China Neodymium And Ferrite Magnets Manufacturer & Supplier 
Samarium cobalt magnets, also introduced in previous issues, it is also a rare earth permanent magnets, magnetic properties than rare earth neodymium iron boron poor, but the maximum operating temperature up to 250-350 ℃, mainly used in high-end motors, military equipment and other fields, samarium cobalt magnets how strong? This question is often asked by many customers, today to tell you a brief introduction.
How strong is samarium cobalt magnet? First of all, let's compare it by 2 magnet samples;
Both specifications are 12*5mm, samarium cobalt suction force is around 5.4 pounds, NdFeB magnet is around 7.5 pounds.
5mm x 10mm specifications of the two magnets, samarium cobalt suction at about 4.5 pounds, NdFeB can also be up to 7 pounds.
Samarium cobalt magnets are not as magnetic as neodymium magnets, with a magnetic energy product of generally 20-32 MGOe. Samarium cobalt magnets of the same size have approximately 70-90% of the magnetic force of neodymium magnets, but they are more stable and resistant to high temperatures. Compared with ferrite magnets, the magnetic energy product is 4-6 times stronger.

Choose neodymium magnets or samarium cobalt?
It depends on one's own usage needs. Samarium cobalt is more suitable for working in high-temperature environments (>200 ℃). In more harsh environments, Samarium cobalt permanent magnets perform better than neodymium iron boron, which is suitable for use in better environments.
Ps: If you want to test the performance and magnetic properties of Samarium Cobalt and NdFeB, you need a special permanent magnet meter - digital fluxmeter with Helmholtz coil to test.
