Product Description
Groove Accuracy ±0.003mm Non-magnetic Alloy Semiconductor And Medical Equipment Dedicated Drive Shaft
The grooved shaft is precision-manufactured from WC-Ni non-magnetic cemented carbide. By replacing cobalt with a nickel-based binder phase and utilizing nano-scale groove processing technology, it simultaneously addresses the magnetic interference and positioning accuracy issues of traditional drive shafts. This enables superior transmission performance with zero magnetic interference, precise positioning, and long-term stability in magnetic field-sensitive environments such as semiconductor equipment and medical instruments.
Material Science
- Matrix Composition: 90% WC + 10% Ni, a special non-magnetic formula
- Magnetic Properties: Permeability <1.002, Residual Magnetization <0.05 mT
- Physical Properties:
- Hardness: 92 HRA (Vickers Hardness 1800 HV)
- Density: 14.8-15.1 g/cm³
- Coefficient of Thermal Expansion: 5.2*10⁻⁶/K
- Non-magnetic Principle: A nickel binder phase replaces the traditional cobalt phase, fundamentally eliminating ferromagnetism
