Magnets and pickups do not have sounds, a magnet's sonic result in guitar pickup application depends primarily on the strength of the magnet.Ceramic magnets are usually stronger than their Alnico counterpart, therefore they sound brighter. The magnets and output, and wire for that matter, can all be used to balance each other out. we offer Alnico 2, 3, and 5 the following chart shows the respective magnets' properties

Material  Common Rod Size(mm)
Alnico2    D5* 13.5    D5*17.5   D5*18
Alnico3    D5*13.5  D5 * 16   D5 * 16.5   D5 * 17   D5 * 17.5  D5 * 18   D5 * 13.5
Alnico5    D4.8 * 22  D9.6 * 22  D5 * 13.5   D5 * 16  D5 * 16.5  D5 * 17  D5 * 17.5  D5 * 18  
Alnico5     D5 * 18.25   D5 * 19   D5 * 20   D6 * 17   D6 * 18   D6 * 20

Alnico rod  Guitar Magnet Feature:
   An ideal material in high temperature applications, which has high operating temperature up to 550°C and above, with excellent corrosion resistance. They can become partially demagnetized if they come in contact with other ferrous materials, special care is required during handling and storing. 

   Usually cast and grinded during production, they are available in various grades depending on its application. Others such as sintered Alnico have lower magnetic properties but offer higher mechanical characteristics.

Alnico Magnet  Advantage:

1. High Temperature resistance

2. Comparatively high magnetic properties

3. Dimensional Stability
