Ames Laboratory will partner with Electron Energy Corporation to improve a mainstay of magnet technology— the samarium cobalt (SmCo) magnet. They are known for their high magnetic strength, exceptional temperature resistance, and reliable performance without oxidation protection. Samarium cobalt magnets (SmCo) are composed of samarium, cobalt and iron. Warning: Maximum pull ratings are based on direct contact with rust-free and unpainted iron plate. The magnet rivals widely used "Alnico" magnets in magnetic strength and has the potential to fill a strong demand for rare-earth- and cobalt-free magnets in the market. Actually, sintered Samarium Cobalt magnets are not suitable to be structure part due to inherent brittleness. As a result, they are more suitable for certain applications than Neodymium magnets. SAMARUIM COBALT MAGNETE. (top), Samarium Cobalt (SmCo) magnets have excellent temperature stability while maintaining their magnetic properties in extreme temperature conditions. NdFeB . Samarium Cobalt (SmCo) magnets are strong permanent magnets with exceptional magnetic properties. How it is used in a magnetic circuit will affect its performance. Atoms are the basic building blocks that come together to form molecules, which come together for...

Samarium cobalt is a type of rare earth magnet material that is highly resistant to oxidation, has a higher magnetic strength and temperature resistance than Alnico or Ceramic material. The maximum operating temperatures for Samarium Cobalt magnets are between 250 and 550 °C; Curie temperatures range from 700 to 800 °C. Samarium Cobalt (SmCo5 or Sm2Co17) and Neodymium-Iron-Boron (Nd2Fe14B) are both Rare Earth Magnets –the strongest known rare earth permanent magnets. Samarium cobalt magnets, like other permanent magnets, have a high energy density, good temperature resistance and extremely high coercive field strengths. Since the introduction of rare earth magnets in the 1970s, Electron Energy Corporation (EEC) has been the preferred source for manufacturing and supplying samarium cobalt magnets (SmCo). Many grades of Samarium Cobalt exist to support a variety of industrial and commercial applications. A samarium- cobalt (SmCo) magnet, a type of rare earth magnet, is a strong permanent magnet made of an alloy of samarium and cobalt.They were developed in the early 1970s by Albert Gale and Dilip K. Das of Raytheon Corporation. Regular price $3.68. 16-32 MGOe), high coercive force and high remanence. EEC’s SmCo 33 grade material is one of the highest performance materials available, ideal across a range of applications, from biomedical equipment to microwave signal amplifiers. Comparison with neodymium magnets. The SmCo magnets can be used from temperatures nearly as low as absolute zero (-273°C) up to +350°C. x 0.187'' Thk.¸ 4.22 lbs. Samarium Cobalt magnets offer strong resistance to demagnetization. Therefore, they require careful handling and packing in order to prevent injuries or damages to the magnets. You're currently reading page 1; Page 2; Page Next; Show per page. Samarium Cobalt (or SmCo) magnets are strong permanent magnets made of an alloy of samarium and cobalt. Up to 150 degrees Celsius neodymium magnets are considered to have the best magnetic performance of all permanent magnetic materials, but when elevated to temperatures above 150 degrees Celsius their magnetic strength will be reduced below that of a magnet of the same size magnet made from samarium cobalt material. Samarium Cobalt and Neodymium Iron Boron both make very strong magnets. ©2020 adamsmagnetic.com.
