Also, Samarium Cobalt magnets are ideal for very low temperature applications (SmCo can be used down to a few Kelvin above Absolute Zero) making them a first choice magnet for cryogenic applications. The SmCo magnets start to outperform the NdFeB magnets around 150-180 degrees C. A few Neodymium magnet grades can be used at temperatures up to 220 degrees C.
Samarium Cobalt (SmCo) magnets can be used over a massive temperature range.
The SmCo magnets work over a wider temperature range, have superior temperature coefficients and have much greater corrosion resistance. Samarium Cobalt (SmCo) magnets are not as strong as the Neodymium (NdFeB) magnets (maximum energy product of between 30 and 50 MGOe) but they have three significant advantages. Samarium Cobalt is also known as SmCo, Rare Earth Cobalt, RE Cobalt, RECo and CoSm. SmCo26 (a 2:17 variety) is the most commonly used grade. We offer 29 grades of sintered SmCo and 7 main grades of bonded SmCo. Sm1Co5 is made of only Sm and Co and has excellent corrosion resistance. The main Sm2Co17 alloy is around 35% Samarium (Sm) and 60% Cobalt (Co) with the balance being from varying amounts of Iron (Fe), Copper (Cu), Hafnium (Hf) and Zirconium (Zr). The second, and more common, form is Sm2Co17 (SmCo 2:17) and this has a maximum energy product of between 22 and 32 MGOe. The first is Sm1Co5 (SmCo 1:5) and this has a maximum energy product of between 14 and 24 MGOe. Samarium Cobalt (SmCo) magnets are made by a sintering process and exist in two forms.
