Gold-Plated Neodymium Magnets – High-Conductivity Rare Earth Magnets for Electronics, Medical & Aerospace Applications
- Medical Devices: Where biocompatibility and corrosion resistance are critical for patient safety
- Aerospace: For lightweight, high-performance components that withstand extreme environments
- High-End Electronics: In precision sensors, connectors and RF devices that require superior conductivity
⭐ Key Features
🔹 1. Ultra-Thin Gold Coating for Superior Performance
- Precision Gold Layer: 0.5-2μm thickness, applied with advanced electroplating technology for uniform coverage even on complex shapes
- No Magnetic Strength Loss: The ultra-thin gold layer has zero impact on magnetic flux, ensuring full neodymium grade performance (N35-N52)
- Dual-Layer Benefit: Gold coating provides both superior electrical conductivity and extreme corrosion resistance — a rare combination in magnet coatings
🔹 2. High Electrical Conductivity (Critical for Electronics & Sensors)
- Gold’s Natural Advantage: Gold is one of the most conductive metals, with excellent electrical resistance stability over time
- Low Contact Resistance: Ideal for use in electrical connectors, switches and precision sensors where consistent electrical performance is essential
- RF Compatibility: Gold plating minimizes signal loss in high-frequency applications, making these magnets perfect for RF devices and communication equipment
🔹 3. Extreme Corrosion Resistance & Longevity
- Triple-Layer Protection: NiCuNi base plating + copper layer + gold top layer = unmatched corrosion resistance
- Passes 2000+ Hour Salt Spray Test: Outperforms standard NiCuNi and epoxy coatings in harsh chemical and humid environments
- No Tarnishing: Gold coating resists tarnishing and oxidation, ensuring long-term performance in critical applications
🔹 4. Biocompatibility (Medical Device Grade)
- ISO 10993 Certified: Our gold-plated magnets meet biocompatibility standards for use in medical devices
- Non-Toxic & Non-Reactive: Gold is biologically inert, making these magnets safe for use in implantable devices, diagnostic equipment and surgical tools
- Sterilization Compatible: Withstands autoclave, gamma radiation and ethylene oxide (EtO) sterilization processes without degradation
🔹 5. Full Grade & Customization Options
- Magnetic Grades: N35, N42, N45, N50, N52 (choose the exact strength for your application)
- Standard Sizes: Discs (Φ2mm-Φ50mm), blocks (5×5×2mm to 50×50×20mm), rings (custom inner/outer diameters)
- Custom Shapes: Precision-machined custom shapes, chamfered edges, countersunk holes — all with uniform gold plating
- Low MOQ for Custom Orders: We support small-batch customizations for specialized applications
