Non-magnetic Tungsten Carbide Core Ring with Magnetic Permeability <1.002 and Residual Magnetization <0.05 mT Made from 100% Virgin Material

μ-grade non-magnetic tungsten carbide core ring with a magnetic permeability of <1.002 · Special anti-interference material for precision instruments

When precision measurement encounters magnetic field interference—
This non-magnetic core ring, precision-manufactured using nickel-bonded tungsten carbide (WC-Ni), undergoes a special demagnetization process to completely eliminate the magnetic interference issues associated with traditional tungsten steel parts. This ensures zero magnetic interference, high precision, and long-life stable operation in magnetic field-sensitive environments such as MRI medical equipment and semiconductor manufacturing.

Non-Magnetic Principle: A Breakthrough in Materials Science
▸ Non-Magnetic Mechanism:
- Nickel-based binder phase replaces the traditional cobalt phase
