Promotional D20*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 
Technology Advantage: We have professional technical staff, the remarkable technology research center, large 
scale production factory

Price Advantage:We take The centralization, scale production, reduce the cost . In the same quality products,our
 price is cheaper than industry average.

Export Standard Cartons are supplied with foam well protected. We can make the packages according to customer's
 request. Sea packages and air packages are both available
