Supplier's note

  1. Three Technical Breakthroughs:

    • N42M Grade: Outperforms standard N35 magnets by 20% in energy density.
    • Ni-Cu-Ni Coating: Reduces corrosion rates by 40% compared to single-layer coatings.
    • Precision Tolerance: ±0.05mm ensures seamless integration in tight motor tolerances.

  2. Optimal Version Selection:

    • Base Model: Ideal for standard industrial motors (e.g., HVAC systems) where cost efficiency is prioritized.
    • Advanced Model: Suited for harsh environments (e.g., chemical pumps) needing enhanced corrosion and heat resistance.
    • Pro Model: Designed for high-performance applications (e.g., aerospace actuators) requiring extreme durability and magnetic strength.

Example: The Pro Model’s 150°C tolerance enables safe operation in high-temperature furnaces, while its triple-layer coating prevents degradation in humid conditions. Pair this with its N50M grade to achieve 30% higher torque output in motors.
