Magnet Plating and Coating Options
- Oxidization (Rust) :NdFeB magnets will oxidize(rust) if left exposed. When a plating wears down or cracks, the exposed area will oxidize. An oxidized area will not result in complete degradation of the magnet, only the oxidized area will lose its strength. However the magnet will lose some structural integrity and become more susceptible to breakage.
- Durability: Depending on shape, permanent magnet substrate is brittle. A multilayered metal plating like nickel or zinc improves the magnets resistance to chipping and wear, particularly around corners.
- Harsh Environments:Platings vary in their tolerance of different harsh chemicals and abrasion. Salt and humidity in regions near the ocean are commonly overlooked when selecting a plating. Be sure to consider the magnets environment when selecting a plating.
Magnet Plating and Coating Options
A Magnetic field is an invisible flux moving from one end of the magnet to the other. Shown in Figure1. The flux consists of moving or spinning electrically charged particles invisible to the eye. If the max working temperature meet the requirement ,permanent magnets can retain the magnetic field for very long time even forever. Magnets have potential energy which means that they have the ability to conserve energy. The magnet will display or release some of its conserved energy when pulling towards or attaching to something then conserve or store the energy that the user exerts when pulling it off.
Every magnet has a north seeking and a south seeking face on opposite ends. The north face of one magnet will always be attracted towards the south face of another magnet.
Common Applications for Permanent Magnets
Neodymium magnets are strong magnets,frequently used for many types of sectors, commercial, industrial & technical applications where strong permanent magnets are required. Due to their high-magnetic strength, components that previously had to be large and heavy can now be miniaturized by using Neodymium magnet material.Common Applications: holding systems requiring very high holding forces, sensors, reed switches, hard disc drives, audio equipment, acoustic pick-ups, headphones & loudspeakers, MRI scanners, magnetically coupled pumps · motors & generators, magnetic tool holders, magnetic bearings, door catches, dental instruments, medical devices, magnetic separators, lifting machinery, crafts & model making, hanging artwork, levitation devices, POP displays, commercial signage, packaging closures, jewelry clasps & more.

Frequently Asked Questions
1. Q: What is the maximum operating temperature for Sintered NdFeB Magnets?
A: Sintered NdFeB magnets are known for their high performance, but they have specific temperature limitations. The maximum operating temperature for these magnets typically ranges from 80°C to 200°C, depending on the grade and formulation of the magnet. For example:
- Standard NdFeB magnets (e.g., N35, N38) are generally suitable for temperatures up to 80°C to 100°C.
- High-temperature grades (e.g., N35M, N38H) can operate at higher temperatures, with some grades like N35AH or N38UH capable of withstanding temperatures up to 200°C.
2. Q: How can I prevent demagnetization of Sintered NdFeB Magnets?
A: Demagnetization of Sintered NdFeB magnets can occur due to several factors, including high temperatures, external magnetic fields, and mechanical stress. Here are some tips to prevent demagnetization:
- Select the right grade: Choose a magnet grade suitable for your operating temperature and environment.
- Avoid high temperatures: Keep the magnets within their specified temperature range to prevent thermal demagnetization.
- Shielding: Use magnetic shielding materials to protect the magnets from strong external magnetic fields.
- Proper handling: Handle the magnets carefully to avoid mechanical stress, which can cause micro-cracks and affect magnetic performance.
- Storage: Store magnets in a cool, dry place, away from strong magnetic fields and corrosive environments.
3. Q: Are Sintered NdFeB Magnets susceptible to corrosion?
A: Yes, Sintered NdFeB magnets are susceptible to corrosion due to the presence of neodymium and iron in their composition. To prevent corrosion:
- Coating: Apply protective coatings such as nickel plating, zinc plating, or epoxy coating to protect the magnet from moisture and corrosive environments.
- Environment control: Store and use the magnets in dry environments to minimize exposure to humidity.
- Sealing: For applications in highly corrosive environments, consider sealing the magnets with additional protective layers or using corrosion-resistant materials in the surrounding structure.
- Standard NdFeB magnets (e.g., N35, N38) are generally suitable for temperatures up to 80°C to 100°C.
- High-temperature grades (e.g., N35M, N38H) can operate at higher temperatures, with some grades like N35AH or N38UH capable of withstanding temperatures up to 200°C.
4. Q: Can Sintered NdFeB Magnets be customized in terms of shape and size?
A: Yes, Sintered NdFeB magnets can be customized to meet specific application requirements. They can be produced in various shapes, including:
- Blocks
- Cylinders
- Rings
- Arcs
- Custom geometries
The customization process involves pressing the magnet powder into the desired shape and then sintering it. Custom sizes and dimensions can also be achieved through precision machining.
- Standard NdFeB magnets (e.g., N35, N38) are generally suitable for temperatures up to 80°C to 100°C.
- High-temperature grades (e.g., N35M, N38H) can operate at higher temperatures, with some grades like N35AH or N38UH capable of withstanding temperatures up to 200°C.
5. Q: How should I handle and store Sintered NdFeB Magnets to maintain their performance?
A: Proper handling and storage are crucial to maintaining the performance of Sintered NdFeB magnets:
- Handling:
- Use gloves: Wear gloves to prevent oils from your skin from transferring to the magnets, which can affect their surface and coating.
- Avoid dropping: Handle the magnets carefully to avoid mechanical stress and potential damage.
- Separate storage: Store magnets separately to prevent them from attracting each other, which can cause chipping or demagnetization.
- Storage:
- Dry environment: Store magnets in a cool, dry place to prevent corrosion.
- Away from magnetic fields: Keep magnets away from strong external magnetic fields to prevent demagnetization.
- Labeling: Clearly label the magnets with their grade, orientation, and other relevant information to avoid confusion.
- Standard NdFeB magnets (e.g., N35, N38) are generally suitable for temperatures up to 80°C to 100°C.
- High-temperature grades (e.g., N35M, N38H) can operate at higher temperatures, with some grades like N35AH or N38UH capable of withstanding temperatures up to 200°C.
