Ferrite Permanent Magnet/Alnico/SmCo

SAMARIUM COBALT

The Samarium-Cobalt magnets, introduced in the early 1960s, are rare earth magnets with distinct technical characteristics that make them quite sought after and suitable for specific scientific fields.
They are distinguished in two macro-categories, differentiated according to the ratio of Samarium and Cobalt present in the alloy: SmCo5 and Sm2Co17.

Similar to neodymium magnets, they are produced through a sintering process, but with additional steps. They share a high performance in terms of attraction and coercivity with Neodymium magnets, while improving some key features: They have a maximum operating temperature of 350 °C and greater magnetic field stability from this threshold and down to -150 °C. In addition, their chemical composition makes them completely (or almost, in the case of Sm2Co17) immune from oxidation by external agents, so much that they do not require any kind of surface coating.
We can also supply the magnets with nickel coating on request.

Their technical characteristics make them the best choice for many applications in specific technical fields, such as laboratory measuring instruments, industrial turbochargers, cryogenic systems, acoustic equipment, etc.

The force values given in the tables are the result of dynamometric tests performed with a 10 mm thick iron plate.
Any variations from this standard in the use may change the actual performance of the magnet.

It is always recommended to perform specific tests according to your application.
