Samarium-Cobalt (SmCo) rare earth permanent magnets SmCo magnets are manufactured with sintering or compression bonding. They are anisotropic and can only be magnetized in the direction of orientation. In general, magnetizing fields of approximately 30KOe to 45KOe are required to saturate SmCo magnets. There are two types for alloy materials, 1:5 and 2:17. Characteristics: 1.High magnetic properties The intrinsic coercive force could reach up to 22KOe. 2.Low temperature coefficient For some materials, ¦Á could reach low to -0.01% of Br/¡ãC. 3.High working temperature SmCo The maximum recommended working temperature is 250¡ãC(480¡ãF) for SmCo 1:5 and 350¡ãC(660¡ãF) for SmCo 2:17. The Curie Temperature could reach high to 750¡ãC(1390¡ãF) for SmCo 1:5 and 850¡ãC(1560¡ãF) for SmCo 2:17. 4.High resistance to corrosion No coating is needed for surface protection. . Common applications High performance motors, Magnetic couplings, Magnetic separators, Aerospace defense, Magnistors, Instruments and meters

1. SmCo1:5: SmCo1:5 magnet is also named SmCo5.Prorated with metallic samarium, cobalt and metallic praseodymium , are firstly those roughcasts with different properties and grades after series technology processing from melting, milling, and pressing to sintering in order. The (BH) max range is from 16 to 25, maximum working temperature 250¡ãC. The physical character and ductibility of SmCo5 is better than Sm2Co17, so SmCo5 is slightly easier to be machined thin thickness disc or ring wall and complex shapes while Sm2Co17 is more brittle. Magnetization magnetic field of SmCo5 is lower than Sm2Co17s. In general, SmCo5 can be magnetized saturated by 4000Gs magnetic field, however, magnetizing Sm2Co17 with high Hcj value need more than 6000Gs magnetic field. These days, prices of rare earth materials improved significantly, and the level of rare earth material around the magnet is up to 40%. For these reasons, the price of SmCo5 is more expensive than Sm2Co17. According to different using circumstance, customer can choose SmCo5 or Sm2Co17 reasonably. If customers need more details about SmCo5, please contact our technical adviser in Service and Support. For more information of SmCo5 grade date, please check the SmCo Magnet Performance Parameter Table. Physical properties please tap Application Technology. 2. 17 SmCo magnet: SmCo2:17 magnet is also named Sm2Co17. Prorated with metallic samarium, cobalt, Copper, iron and zirconium, are firstly those roughcasts with different properties and grades after series technology processing from melting, milling, pressing to sintering in order. The (BH) max range is from 20 to 32, maximum working temperature 350¡ãC. Sm2Co17 bears a extremely low temperature coefficient and preferably anti-causticity. In high-temperature conditions, the magnetic properties is better than NdFeB magnets, As a result, it¡¯s widely used in fields¡£such as aeronautics and space, national defense and sensors. As a result of great brittleness of Sm2Co17 materials, it is not suitable for complex shapes and thin thickness disc or ring wall.Due to this character, there may be some appearance defects such as small chips during production, inspection and magnetizing process. However, it would not change its property; we consider them as qualified product. Magnetized SmCo products must be picked up carefully and gently during assemble process and kept away from ironware to avoid mutually attracting, causing chips and cracks. Sm2Co17 magnet is not easy to magnetize saturated, therefore, clients must be familiar with magnetization energy of their own magnetization equipments, to the effect that appropriate grade would be chose and products of company can be fully saturated. Please see magnetizing magnetic field of Application Technology for your reference. According to our customer.

