What are the advantages of samarium cobalt magnets?

Samarium cobalt magnets have many advantages that make them ideal for industrial applications. These advantages have contributed to the growing popularity of samarium cobalt magnets. In fact, samarium cobalt magnets may in some cases be more suitable than neodymium magnets.

The advantages of samarium cobalt magnets: high heat resistance (up to 300°C), low temperature resistance (below absolute zero, -273°C), price sensitive for the market, high corrosion resistance, high demagnetization resistance, high magnetic force strength.

While samarium cobalt magnets offer several advantages, there are some considerations to consider when considering samarium cobalt magnets for your business application. SmCo magnets can be brittle and work best in applications that do not require direct impact. These magnets are sensitive to the market price, but are usually more expensive than some neodymium magnets. This is mainly due to the production costs for cobalt and the fact that most magnets are produced abroad.

What is the material difference between samarium cobalt magnets and neodymium iron boron magnets?

Composition of the samarium cobalt magnet:

Samarium cobalt magnet is a magnetic material made of samarium, cobalt and other rare earth metals by proportioning, melting into alloys, crushing, pressing and sintering. Rare earth metal samarium, rare earth metal cobalt, metal element iron, metal element copper and a small amount of zirconium added.

Composition of the NdFeB magnet:

NdFeB magnets are tetragonal crystals of neodymium, iron and boron (Nd2Fe14B). Rare earth metal neodymium, metallic element iron, non-metallic element boron, a small amount of dysprosium, niobium and aluminum are added.

What are the performance characteristics of samarium cobalt magnets?

Samarium cobalt magnets have a high magnetic energy product, low temperature coefficient, high working temperature of up to 350°C and no negative temperature limit. If the working temperature is above 180°C, its larger magnetic energy product, temperature stability and chemical stability are higher than neodymium. Iron boron permanent magnet material. The sintered NdFeB permanent magnet material has strong magnetic properties.

What are the applications of samarium cobalt magnets?

Due to the superior properties of samarium cobalt magnets, these magnets have a wide range of industrial applications. SmCo magnets are widely used in applications where magnetic strength and stability at high temperatures are critical. Some examples of industrial applications of samarium cobalt magnets are:

Electric motors and motors, sensors, pump couplings, high temperature applications, food processing, prosthetics, generators, etc.
