Product Description

 

Irregular Alnico 5 Magnet 5koe With Permanent Casting For Receivers

 

Quick Detail:

 

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

2. Manufacturing process - casting (most common)

3. Density - 7.3 g/cm3

4. Saturation magnetizing field required - about 5kOe.

 

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.
