Project Description

What Are Miniature Magnet SmCo?

Miniature Samarium Cobalt (SmCo) magnet is micro permanent rare earth magnet made from samarium cobalt alloys.

The micro magnets are commonly found in bonded magnet materials because the bonding material is more flexible. Although SmCo material is very hard and brittle, China Magnets Source has advanced machining, laser equipment, and experienced machinists, which can provide various customized sizes of miniature samarium cobalt magnets and also can make small magnets in neodymium and alnico materials.

Mini SmCo Magnet Specifications:

  • Material: SmCo5 & Sm2Co17
  • Production process: cutting, grinding
  • Size: custom according to request
  • Tolerance: depending on actual design
  • Multi Shapes: cylinder, disc, ring, block, segment, bread shaped, U shaped and other irregular shapes
  • High Operating Temperature: Smco magnets can operate up to 350°C.
  • Strong Holding Force: Their magnetic force is very high as compared to ferrite magnets and alnico magnets.
  • Excellent anti-corrosion & anti-oxidation properties: no need to carry out surface anti-corrosion treatment, the magnet can be used for a long time.

Miniature SmCo Magnet VS Small Neodymium Magnet

SmCo magnets, as a rare-earth magnet, have an extremely high resistance to demagnetization by external magnetic fields. They are like NdFeB magnet that have great magnetic strength when compared to their volume. And unlike neodymium iron boron magnets, samarium cobalt magnets are more resistant to high temperature and corrosion, making them a good complement to neodymium iron boron magnets.

SmCo Tiny Magnet Application

Many of our customers purchase tiny small samarium cobalt magnets to use in their high – end precision instruments, such as semiconductor, optical Isolator, watch movement, smart locking system, avionics Systems, micro motor and medical devices, etc.
