When I don't say, do you know samarium cobalt is also a kind of rare earth magnet? It is favored by customers for its good magnetism and temperature resistance, and is divided into SmCo5 and Sm2Co17, of which Sm2Co17 is more common and widely used, why is this?
Here are some of the reasons why 2:17 type samarium cobalt magnets are more popular, read on and you will know the answer.
Sm2Co17 arc none coating magnets
1, Stronger magnetic energy
Sm2Co17 magnets can have a maximum magnetic energy product of 30 MGOe or even higher, while SmCo5 magnets usually have a maximum magnetic energy product of around 20 MGOe, which means that Sm2Co17 magnets can provide a much stronger magnetic field strength for the same volume.
2, Higher Temperature Resistance
Sm2Co17 magnets are able to maintain their magnetic properties at higher temperatures, the maximum operating temperature can reach 350 ℃, and the recently developed maximum operating temperature can reach about 500 ℃. The maximum working temperature of SmCo5 magnet is 250℃.
3, Better temperature stability
Sm2Co17 magnets show better stability of magnetic properties when the temperature changes, which means that their performance fluctuates less under different temperature conditions and is more stable and reliable.
4, Wider application
Due to its better overall performance, SM2Co17 is particularly suitable for aerospace, high-speed rotating machinery, precision instruments and other demanding applications.
Although Sm2Co17 has many advantages, it also has some shortcomings, such as it is more difficult to machine than SmCo5, due to the fact that Sm2Co17 is a harder material and is more prone to problems such as cracking when machining. In addition, SmCo5 magnets may be a better choice for applications that require specific shapes or fine machining due to its better machinability.
