Samarium Cobalt magnets Series 2-17 (Sm2Co17)
These Samarium Cobalt magnet alloys are an age hardening type with a composition of two atoms of rare earth Samarium Cobalt and 13-17 atoms of transition metals (TM). The TM content is rich in cobalt, but contains other elements such as iron and copper. Other elements like zirconium, hafnium and such may be added in small quantities to achieve better heat treatment response. By weight the alloy will generally contain 25% of Samarium. The maximum energy products of these alloys range from 20 MGOe to 32 MGOe. These alloys have the best reversible temperature coefficient of all rare earth alloys, typically being -0.03%/°C. The “second generation” Samarium Cobalt materials can also be used at higher temperatures. The most advanced Samarium Cobalt material offered is S3069 which has a guaranteed maximum energy product of 29.5 MGOe minimum. All the SmCo alloys with energy products that are 22 MGOe and higher that MCE offers are made from the Series 2-17 alloy.
Benefits:
Suitable for high temperature applications (depending on alloy up to max. 350 °C)
High corrosion resistance against aggressive media
Usually no coating necessary
Low decrease of magnetic properties with increasing temperature due to high Curie temperature
SmCo magnet is composed of Samarium, Cobalt, and a few transition metals. SmCo magnet is high performance, low temperature coefficient rare earth permanent magnet, and could keep their performance under the maximum working temperature up to 350 degree centigrade. 10x2x3mm Through Thickness Poles Sm-Co Block Magnet YXG-28H
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.
