Smaller Size Aluminum Nickel Cobalt , Alnico Magnet Types For Microphones

Aluminum-Nickel-Cobalt Magnet is high-energy permanent magnet, which posses high fluxdensity, high coercive, high energy product and extreme stability for temperature changes. It exhibits good resistance to demagnetization, stability in high temperatures and excellent conduction.

Features of Sintered Alnico magnets

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

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 In many applications they are being superseded by rare earth magnets, whose stronger fields (Br) and larger energy products (BHmax) allow smaller size magnets to be used for a given application.
