Cast Permanent Alnico 5 Magnet Block High Temperatu

 

Cast Permanent Alnico 5 Magnet Block High Temperature For Safety Controls

 

Quick Detail:

 

1.  Saturation magnetizing field required - about 5kOe.

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.
