Samarium Cobalt (SmCo) magnets are made by a sintering process and exist in two forms. The first is Sm1Co5 (SmCo 1:5) and this has a maximum energy product of between 14 and 24 MGOe. 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 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). Praseodymium (Pr) may also be used. Sm1Co5 is made of only Sm and Co and has excellent corrosion resistance. We offer 29 grades of sintered SmCo and 7 main grades of bonded SmCo. SmCo26 (a 2:17 variety) is the most commonly used grade.

Sm2Co17 Arc Segment Magnet YXG-30

Extremely strong rare earth magnets, Samarium Cobalt magnets (SmCo) are composed of samarium, cobalt and iron. Not sure if samarium cobalt is the best material for your application? Review our permanent magnetic materials comparison for more information.

Manufacturing – In general, the elements are melted together and milled into a powder that is dry-pressed to shape in the presence of a magnetic field. The material is then sintered, aged, ground to dimension, magnetized and tested. They are called “rare earth” magnets because the elements of samarium cobalt are classified as such in the lanthanides section of the Periodic Table of the Elements. Customized Tile Arc Sintered Smco Rare Earth Magnet

Tolerances – For as-pressed material, tolerance on the thickness (direction of magnetization) is +/- .005”. Other dimensions are +/- 2.5% or +/- .010”, whichever is greater. Sm2Co17 Tile Arc Samarium Generator Permanent Magnet

According to International Magnetics Association (IMA) standards, visual imperfections such as hair-line cracks, porosity and minor chips are commonly found in sintered metallic magnets. A chipped edge is considered acceptable if no more than 10% of the surface is missing. Cracks are acceptable as long as they do not extend across more than 50% of pole surface.
