Neodymium (NdFeB) Rare Earth High Energy Performance Magnets

Ready to buy? Visit our magnet store

Neodymium Iron Boron (NdFeB) magnets are the strongest commercially available permanent magnets. They provide significantly higher magnetic strength than ceramic and alnico materials, making them ideal for applications where maximum holding force is required in a compact size.

NdFeB magnets are more sensitive to temperature than other magnetic materials. Elevated temperatures can result in temporary or permanent loss of magnetic strength. Standard maximum operating temperature is 176°F (80°C), with higher temperature grades available upon request.

Available in common grades including N35, N42, N52 and more.

Frequently Asked Questions

What makes neodymium magnets stronger than ceramic magnets?
Neodymium (NdFeB) magnets have a much higher energy product, allowing them to generate significantly more magnetic force in a smaller size compared to ceramic magnets.

What temperature can neodymium magnets operate at?
Standard neodymium magnets have a maximum operating temperature of 176°F (80°C). Higher temperature grades are available for more demanding applications.

Do neodymium magnets lose strength over time?
Neodymium magnets have excellent long-term stability. When used within their operating limits, they retain their magnetic strength for many years with minimal loss.

Do neodymium magnets require coatings?
Yes. Neodymium magnets are susceptible to corrosion, so they are typically plated or coated with materials such as nickel, zinc, or epoxy for protection.

Can neodymium magnets be machined or drilled?
No. Neodymium magnets are hard and brittle and cannot be machined with conventional tooling. They must be manufactured to size or ground using specialized processes.

Are custom sizes and shapes available?
Yes. Neodymium magnets can be produced in a wide range of shapes, sizes, grades, and coatings to meet specific application requirements.

How do I choose the right magnet grade?
Selection depends on required holding force, operating temperature, and environment. Higher grades provide more strength but may have lower temperature limits.
