Rare earth magnets with large size or high magnetic energy products are known as super strong magnets or super powerful magnets. Large neodymium magnets are known worldwide people as super strong magnets.
Because the main component of a super neodymium magnet is iron, and iron is easy to oxidize, so the anti-corrosion ability of a super neodymium magnet is poor, and the surface must be coated before it can be used for a long time. Please refer to the table below to select the right coating of super magnet neodymium for your application.
Surface | Coating | Thickness (Microns) | Color | Resistance |
Passivation | 1 | Silver Grey | Temporary Protection | |
Nickel | Ni+Ni | 10-20 | Bright Silver | Excellent Against Humidity |
Ni+Cu+Ni | Good Against Salt Spray | |||
Zinc | Zn | 8-20 | Bright Blue | Excellent Against Salt Spray |
C-Zn | Shinny Color | Superior Against Humidity | ||
Tin | Ni+Cu+Sn | 15-20 | Silver | Superior Against Humidity |
Silver | Ni+Cu+Ag | 10-20 | Silver | Superior Against Humidity |

When handling Super Neodymium Magnets, exercise caution. Their intense magnetic force can cause injuries if mishandled. Avoid placing fingers between magnets or near metal objects, as sudden attraction can occur. Keep them away from electronic devices, credit cards, and pacemakers. To prevent accidents, use protective gear like gloves and eye protection. When separating magnets, slide them apart to avoid collision. Store them in a secure place, away from children and pets. If ingested, seek medical attention immediately. Adhere strictly to safety guidelines to harness the power of Super Neodymium Magnets without compromising personal well-being.
