Tips:

1. These magnets are brittle. Please handle with care and avoid direct impact or collision, as they may crack or break.

2. Keep magnets away from children to prevent accidental swallowing or injury.

 

⭐ Advantages of Material : This N52 black epoxy coated round magnet is made from the strongest NdFeB material available on the market, offering exceptional magnetic force despite its compact size.

NdFeB vs Ferrite:

1. For the same size, NdFeB magnets are 4-10 times stronger than ferrite magnets.

2. Higher energy density → smaller, lighter, stronger.

3. Ferrite magnets are affordable but not suitable for high-intensity applications.

 

⭐ Advantages of Coating : This strong black disc neodymium magnet features a premium epoxy coating, offering superior surface protection and durability compared to common nickel or zinc coatings.

1. A four-layer epoxy coating system ensures excellent corrosion resistance and moisture resistance.

2. Effectively protects the surface from scratches and dents, allowing safe contact with fragile metals.

3. Stronger chemical and salt spray resistance compared to nickel or zinc coatings.
