Brief production
They are called rare earth because their composition elements found in the "Rare Earth" or Lanthanides
portion of the Periodic Table of Elements. Neodymium magnets (Nd-Fe-B) are composedof neodymium, iron, boron and a few transition metals. Samarium cobalt magnets (SmCo)
are composed of samarium, cobalt and iron. These rare earth magnets are extremely strong for their small size, metallic in appearance and found in simple shapes such as rings, blocks and discs.
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 +/-0.05” for ground dimensions. Adams 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, 1:5 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.
General Features of SmCo
1.High performance at a competitive price
2. Shape: block, disc, cylinder, arc, sphere
3. 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

Power warnings
Be careful when deal with strong rare earth magnet.
Please use caution when handling magnetized Samarium Cobalt magnets, their exceptional magnetic force may cause them to attract to metal (or to each other) so strongly that fingers in their path could prove painful.
