7.3 g/cm3 Density Alnico 5 Permanent Magnet Block Shape For Guitar Pickup Application

 

 Alnico 5 Block 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.

 

Their Advantage: 1. They have stable temperature coefficient and great for heat applications. The working temperature can reach 550-600 °C.

2. High residual induction and energy product compared to ceramic material

3. Low coercive force compared to ceramic and rare earth materials (more subject to demagnetization)

 

Shortage: Cast Alnico Magnet are hard and brittle, not easily to conventional machining.

 

The common grade is AlNiCo 5 and AlNiCo 8.

 

Applications:

 

Instruments

Guitar pickups
