Magnetic Permeability <1.002 WC-Ni Series Non-magnetic Special Research Carbide Rotating Cylinder
The rotating column is precisely manufactured using WC-Ni non-magnetic cemented carbide. By replacing the traditional cobalt element with a nickel-based binder phase, the scientific solution completely solves the magnetic interference problem of ordinary cemented carbide. In magnetic field-sensitive environments such as MRI medical equipment, semiconductor manufacturing, and scientific research instruments, it achieves high precision, no magnetic interference, and high stability.
Introduction to the main grades of non-magnetic tungsten carbide
| Grade/System | Main Components | Hardness (HRA) | Flexural Strength (MPa) | Characteristics and Applications |
| M10 Non-Magnetic Tungsten Carbide | WC-Ni System | 92.5 | 3240 | General-purpose non-magnetic molds, corrosion-resistant tools |
| WC-Ni System | WC-0.75Al-14.25Ni | 87.4 | 1670 | Non-strongly magnetic at room temperature, relatively high magnetic permeability |
| WC-Cr₃C₂-Ni System | WC-Cr₃C₂-Ni | - | - | Commonly used in industry, with 1-3% Cr₃C₂ addition |
| WC-Cr₃C₂-Mo-Ni System | WC-Cr₃C₂-Mo-Ni | - | - | Adds Mo to improve magnetic properties |
| MAST-N20 | WC-Ni (Japan) | 91.0 | 3300 | Highly corrosion-resistant, suitable for nozzles, seals, and molding dies |
Grade Selection Tips: The above grades primarily achieve non-magnetic properties by using nickel (Ni) as a binder phase. Different grades have different composition and performance emphases. When selecting, please consider your specific magnetic permeability requirements, hardness, strength, and corrosion resistance.
Core Technologies:
1. Non-magnetic Material Design
A nickel-based binder phase is used to ensure non-magnetic properties from the source.
Strict composition control prevents the introduction of magnetic impurities.
2. Precision Manufacturing and Processing
Specialized grinding technology tailored to the characteristics of non-magnetic materials.
Ensuring the dimensional accuracy (±0.002mm) and dynamic balance grade (G1.0) of the rotating column.
3. Strict Quality Inspection
100% magnetic permeability testing ensures that every product meets non-magnetic standards.
Industrial CT non-destructive testing ensures internal quality assurance.
Typical Application Scenarios:
Medical imaging equipment: Rotating components in MRI scanners, such as those used in magnetic resonance imaging (MRI), prevent interference with imaging.
Semiconductor manufacturing: High-precision equipment such as wafer transfer robots and photolithography machines, prevent magnetic fields from affecting microelectronic components.
Scientific research equipment: Electron microscopes, high-energy physics experimental equipment, etc., ensure measurement accuracy.
Aerospace: Satellite attitude control components and aviation instruments, etc., meet the requirements of special environments for non-magnetic environments.
