Neodymium magnet, also known as NdFeB magnet, is a permanent magnet with Nd2Fe14B tetragonal crystal structure composed of an alloy of neodymium, iron and boron, and its main components are the rare earth elements neodymium (Nd), iron (Fe) and boron (B). Neodymium is part of this material, known as "rare earth." Rare earths get their name not because of their natural concentrations, but because of the difficulty in separating them from other materials that are linked by chemical bonds.

With nickel, zinc or copper coatings, neodymium magnets have excellent resistance to atmospheric media, and neodymium magnets are the strongest magnets on the market today, known as the king of magnets. They are highly magnetic with energy product (BH) max 10 times greater than that of ferrite magnets. NdFeB has excellent machinability and operating temperature up to 200°C. Also, neodymium magnets are widely used in various industries due to their stable performance and good cost performance.

What are the applications of neodymium magnets

In products that require strong magnets, neodymium magnets have replaced other types of magnets. The application scope of NdFeB magnets is as follows: 1. Electroacoustic field: speakers, receivers, microphones, sirens, stage audio, car audio, etc. 2. Electronic products: permanent magnet mechanism vacuum circuit breakers, magnetic latching relays, watt-hour meters, water meters, sound level meters, reed switches, sensors, etc. 3. Motor field: VCM, CDDVD-ROM, generator, motor, servo motor, micro motor, vibration motor, etc. 4. Mechanical equipment: magnetic separator, magnetic separator, magnetic crane, magnetic machinery, etc. 5. Medical and health care: nuclear magnetic resonance apparatus, medical equipment, magnetic therapy health care products, magnetized fuel saver, etc. 6. Other industries: anti-magnetization wax, pipe descaling agent, magnetic fixture, automatic mahjong machine, magnetic lock, door and window magnet, stationery magnet, luggage magnet, leather magnet, toy magnet, tool magnet, craft gift packaging, etc.

What makes neodymium magnets so unique?

NdFeB permanent magnets have the advantages of extremely high magnetic energy product and coercive force, and high energy density.

NdFeB magnets have strong magnetic force and are currently strong magnetic materials, they are widely used and cost-effective.

NdFeB magnets have good mechanical properties and can be easily processed into various shapes, including special-shaped magnets.

NdFeB magnets have high precision, and the tolerance can be controlled within ±0.02mm.
