Slide 1:

Samarium Cobalt Magnets Are Preferred Over Neodymium Iron Boron

Slide 2:

The most common Rare Earth Magnets are Neodynium Iron Boron, but that is not what exactly you are looking for always.

Slide 3:

  Rather you need to ask whether the magnets inside the Tube Magnet is sintered or bonded.     Samarium Cobalt Magnet ( SmCo ) are powerful magnets which is also rare earth magnets, it is composed of samarium and cobalt.  All Samarium Cobalt is sintered and therefore, these magnets work with high temperature applications where neodymium fails to work.

Slide 4:

Samarium Cobalt magnets are commonly used for magnetic couplings, high performance motors and magnetic separators.  The maximum operating temperatures for this magnet is between 250 and 550 °C, whereas standard Neodynium Iron Boron magnets are suitable for applications up to 80° C. In Curie temperature for samarium cobalt, it varies from the range of 700 to 800 °C. Also, Samarium Cobalt subject to less corrosion than a Neodymium magnet, thus, it does not require coating or plating.

Slide 5:

Features Of Samarium Cobalt Magnet: It offers strong resistance to demagnetization Standard tolerances for Samarium Cobalt magnet is +/-.005 for ground dimensions

Slide 6:

Samarium Cobalt 1:5 offers 16 MGOe (energy product) to 22 MGOe , it is composed using approximately 50% samarium and 50% cobalt Samarium Cobalt 2:17 offers 24 MGOe to 32 MGOe and is made of 25% samarium, 5% copper, 18% iron, 2% hafnium or zirconium, with the remainder being cobalt

Slide 7:

Both Samarium Cobalt and high temperature Neodynmium Iron Boron magnets maintain their magnetic strength at higher temperatures. However, Samarium Cobalt is significantly more expensive than Neodymium Iron Boron but they do offer stable temperature for very high temperature applications.

Slide 8:

Samarium Cobalt magnet cannot be formed with conventional drilling, turning or milling processes, this must be on ground before they are magnetized. Also, the large or complex assemblies are usually magnetized prior to assembly. All Samarium Cobalt magnets are produced on the range from 0.8 to 1.15 Tesla.
