for tailored cobalt content, surface coatings (e.g., TiN, AlCrN), or specialized geometries.
– Sustainability: Durable design minimizes material waste and supports eco-friendly industrial practices.

Technical Specifications:
– Material: Tungsten Carbide (WC) with Cobalt (Co) binder (6%–12% Co).
– Hardness: HRA 89–94 (equivalent to HRC 70+).
– Temperature Resistance: Up to 600°C.
– Standards Compliance: ISO 9001-certified manufacturing with full traceability.
