Product Description
Precision Non-Magnetic Alloy Mold Components for Advanced Manufacturing
Engineered for Magnetic-Sensitive Molding Environments
In precision injection molding, die casting, and powder compaction—particularly when processing magnetic materials or manufacturing components for sensitive equipment—standard tool steel molds introduce critical risks. Magnetic interference can compromise part quality, while insufficient wear resistance leads to premature tool failure.
Superior Wear Resistance & Tool Life
| Property | Non-Magnetic Carbide (WC-Ni) | Non-Magnetic Steel (e.g., AISI 316) | Standard Tool Steel |
|---|---|---|---|
| Hardness | HRA 87 - 92 (HV 900-1700) | HRC 20-25 | HRC 50-58 |
| Wear Life | 10-50x longer | 1x baseline | 5-10x baseline |
| Compressive Strength | > 4000 MPa | ~200 MPa | ~2000 MPa |
| Magnetic Permeability | < 1.002 | 1.02-1.05 | > 100 |
Corrosion & Chemical Resistance
Nickel-bonded carbides offer significantly better corrosion resistance than cobalt-bonded grades, making them ideal for:
- Molding corrosive materials (PVC, fluoropolymers, engineering plastics with flame retardants)
- Operating in humid or chemically aggressive environments
- Applications requiring frequent cleaning or sterilization
Thermal Stability & Conductivity
WC-Ni alloys maintain dimensional stability across wide temperature ranges with:
- Low thermal expansion coefficient: ~5.5 × 10⁻⁶ /K
- Good thermal conductivity: Helps dissipate heat in high-cycle molding
Key Applications & Industries
| Industry | Application | Why Non-Magnetic Alloy Components |
|---|---|---|
| Magnetic Material Molding | Ferrite cores, bonded magnets, magnetic polymer components | Prevents magnetization of molded parts; eliminates magnetic attraction of powders during filling |
| Medical Device Manufacturing | Implantable components, surgical instrument handles, diagnostic consumables | Zero magnetic contamination, corrosion resistance for sterilization, biocompatibility |
| Semiconductor & Electronics | Connector housings, sensor components, micro-switch parts | No electromagnetic interference, wear resistance for glass-filled materials |
| Precision Optics | Lens holders, light guides, optical mounts | Mirror-finish capability (Ra < 0.1μm) prevents surface defects |
| Powder Injection Molding (MIM/CIM) | Metal and ceramic micro-components | Exceptional wear resistance for abrasive feedstocks |
| Aerospace & Defense | Structural components, EMI-sensitive housings | Non-magnetic signature, dimensional stability under extreme conditions |
Material Selection Guide
| Material | Hardness | Magnetic Permeability | Key Characteristics | Best Applications |
|---|---|---|---|---|
| WC-Ni (Standard) | HRA 90-91 | < 1.002 | Balanced wear resistance and toughness | General non-magnetic tooling |
| WC-Ni-Cr | HRA 89-90 | < 1.002 | Excellent corrosion resistance | Medical, chemical environments |
| WC-Ni Nanocomposite | HRA 92+ | < 1.002 | Ultra-high wear resistance | High-volume, abrasive materials |
| Non-Magnetic Steel | HRC 20-45 | 1.02-1.05 | Machinability, lower cost | Prototypes, low-wear applications |
| Non-Magnetic Tool Steel | HRC 45-55 | 1.005-1.01 | Higher strength than stainless | Structural mold components |
