Super strong sintered samarium cobalt cylinder shape smco magnet for sensors
About Smco magnet
Samarium cobalt magnet is a rare earth magnet. It is made from samarium, cobalt, and other metal rare earth materials through mixing, smelting into an alloy, and then crushed, pressed, and sintered. SmCo magnets have a high magnetic energy product and extremely low-temperature coefficient. Their maximum operating temperature can reach 350℃.

Grade: SmCo1:5(SmCo16, SmCo18, SmCo20, SmCo22,SmCo24), SmCo2:17(SmCo24, SmCo26, SmCo28, SmCo30,SmCo32)
SmCo1:5 magnet is also name smco5, prorated with metallic Samarium, Cobalt and Metallic praseodymium, are firstly these rough casts with different properties and grades after series technology processing from melting, milling, and pressing to sintering in order.
The (BH)max range is from 16 to 24 MGOe, maximum working temperature 250 ℃. The Physical Character and Ductibility of SmCo5 is better than Sm2Co17, so SmCo 5 is slightly easier to be machined thin thickness disc or ring wall and complex shapes while Sm2Co17 is more brittle. Magnetization magnetic field of SmCo5 is lower than Sm2Co17’s.
Smco2:17 magnet is also name Sm2Co17. Prorated with metallic Samarium, Cobalt, Copper, Iron And Zirconium. Are firstly those rough casts with different properties and grades after series technology processing from melting, milling, pressing to sintering in order.
The (BH)Max range is from 24 to 32 MGOe, Maximium working temperature 350 ℃. Sm2Co17 bears a extremely low temperature coefficient and preferably anti-causticity. In high-Temperature conditions, the magnetic properties is better than NdFeB magnets, as a result, it’s widely used in fields such as aeronautics and space, national defense and sensors.
In General SmCo5 can be magnetized saturated by 4000Gs magnetic field, however, magnetizing Sm2Co17 with high Hcj Value need more than 6000Gs Magnetic field.
The price of SmCo5 is more expensive than Sm2Co17. According to different using circumstance, customer can choose SmCo5 or Sm2Co17 reasonably.
Shape: Disc, Ring, Block, segment, Cylinder, Trapezoid, Customized design(Design proper magnets for clients specific requirements)
Characteristics: High performance, low terperature coefficient, high working temperature 350 ℃, It doesn’t need to be coated because it is difficult to be eroded and oxidized.
Application: Motors, Aviation and spaceflight, National defense and military affairs, Microwave appliance, Medical apparatus, Auto industry, Machine gearings, sensors, meters and instruments.
