Samarium Cobalt Magnets

Advanced Material with Excellent Temperature Stability& Corrosion Resistance!

Buy Samarium Cobalt magnets on-line today! MagnetShop.com carries a large stock inventory of Samarium Cobalt (SmCo) magnets, available in a wide range of sizes, not all of which are shown on this website.

Samarium Cobalt Magnets (SmCo) are part of the rare- earth family, and the most advanced, high-strength, permanent magnet material available today. Samarium Cobalt magnets are commonly used in applications involving high or very low temperatures, where magnetic stability is critical. SmCo magnets are also ideal for applications where space is a limiting factor and high magnetic strength is required.

Features & Characteristics of Samarium Cobalt (Permanent & Rare-Earth) Magnets

What are the main characteristics of samarium cobalt magnets? Samarium Cobalt Magnets exhibit excellent corrosion resistance, and do not need to be protected for corrosion. SmCo magnets also offer high-resistance to demagnetization. (top)

What are the best temperatures to use for samarium cobalt magnets? SmCo magnets are very temperature stable - their properties stay within a very narrow range up to about 300° C (570° F). (top)

What are some common applications used for samarium cobalt magnets?  SmCo’s magnetic characteristics are ideal in applications for the marine, automotive, aerospace, medical, military and industrial automation industries where high- temperature performance is critical such as motors, machinery, pumps, medical devices, magnetic couplings, magnetic separators and more. (top)

What grades & shapes are available for SmCo magnets? SmCo magnets are available in a number of different grades that span a wide range of properties and application requirements. We stock SmCo discs in grades 18 and 26, and blocks grades 18 to 33. If you are looking for a different shape, size or grade that what is shown on the site, just let us know by sending us a special request or contact us today.  (top) 

What are recommended bonding applications for SmCo magnets? SmCo magnets are often assembled into products using "superglues" such as Loctite 325. Avoid placing mechanical stress on this material. Always ensure that bonding surfaces are clean and dry prior to bonding. (top) 

► What are some safety precautions that should be taken into consideration when working with samarium cobalt magnets? SmCo magnets are hard and very brittle, and have a very high magnetic strength – they can snap together with great force - please ensure that all personnel handling these magnets are aware to handle them carefully to avoid injury. They can chip or break if dropped or if snapped together - so take special care when handling these powerful magnets! (top) 

► What is a permanent magnet? Permanent magnets represent the majority of magnetic materials available today. A permanent magnet is made from ferromagnetic materials. They have a magnetic field that does not turn on and off like electromagnets. We carry a large stock inventory of permanent magnets in a wide variety of sizes and shapes which include neodymiumalnicoceramic (ferrite) and samarium cobalt magnets. (top)

► What is a rare-earth magnet? Rare-earth magnets are the strongest type of permanent magnets available today. Rare earth magnets product significantly stronger magnetic fields than ceramic (ferrite) or alnico magnets. The two types of rare-earth magnets are Neodymium and Samarium Cobalt magnets, both of which are available for on-line purchase on the site.  Click here to learn more about the elements of rare earth and other magnetic materials. (top) 

► How are magnets rated? This refers to the maximum strength that the magnetic material can be magnetized to. Magnets are typically rated by their residual induction, coercive force & maximum energy product. Click here for more details (section 4.0).
