Additionally, special-shaped neodymium magnets can be created to meet unique requirements, such as irregular geometries or complex designs.
What Grades of Neodymium Magnets Are Available?
NdFeB magnets are graded based on their magnetic strength and temperature resistance. Common grades include:
- N35 to N52: Higher numbers indicate stronger magnetic fields.
- H, SH, UH, EH: These grades signify the magnet’s ability to withstand high temperatures.
Choosing the right grade ensures that the magnet performs optimally in its intended environment. For example, N52 magnets are among the strongest available, while SH magnets are designed for high-temperature applications.
What Coating Options Are Available?
To protect against corrosion and wear, neodymium magnets can be coated with various materials, including:
- Nickel: The most common coating, providing a smooth and durable finish.
- Epoxy: Ideal for harsh environments where additional protection is needed.
- Gold or Silver: Often used for medical or decorative purposes.
These coatings enhance the magnets’ longevity and ensure consistent performance over time.
Applications of Custom Neodymium Magnets
Where Are Custom Neodymium Magnets Used?
Neodymium magnets are used in various industries due to their strength and versatility. Common applications include:
