Square samarium cobalt magnet
Chemical composition: Smco5/Sm2co17
High anti demagnetization and good temperature characteristics.
Generally does not require surface treatment; And it has high temperature stability and good corrosion resistance.
Surface treatment can also be carried out according to customer requirements, and different sizes and shapes can be processed.
Widely used in other fields such as instruments and meters.
