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.

Physical Properties of Cast Alnico
Curie Temperature (℃)	760-890
Max. Operating Temperature (℃)	450-550
Resistivity (μohm.cm)	47-54
Hardness (Hv)	520-630
Density (g/cm³)	6.90-7.30
Relative Recoil Permeability (μrec)	1.70-4.70
Saturation Field Strength (kOe,kA/m)	2.7-6.3/215-500
Temperature Coefficient of Br (%/℃)	-0.025 ~ -0.02
Temperature Coefficient of iHc (%/℃)	+0.01 ~ +0.03

Applications:

Instruments

Guitar pickups
