Supplier's note

  1. Three Breakthroughs:

    • N52 Grade: 50% stronger than industry-standard N35 magnets, enabling use in heavy machinery.
    • Gold Coating: Triple corrosion resistance compared to uncoated magnets, ideal for marine or chemical environments.
    • ±2% Tolerance: Precision 3x tighter than standard magnets, critical for aerospace or medical equipment.

  2. Version Selection Guide:

    • Base Model: Suitable for general industrial use (e.g., securing panels in HVAC systems).
    • Advanced Model: Preferred for corrosive environments (e.g., marine electronics with NiCuNi coating).
    • Pro Model: Optimal for high-strength applications (e.g., robotics grippers requiring N52’s triple-certified durability).

*Example benefit: The Pro version’s N52 grade, combined with gold coating, ensures safe handling of corrosive fluids while maintaining magnetic performance in automotive manufacturing.
