Samarium cobalt magnets can be divided into two types: permanent magnets and soft magnets. Permanent magnets are mainly used in magnetic sources, such as motors, generators, pressure sensors and flowmeters. Soft magnets are used for sensing, energy storage and other aspects, such as transformers, inductors and converters.
According to the different alloy composition, samarium cobalt magnets can be divided into SmCo5 type and Sm2Co17 type. SmCo5 has excellent diamagnetic vibration, magnetic conductivity and toughness, which can be used for high temperature work. Sm2Co17 has higher coercive force, magnetic energy product and stability, suitable for high precision, high efficiency, high temperature resistance, radiation resistance and long life.
According to the different shape and size, samarium cobalt magnets can be divided into cylindrical, rectangular, circular, spherical and other forms. Cylinder-shaped samarium cobalt magnets are widely used in various electronic devices. Rectangular samarium cobalt magnet is more suitable for sensors, measuring instruments and other precision devices; The ring samarium cobalt magnet is mostly used in the motor and other equipment.
According to the different use environment, samarium cobalt magnets can be divided into conventional and custom types. Conventional samarium cobalt magnets can meet most of the needs of use, mainly used in the general industrial field; The customized samarium cobalt magnet is designed and manufactured according to the special needs of customers, which is suitable for special industrial, medical, scientific research and other fields.
Permanent samarium cobalt magnets are primarily used in magnetic sources like motors, generators, pressure sensors, and flowmeters. Soft samarium cobalt magnets are utilized for sensing, energy storage, transformers, inductors, and converters.
SmCo5 is characterized by excellent diamagnetic vibration, magnetic conductivity, and toughness, making it suitable for high-temperature work. Sm2Co17 features higher coercive force, stability, and magnetic energy product, which is ideal for high precision, high efficiency, and radiation resistance.
They are available in shapes such as cylindrical (commonly used in electronic devices), rectangular (suited for sensors and measuring instruments), and ring shapes (most frequently used in motors).
Conventional types meet standard industrial requirements. Customized types should be selected when specialized designs are required for niche industrial, medical, and scientific research applications.
Continuous research, innovation, and performance improvements in samarium cobalt magnets will drive wider applications, bringing enhanced options, efficiency, and benefits to industrial production and daily life.
