Product Description


Samarium Cobalt Magnet SmCo Magnet with Countersunk hole Ring Magnets






Samarium Cobalt (SmCo) Magnets for High Temperature Applications


Samarium Cobalt (SmCo) magnets are strong permanent magnets with exceptional magnetic properties. They offer excellent temperature stability and a high resistance to corrosion or demagnetization. Part of the rare-earth magnet family, SmCo magnets are ideal for applications involving high or very low temperatures, where magnetic stability is critical, space is a limiting factor and high magnetic strength is required



Samarium–cobalt magnets are available in two "series", namely SmCo5 magnets and Sm2Co17 magnets.


1:5 alloy material

1:5 offers 16 MGOe (energy product) to 22 MGOe and is made up of approximately 50% samarium and 50% cobalt. The 1:5 series 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, 1:15 material may be magnetized with multiple poles, provided that a magnetizing fixture is available.

2:17 alloy material

2:17 offers 24 MGOe to 32 MGOe and is composed of about 25% samarium, 5% copper, 18% iron, 2% hafnium or zirconium, with the remainder being cobalt. The 2:17 series of has 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.

As the magnets have strong attraction and we will use the spacer to apart the magnets each other in case people will be hurt when take it out. Then, they will be packed in a white box of pieces each, several boxes to a carton.

+By Air: If the goods will be shipped by air, all the magnetic should be degaussed and we will use Iron sheet to shield.
+By Sea: If the goods are will be shipped by sea, we will place a pallet on the bottom of cartons.



Express (TNT, DHL, FedEx, UPS, etc), Air, Ocean.
A: The weight is under 40Kgs, we recommend to send them in shielding boxes to you by Express.
B: The weight is between 40Kgs-100Kgs, it can be sent by Express or Air.
C: The weight is over 100Kgs, we recommend to send them by Ocean.
