Promotional D22*10mm Disc magnets SmCo
Product Description
Promotional D22*10mm Disc magnets SmCo
Specifications
1.Attributes of Samarium Cobalt (1)High resistance to demagnetization
(2)High energy (magnetic strength is strong for its size)
(3) Good temperature stability and SmCo magnets can be operated at higher temperature up to 350°C,
(4)Expensive material(cobalt is market price sensitive)
(5) It needn't to be coated because it is difficult to be eroded and oxidized.
2.Common Applications for Samarium Cobalt Magnets
Holding systems requiring very high holding forces, high field yoke magnets, high performance stepper, DC, servo, linear,
and voice coil motors, magnetic bearings, magnetic couplings, loudspeakers, Halbach arrays, headphones, microphones,
magnetic separation, instrumentation, switches, relays, magnetic resonance, sputtering, vacuum deposition, charged
particle beam guidance, particle Accelerators, Undulators, Wigglers, and others.
3.Directions of Magnetization:
(1) Axially Magnetized
(2) Diametrally Magnetized
(3) Radial Magnetized
(4) Multi-poles magnetized
(5) Customzied specific requirements magnetized
