Product Description

WC-Ni Alloy Precision Rotor & Bearing Component Center Core
Our Non-Magnetic Tungsten Carbide Center Shafts and Core Components (often referred to as "lower center cores" or mandrels in assemblies) are engineered to be the perfect, inert heart of your device. Manufactured from specialty WC-Ni (Tungsten Carbide-Nickel) alloy, they provide the ultimate combination of absolute magnetic neutrality, extreme hardness, and outstanding dimensional stability where it matters most.
Core Benefits
  • Guaranteed Zero Magnetic Interference: The nickel-based binder system ensures a magnetic permeability (µ) of < 1.002, making these shafts and cores completely safe for use in MRI systems, semiconductor equipment, and advanced laboratory instrumentation without risking data corruption or field distortion.
  • Unmatched Wear Resistance & Longevity: With a typical hardness of 90-93 HRA, our carbide cores resist abrasion and deformation far better than steel. This translates to longer service life, maintained precision over time, and reduced maintenance downtime for critical machinery.
  • Superior Rigidity and Stability: The high density (~14.8-15.0 g/cm³) and low thermal expansion coefficient of tungsten carbide ensure the shaft maintains its precise shape and tolerances under operational stress, centrifugal forces, and temperature variations, leading to smoother operation and higher final product accuracy.
  • Corrosion & Chemical Resistance: Ideal for demanding environments, these components resist degradation from coolants, lubricants, and other mild chemicals, ensuring reliability.
