Core Product Advantages: Tailored to Your Needs

High-Performance Materials for Powerful Magnetism

Crafted from premium N52-grade neodymium iron boron, our magnets offer ultra-high remanence and energy product, ensuring stable, strong magnetic adsorption for secure wireless charging and efficient power transmission. Choose from N35-N55 grades to match diverse application scenarios.

Ring Structure: Ingenious Design

Our unique ring structure is tailor-made for wireless charger magnetic modules, enabling precise positioning and quick, accurate adsorption. Standard size: 54*4mm, with customizable thickness (2-15mm) to fit various wireless charging devices.

Diverse Surface Treatments for Versatility

Standard NiCuNi triple-layer plating offers excellent rust and corrosion resistance (salt spray test ≥72 hours). Optional treatments include epoxy encapsulation, rubber coating, gold/silver plating, zinc plating, etc., meeting special needs like waterproofing, scratch resistance, or decorative aesthetics.

Precision Magnetization Control for Stability

Support radial, axial, and thickness-direction magnetization with ≥95% flux uniformity, ensuring stable magnetic field distribution and preventing charging instability. Custom multi-pole magnetization (e.g., 4-pole, 8-pole) is available for complex magnetic circuit designs.

Wide Temperature Adaptability for Harsh Environments

Standard models resist up to 80℃, while special processes enable 230℃ heat resistance. Stable performance in extreme temperatures—ideal for vehicle-mounted high-heat scenarios or cold outdoor use.

Full-Process Quality Control: Peace of Mind

Rigorous Raw Material Inspection

All rare earth materials come from certified suppliers and undergo spectrometer testing for component accuracy, eliminating recycled materials at the source.

Intelligent Production Monitoring

AI visual inspection and advanced sensors monitor key parameters (dimensions, magnetic field distribution, coating adhesion) in real time, keeping defect rates below 0.2%.

Multiple Finished Product Tests

Products undergo rigorous checks: gauss meter magnetic testing, high-low temperature cycling, salt spray corrosion testing, drop tests, vibration tests, etc. Only certified products are delivered, accompanied by complete inspection reports.

FAQ

Q1: Can your ring-shaped neodymium magnets fit Magsafe wireless chargers from different brands?
A: Our ring magnets are designed with standardized precision (tolerance controlled at ±0.05mm), compatible with magnetic modules of mainstream Magsafe chargers on the market. For customization, simply provide your specific dimensions and magnetization direction requirements—our technical team will optimize the design to ensure perfect fit.

Q2: What is the temperature resistance of the product? Can it withstand high temperatures in vehicle-mounted environments?
A: Standard models resist up to 100℃, while special processes enable heat resistance up to 230℃. For vehicle applications, we’ve customized radially magnetized ring magnets with 150℃ resistance for North American clients, which passed strict high-low temperature cycling tests to ensure stable performance.

Q3: What is the minimum order quantity (MOQ)? How long does sampling and mass production take?
A: We support low MOQ sampling starting from 1 pieces, with a 2-day sample lead time. Mass production typically takes 3-5 days, ensuring quick response to your needs.

Q4: How do you ensure long-term stability of magnetic performance?
A: We implement full-process quality control: raw materials are tested for purity via spectrometers; magnetic field distribution is monitored in real-time during production; finished products undergo magnetic performance tests (using gauss meters and hysteresis loop testers) and reliability tests (drop, vibration, etc.). All products comply with ISO9001 and come with complete inspection reports.

Q5: Besides NiCuNi plating, what other surface treatment options are available?
A: In addition to standard NiCuNi triple-layer plating (salt spray test ≥72 hours), we offer epoxy encapsulation, rubber coating, gold plating, zinc plating, and more—tailored to waterproof, scratch-resistant, or anti-corrosion requirements for different scenarios.
