How strong is a smco samarium cobalt magnets?

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 magnet magnetism than neodymium iron boron weak, than ferrite strong, Sm2Co17 compressive strength 82Kg/mm2, SmCo5 compressive strength 102Kg/mm2. Sm2Co17 tensile strength 3.6Kg/mm2, SmCo5 tensile strength 4.1Kg/mm2.

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 Neodymium Iron Boron, you need a special permanent magnet meter - digital fluxmeter with Helmholtz coil to test.