Product Description SmCo magnets, are composed of Samarium, Cobalt, and a few transition metals. SmCo magnets are high performance, low temperature coefficient rare earth permanent magnets, and could keep their performance under the maximum working temperature 350 degree centigrade. Manufacturing Process Samarium, Cobalt, and a few transition metals will be made into the SmCo powder, then fine SmCo powder will be compacted in a die and sintered, fusing the powder into a solid material. There are 2 forms of pressing: die pressing and isostatic pressing. Sintered parts normally need some finish machining in order to meet final tolerances. Machining & Tolerance Generally, SmCo magnets must be machined using diamond-grinding techniques. Sometimes, machining operations may be performed on SmCo materials using carbide tools, but surface finishes thus obtained may be less than optimal. The Standard tolerances for SmCo magnets are +/- 0.1mm for ground dimensions, but sticter tolerances are possible if specially required. Surface treatments The corrosion resistance of SmCo magnets is considered good. Although Surface coating or plating is not generally required for SmCo magnets, all kinds of surface coating are also available, like Nickel, Zn, Ni-Cu-Ni, Gold, Silver, Sn,Chrome, ABS coating, Rubber coating, PTFE(Telfon) coating, stainless steel case, etc. Magnetizing & Packing SmCo magnets require extremely high magnetizing fields, and can be magnetized in any direction as long as it is aligned properly. In some instances multiple pole magnetization is possible with special fixtures. All SmCo magnets are anisotropic, and can only be magnetized in the orientation direction, so particular consideration must be given to this when designing complex assemblies, if it is intended to magnetize after assembly. SmCo magnets are mechanically weak, and magnetically very strong. They should be packed properly in order to help user to use and handle them.

Rare earth samarium cobalt magnets, shorted as SmCo rectangular magnet, are a type of powerful permanent magnet made from the basic elements samarium and cobalt and other metal rare earth materials by mixing, melting, grinding, pressing and sintering. They come in various sizes and shapes, like disc,bar, ring, arc,block, etc.,. Similar to neodymium strong magnets, they belong to the rare earth magnet category, and tcan be classified as SmCo5 and Sm2Co17 according the composition ratios of samarium and cobalt. In comparison to neodymium rare earth magnets, although samarium cobalt magnets may not have as strong magnetic force, they possess two distinct advantages. Firstly, they operate effectively within a higher temperature range, and secondly, they exhibit greater resistance to corrosion. Due to these characteristics, large smco block magnets are commonly employed in applications that demand high operating temperatures, such as generators, pump couplings, sensors, electric motors, marine applications, as well as in the automotive, racing, aerospace, military, and food and manufacturing industries. SmCo rare earth magnets not only perform well at high temperatures but also maintain their magnetic properties even in temperatures below absolute zero (-273 degrees Celsius), making them popular for use in low-temperature applications.
The magnets are composed of neodymium, iron, boron and a few transition metals. Sintered ndfeb magnets are the most powerful permanent magnets available today. It has a combination of very high remanence and coercivity, and comes with a wide range of grades, sizes and shapes such as rings, blocks, discs and segments. With its excellent magnetic characteristics and abundant raw material, ndfeb magnet offers more flexibility in designing of new or replace the traditional magnet materials such as ferrite, alnico and sm-co to achieve high efficiency, low cost and more compact devices. Ndfeb magnet is highly susceptible to corrosion and coating is always necessary. Frequently they are plated in nickel, zinc, tin and epoxy resin.

Attributes of Samarium Cobalt • High resistance to demagnetization • High energy (magnetic strength is strong for its size) • Good temperature stability • Expensive material (cobalt is market price sensitive) Applications of Samarium Cobalt Computer disc drives, sensors, traveling wave tubes, linear actuators, satellite systems, motors where temporary stability is vital. Magnetizing and Handling Samarium Cobalt magnets are very brittle and very strong magnetically. Therefore, it is crucial to handle these magnets with extreme care to avoid personal injury and damage to the magnets. Fingers can be severely pinched between attracting magnets. Magnets can chip if allowed to “jump at” an attracting object. It is highly recommended that when constructing rare earth magnetic assemblies, they be magnetized after assembly. Samarium Cobalt Machining Since Samarium Cobalt magnet material is prone to chipping and cracking, it does not lend itself to conventional machining methods. It can, however, be abrasively ground, but only with the use of liberal amounts of coolant. The coolant minimizes heat fracturing and the risk of fires caused by oxidized grinding dust.
