Strong Power Alnico 8 Magnet Round Shape With Ground Surface For Microphone

 

Quick Detail:

 

1.Ground Surface

2. Manufacturing process - casting (most common)

3. Various shapes- blocks, bars, discs, rings, horseshoes, cylinders, etc.

4. Density - 7.3 g/cm3

 

Cast Alnico magnet is composed primarily of Aluminum, Nickel, Cobalt, Copper and Iron. It has very 

good corrosion resistance and high temperature operation.

Although other magnetic materials offer greater energy and coercivity values, the high remanence

 and thermal stability of AlNiCo makes it the most effective magnetic material for certain applications, 

like generator, microphone, lifting, voltmeter and measuring instruments. It is widely applied in high 

stability fields like aerospace, military, automobile and security systems.
