High Resistance Samarium Cobalt Magnet

Product Description


Strong Permanent Magnet Cobalt Samarium Magnets Sm2co17 Ring Magnet




SmCo magnets has the highest temperature of 350℃, it has high magnetic properties,excellent temperature characteristic and corrosion resistance.It is widely used in aerospace, electronic instruments, magnetic pumps, high temperature lamps, sensors andother fields.

And it can be produced in different shapes(round, square, ring, tile, bread), different properties (SmCo5 and Sm2Co17), different sizes(Wafer diameter1≤R≤100mm,Square≤130mm)



1. High resistance to demagnetization
2. High energy (magnetic strength is strong for its size)
3. Good temperature stability



Computer disc drives, sensors, traveling wave tubes, linear actuators, satellite systems, motors where temporary stability is vital.


Machining and tolerances:

We achieve dimensional size and tolerance by cutting or grinding with super abrasives. Samarium Cobalt (SmCo) cannot be ground with conventional drilling, turning or milling processes, and must be machined before they are magnetized. Additionally, large or
complex assemblies are usually magnetized prior to assembly. Standard tolerances for Samarium Cobalt magnets are +/-.05mm for ground dimensions. We stocks SmCo magnets in block, ring and disc form in a variety of sizes and grades, and we are fully equipped to produce the size and tolerance that you require.



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.
