Introduction of Samarium Cobalt Micro Magnet;
Samarium-cobalt magnets are also called samarium magnets by many customers. They are divided into sintering and bonding. Our company only supplies sintered samarium-cobalt magnets. The grades are SmCo5 and Sm2Co17. The magnetic properties are weaker than neodymium iron boron magnets, stronger than ferrite and alnico magnets. It is the most expensive of these four types of magnets. The magnetic properties are very stable, with strong corrosion and oxidation resistance.
Use of samarium cobalt micro magnets;
Micro magnets are commonly used in watches, sensors, medical equipment, telecommunications equipment, micro-electromechanical systems (MEMS) and many other applications. The most representative of these applications are watch movement rotor magnets and opto-isolator magnets.
How small the size of the samarium cobalt miniature magnet can be;
Like neodymium iron boron, samarium cobalt magnets can also be made into tiny specifications of about 1mm.
If you need to buy samarium cobalt （micro）mini magnets, please contact us. We are located in Dongguan, China.
