SmCo - Model Sm2Co17 -High Performance Magnet
Sm2Co17-based magnets are still playing an irreplaceable role in the permanent magnet industry due to its unique high temperature magnetic properties and superior magnetic stability, then it always serving to the high-speed motors, electronic communication, and aerospace. High energy product magnets are the important basis to accelerate miniaturization and high efficiency of the device. Thus, obtain high performance SmCo magnet has always been a goal since the advent of Sm2Co17.
Although the remanence and magnetic energy product of high-performance samarium cobalt (XGS33H and XGS35H) are lower than the N42EH and N38AH grades of neodymium iron boron at lower temperatures, their remanence and magnetic energy product are significantly higher at higher temperatures than the N42EH and N38AH grades of neodymium iron boron. With the increase of temperature, the remanence and magnetic energy product of N42EH and N38AH grades of neodymium iron boron deteriorate rapidly, especially the coercivity. However, high-performance samarium cobalt still retains high magnetic properties and exhibits excellent thermal stability.
High Performance Samarium Cobalt Magnet
High magnetic energy product, high remanence, and high coercive force are commonly used in various fields such as high-speed motors, traction motors, and magnetic couplers. Excellent thermal stability and high magnetic retention at high temperatures.
High temperature resistant magnet
The use temperature of the magnet is greater than 550?, which is much higher than the use temperature of ordinary samarium cobalt magnets (350?). Generally, the coercivity of samarium cobalt at 550? is 2 kOe. Our high-temperature resistant magnets still have a coercive force of 6.51 kOe at 550?, with a magnetic loss of less than 5%.
Low temperature coefficient magnet
Within a certain temperature range, remanence basically does not change with temperature. We produce zero temperature coefficient magnets (remanence temperature coefficient is less than 0.05%) and positive temperature coefficient magnets (remanence temperature coefficient is positive).
Low temperature coefficient magnets are commonly used in various precision instruments, gyroscopes, autonomous driving, and other fields.
