Smco Magnet

Smco Magnet

Samarium cobalt (SmCo) according to the different components into SmCo5 and Sm2Co17, were sleeping mat and sleeping mat II generation rare earth permanent magnet materials.Because of its raw materials are scarce, expensive and limited its development.Samarium cobalt (SmCo) as the second generation of rare earth permanent magnet, not only have a high energy product (14-28MGOe) and reliable coercive force, and in rare earth permanent magnet series showed good temperature characteristics.Compared with NdFeB, samarium cobalt is more suitable for working in high-temperature environment (> 200ºC).

Detailed Description

Feature:

Samarium cobalt permanent magnet with high energy product and high coercive force, its better than the AlNiCo magnet magnetic, ferrite magnet, the maximum energy product up to 239kJ/m3 (30MGOe), is AlNiCo8 3 PMtimes, ferrite permanent magnet (Y40) 8 times, so SmCo permanent magnet components made of small size, light weight, stable performance.

Application:

can be used for electro-acoustic telecommunications devices, motors, measuring instruments, gyro, electronic watches,microwave devices, magnetic machinery, sensors and other static or dynamic magnetic circuit.

 

what is the Smco Magnet?
Smco Magnet permanent magnet with high energy product and high coercive force, and its magnetic properties than AlNiCo magnets, ferrite magnets, the maximum energy product of up to 239KJ/m3 (30MGOe), is AlNiCo8 3 PM times, ferrite magnet (Y40) 8 times, so the production of SmCo permanent magnet devices, small size, light weight, stable performance.

Smco Magnet applications
Electro-acoustic devices for telecommunications, electrical, instrumentation, gyroscopes, electronic clocks, microwave devices, magnetic machinery, sensors and other dynamic magnetic circuit. Curie temperature of SmCo permanent magnet high temperature coefficient, can be at 300 degree high temperature. Samarium cobalt permanent hardness, brittleness, flexural strength, tensile strength and compressive strength of small structures should not be made.
  Detailed Product Description
SmCo is also named with SmCo magnetic steel, SmCo permanent magnet, SmCo permanent magnetic iron and rare-earth cobalt permanent magnet. It"s a high performance,low temperature coefficient permanent magnet with its high working temperature-350 degree centigrade. When working above 180 degree centigrade, its maximum energy product BH and steady temperature are superior than NdFeB magnetic materials. It needn"t to be coated because it is difficult to be eroded and oxidized. SmCo magnet is widely used in motors, watch,transducers, instruments,positional detector,generators,radar communications,medical equipments, various magnetism spreading devices, magnetic processor,electrical engineering and magnetic derrick.
