| Samarium Cobalt magnets: Samarium cobalt Magnet / SmCo Magnet,Website:http://www.gmexm.com, a type of rare earth magnet, is a permanent magnet and strong magnet which is made of an alloy of samarium cobalt.They are generally ranked similarly in strength to neodymium magnets, but have higher temperature ratings and higher coercivity and excellent thermal stability, resistant to corrosion, resistant to demagnetizing influences. Such high resistance makes it ideal to use the SmCo magnets in medical and the most demanding motor applications.Manufacturing MethodsSamarium cobalt Magnets / SmCo Magnets are manufactured in the following forms:Sintered - fine SmCo powder is co***cted in a die mold and then sintered, fusing the powder into a solid material. There are two forms of pressing for Samarium cobalt Magnets / SmCo Magnets: Die pressing (which involves a hard die into which the powder is placed and then pressed), and isostatic pressing (involving a special "rubber" die into which powder is placed and then pressed with equal force in all directions on the powder). Die pressed parts are smaller than isostatically pressed parts. Although the magnetic properties of isostatically pressed parts are higher, the uniformity of magnetic characteristics is usually lower than that of die pressed parts. Sintered parts usually need some finish machining in order to meet final tolerances.Sintered Samarium Cobalt magnets exhibit magnetic anisotropy, meaning they can only be magnetized in the axis of their magnetic orientation. This is done by aligning the crystal structure of the material during the manufacturing process.Compression Bonded - this is a technique whereby a special form of SmCo powder is blended with a plastic carrier material, die pressed and then heated. Parts made in this way can be of complex shapes and come off the tool with close tolerances, requiring no further finish machining. They have lower energy products than sintered materials - currently in the range of 15 MGOe.Machining & MagnetizationSamarium Coba |
