Application of SmCo Magnets 20150919

Magnet Manufacturer China Rare Earth Magnet Limited

Samarium-cobalt magnet is also called SmCo magnet, SmCo permanent magnet, rare earth cobalt permanent magnet and so on. It is mixed by ratio with Sm, and cobalt and other rare earth metal material, smelted into alloy, and then be crushed, compressed and sintered into shapes. SmCo magnets has high magnetic energy product, and very low temperature coefficient; its highest operating temperature can be up to 350 ℃, negative temperature unlimited. When the operating temperature reaches 180 ℃, its maximum magnetic energy product, the temperature and chemical stability can exceed neodymium magnets.

SmCo magnet has excellent resistance to corrosion and oxidation; so are widely used in aerospace, defense industry, microwave devices, telecommunications, medical equipment, instruments, apparatus, magnetic actuators, sensors, magnetic processor, motors, magnetic cranes, and so on.

Helpful hints
(1) Sintered samarium cobalt permanent magnetic material is brittle, and is not suitable to be made into structure parts due to its lack of ductility. Mechanical and physical properties of SmCo5 magnet are better than Sm2Co17, so SmCo5 is easier to produce while Sm2Co17 is more brittle. Magnetized samarium cobalt permanent magnet must be careful handled one by one in assembling process, so as not to be broken when attracts to iron parts, and harm human body in the case of two pieces of magnets attract to each other.
(2) Due to minor collisions during the process of packing and shipping, there will be small visible defects. As long as it doesn't affect the conventional assembling or functioning, the magnetic properties, stability and resistance to demagnetization will not be changed.
(3) Customers who need the SmCo magnets to be supplied in un-magnetized condition shall have clear knowledge of the magnetic energy of their own magnetizing device to select the grade of SmCo magnets of China Rare Earth Magnet Limited that can be magnetized thoroughly.
(4) Should the working environment of products be acid-based or harsh, we can provide zinc, nickel, gold or epoxy as protective plating for samarium cobalt permanent magnet products. Thank you for using our samarium cobalt permanent magnet products, welcome to fax or email your inquiry. It is our honor answer technical questions from you, and will strive to supply high quality samarium cobalt permanent magnets with favorable prices.
