Samarium Cobalt-Magnets SmCo
SmCo magnets pertain, just like Neodymium-Ferro-Boron (Neoflux®) magnets, to the rare earth magnets. SmCo magnets have excellent magnetic characteristics with a maximum energy product of 18 to 30 MGOe, a low temperature coefficient and a high stability. Moreover they are very resistant to oxidation and require no coating under normal circumstances. SmCo magnets are the best choice, especially for applications where durability is of great importance. Think about advanced electronic products, medical equipment and the automotive industry. The maximum usage temperature is approx. 300˚C.
- Pressed out of rare earth materials Sm-Co.
- Machine with diamond tools.
- Provide maximum magnetic force, even with very small dimensions.
- Temperature range: standard up to +250 °C.
- Weather-resistant: do not oxidize.
- Highly resistant to demagnetization.
- Also available in plastic bonded version.
