NdFeB Magnet：From Mining to Manufacturing

Rare earth magnets break down into two categories: neodymium magnets and samarium-cobalt magnets. Both types have applications in numerous industries, including power generation, audio equipment, computer equipment, medical equipment, and more. You can even find rare earth magnets in electric motors and rare earth magnets on oil filters to help prevent engine wear. Before we discuss these magnets in more depth, let’s talk about some general characteristics of these two kinds of rare earth magnets.

As you can tell from the name of one of the magnets that we mentioned above, rare earth magnets aren’t entirely comprised of rare earth elements. For instance, samarium-cobalt magnets are comprised of (appropriately enough) both samarium and cobalt, while neodymium magnets contain substantial amounts of boron and iron in addition to its titular element.

Both types of magnet are extremely strong. However, neodymium boasts the strongest magnetic force. Samarium excels in its stability, resisting potentially damaging external factors such as extreme heat and corrosion.

Industry Applications

Rare earth magnets have appeared in the news in recent years due to several injuries attributed to magnet-powered toys. These magnets are powerful, and if accidentally ingested, they can lead to serious complications. But what are rare earth magnets used for other than children’s playthings? You might be surprised to learn that rare earth magnets play a major part in many industrial products and capital assets. These include:

• Magnetic bearings and couplings

• Lasers

• Automatic door locks

• Jet engines

• Smart bombs

• Welding clamps

• Electric-based musical instruments

• Stud finders for construction

• Audio speakers and headphones

• Missile guidance systems

• Information-technology storage

• Radar arrays

• Generators for wind power

• Electronic countermeasures

• Satellite communications

• Magnetic resonance imaging

• Roller coasters

• Motors and starters for electric vehicles

Neodymium Magnet

For most applications, neodymium magnets have become the default option. In addition to being more powerful than older types of rare earth magnets, they’re significantly cheaper and less brittle. They can also be molded into a wide variety of shapes, which is another factor that has boosted their popularity. However, some of the inherent characteristics of neodymium also limit the magnets’ end uses.
