Product description

7.3 g/cm3 Density Blocks Alnico 5 Magnet For Guitar Pickup Using

Quick Detail:

1. Density - 7.3 g/cm3

2. Manufacturing process - casting (most common)

3. Shapes- blocks, bars

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.
