Difference Between NdFeB Magnet and SmCo Magnet
Hello, friend, welcome to HSMAG magnet website. This article introduces the difference between rare earth neodymium magnet(NdFeB) and rare earth samarium cobalt magnet (SmCo) . Let’s learn about it with the editor.
The remanence of NdFeB is higher than that of SmCo. At present, it can reach about 55, and SmCo can only reach 32. Remanence, can be simply understood as the suction as the saying goes, NdFeB is much larger, but the coercive force of NdFeB is lower than SmCo. Coercive force is the ability to resist demagnetization.

The high temperature resistance of NdFeB is not very good. At present, the maximum working temperature is about 200 ℃, Samarium cobalt,, can withstand 300 degrees. Some special products can achieve 450 degrees after reducing remanence. That is to say, remanence is related to coercive force (suction and anti demagnetization ability).

|Average torque at
|Average torque at 180°C||1.86Nm||1.99Nm|
In terms of price, Neodymium iron boron is cheaper than samarium cobalt. At present, most of the market uses more neodymium iron boron.
The above is about the difference between NdFeB and SmCo. HSMAG hope it can help you!
