Alnico Teaching Magnet

 

 

Magnet Information

Products

AlNiCo Magnet

Material

Sintered or Cast Aluminum nickel cobalt magnet

Features

1.The high energies and relatively low coercivity
2.The excellent ability to withstand extreme temperature stability
3.High magnetic flux density and resistance to demagnetization from vibration and shock
4.Excellent resistance to corrosion, no coating is needed for surface protecting

Coating

Painted blue and red to draw a distinction between North pole and South pole of magnet.

Shapes

Ring, bar, cylinder, arc, U-shaped, and other irregular shapes could be manufacture according to customers's sample or blue print.

Tolerance

Our standard tolerance is +/-0.01-0.10mm, but if you have specific requirements, please let us know and we will make our efforts to do it.

Applications

Alnico teaching magnets are widely used in industrial and consumer applications where strong permanent magnets are needed; examples are electric motors, electric guitar pickups, microphones, sensors, loudspeakers, traveling-wave tubes, and cow magnets. In many applications they are being superseded by rare earth magnets, whose stronger fields (Br) and larger energy products (BHmax) allow smaller size magnets to be used for a given application.
