Simotec Samarium Cobalt Magnet
Manufacturer: Shimonishi Giken Kogyo Co., Ltd
Model: Samarium Cobalt Magnet
Feature
- Composed of cobalt and the rare earth element samarium
- Samarium-cobalt magnets have high magnetic properties second only to neodymium magnets
- Compared to neodymium magnets, they have the advantage of being rust-resistant and resistant to high temperatures.
- On the other hand, it is very hard and breaks easily, so it must be handled with care.
- Neodymium magnets are used in different applications depending on the required magnetic strength, environmental temperature, and durability depending on the application.
