Non-Magnetic WC-Ni Alloy Tungsten Carbide Sleeve with Precision Holes for MRI & Semiconductor Equipment

Non-Magnetic Tungsten Carbide Sleeve with Precision Holes

Engineered for Precision in Critical, Field-Sensitive Environments.

When your application demands absolute magnetic neutrality alongside complex internal features for lubrication, weight reduction, or sensor integration, standard components fall short. Our Non-Magnetic Tungsten Carbide Sleeve is the definitive solution. Fabricated from specialized WC-Ni alloy and machined with sub-micron precision, it delivers zero magnetic interference and long-lasting performance in the most demanding sectors like medical imaging and semiconductor manufacturing.

Core Technology & Material Advantage

At the heart of this sleeve is a proprietary WC-Ni (Tungsten Carbide-Nickel) alloy. By replacing the conventional cobalt (Co) binder with nickel (Ni), we eliminate ferromagnetism at its source while retaining the exceptional hardness and wear resistance tungsten carbide is known for.

• Guaranteed Non-Magnetic: Magnetic permeability (μ) is consistently < 1.002, making it perfectly safe and interference-free in MRI and other sensitive electromagnetic fields.

• Superior Material Properties:

  • Hardness: 90-92 HRA, ensuring exceptional resistance to wear and deformation.

  • Density: ~14.9 g/cm³, offering high rigidity and stability.

  • Corrosion Resistance: Excellent resistance to chemicals and coolants, ideal for cleanroom and medical environments.

• Functional Hole Designs:

  • Lubrication Holes: Ensure even oil film distribution for high-speed rotational or linear motion, drastically reducing wear.

  • Venting/Weight Reduction Holes: Optimize mass for dynamic balance in rotating assemblies without compromising structural integrity.

  • Mounting/Alignment Holes: Facilitate precise installation and integration within complex assemblies.

• Machining Excellence: We achieve remarkable precision in these internal features:

  • Positional Accuracy: Multi-hole pattern true position tolerance within ±0.01mm.

  • Diameter Consistency: Hole diameter tolerance as tight as ±0.005mm.

  • Surface Finish: Internal bore and holes can be finished to Ra 0.2μm for smooth fluid flow or reduced friction.

Standard Size Range (Fully Customizable):

• Inner Diameter (ID): Φ4mm to Φ80mm

• Outer Diameter (OD): Φ8mm to Φ100mm

• Length: 10mm to 150mm

• Hole Patterns: Designed to your specification (radial, axial, custom layouts).

Applications

This component is critical in industries where precision and non-magnetic properties are paramount:

• Medical & Life Sciences: MRI scanner components (RF coil mounts, gradient coil sleeves), non-magnetic bearings in surgical robots, and housings for diagnostic equipment.

• Semiconductor Manufacturing: Wafer handling robot arms, precision stages, and vacuum chamber fixtures requiring lubrication paths and absolute cleanliness.

• Advanced Research: Components within cryogenic systems, mass spectrometers, or particle accelerators where magnetic neutrality and custom venting are required.

• High-End Industrial: Specialized pumps, valves, or rotating machinery operating in corrosive or EMI-sensitive environments.
