General Characteristics: 

1. SmCo is also named with SmCo magnetic steel, SmCo permanent magnet, SmCo permanent magnetic iron and rare-earth cobalt permanent magnet.  

2. It is a kind of material made from raw earth metal samarium and cobalt and produced by after a serial of process burdening, melting, milling, pressing and sintering.   

3. It is also 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. 

4. It needn’t to be coated because it is difficult to be eroded and oxidized.

Applications of  smco: 

• sensors, magnetic processor, high-end motor
• aerospace, defense industry, microwave devices,communications,
• medical equipment, instruments, wind power, a variety of magnetic drives 

1:5 alloy material 

• Offers 16 MGOe (energy product) to 22 MGOe
• Made up of approximately 50% samarium and 50% cobalt.
• Has a maximum recommended operating temperature of 250°C.
• SmCo 1:5 magnets require lower field strengths than 2:17 materials to magnetize.
• In some instances, 1:5 material may be magnetized with multiple poles, provided that a magnetizing fixture is available. 

2:17 alloy material 

• Offers 24 MGOe to 32 MGOe
• Composed of about 25% samarium, 5% copper, 18% iron, 2% hafnium or zirconium, with the remainder being cobalt.
• Thas a maximum operating temperature of 350°C.
• Special grades of 2:17 are available which can operate to even higher temperatures.
• SmCo 2:17 requires extremely high magnetizing fields, and multiple pole magnetization is not possible
