Supplier's note

1. Three Technical Breakthroughs:

   • High-Grade N52 Neodymium: The Pro Model’s N52 grade delivers 50% stronger magnetic force than the Base Model, enabling compact yet powerful motor designs.
   • Precision Tolerance: ±0.05mm accuracy ensures seamless integration into precision machinery.
   • Ni-Cu-Ni Coating: Reduces corrosion risk by 40% compared to standard coatings, extending lifespan in industrial settings.

2. Optimal Version Selection:

   • Base Model (N35): Ideal for standard motors or low-strength applications where cost efficiency is prioritized.
   • Advanced Model (N42): Best for industrial machinery requiring balanced performance and durability, such as pumps or sensors.
   • Pro Model (N52): Suited for high-performance applications like electric vehicle motors or robotics, where compact size and extreme strength are critical.

With the Pro Model’s N52 grade, you can achieve 50% stronger magnetic fields than traditional N35 magnets, enabling smaller motor designs without sacrificing power. Pair its premium coating with high-temperature stability to ensure reliability in harsh environments.
