Product Description

What are NdFeB magnets?

NdFeB magnets, also known as NdFeB permanent magnets, are a rare earth permanent magnetic material composed of neodymium (Nd), iron (Fe) and boron (B). Its chemical formula is usually expressed as Nd2Fe14B. NdFeB magnets are one of the strongest commercial permanent magnetic materials known to date.
High magnetic energy product

NdFeB magnets have a very high magnetic energy product (BHmax), providing strong magnetism in a compact volume.

High coercivity

High resistance to demagnetization when faced with external magnetic fields or physical shocks.

Shape & Coating

Available in various shapes (round, square, rod) with protective coatings like nickel, zinc, or gold for corrosion resistance.

Frequently Asked Questions

What makes NdFeB magnets so strong?
NdFeB magnets have a very high magnetic energy product (BHmax), which allows them to generate powerful magnetic fields even with small physical dimensions.
Do NdFeB magnets require surface treatment?
Yes, because they contain iron which is prone to oxidation. Common coatings include Nickel (Ni-Cu-Ni), Zinc, or Gold to improve corrosion resistance.
What is the maximum operating temperature?
Standard grades typically have an operating temperature of 80°C. However, special high-temperature grades can be produced for specific industrial needs.
What shapes can Neodymium magnets be made into?
They are highly versatile and can be processed into blocks, discs, rings, countersunk holes, rods, and complex custom geometries based on technical drawings.
Are these magnets suitable for outdoor use?
With proper plating (like Epoxy or thick Nickel), they can be used in various environments, though direct long-term exposure to harsh moisture should be managed with appropriate protection.
Which industries benefit most from NdFeB magnets?
Key industries include electric vehicle motor manufacturing, wind power generation, consumer electronics (speakers/hard drives), and medical imaging (MRI).
