Wholesale Alnico 5 Magnet Guitar Pickup Alnico bar Rod Magnets

AlNiCo magnet is composed of Aluminum, Nickel, Cobalt, and a few transition metals. They have excellent temperature stability, high residual induction, and relatively high energies. The most common type of magnet found in a pickup is most definitely Alnico. 

Alnico Bar Magnet is used in mining, plastic, ceramic, electric power, chemical, rubber, pharmaceutical, food, environmental protection, remove impurities, purify liquid. Various structures can be chosen, the size and number can be made as your needs.

Sintered AlNiCo magnet properties

Features

• Alnico bar magnets offer excellent temperature stability, high residual induction, and relatively high energies.
• Temperature stability in high thigh-temperature applications, and a maximum working temperature of approximately 1000°F
• Alnico bar magnets may be ground to size but not by conventional machining. We can grind them to your specifications.
• Alnico bar magnets have high residual induction and energy product compared to ceramic magnets, and low coercive force compared to ceramic and rare earth materials (more subject to demagnetization).

The difference between different guitar magnets

Alnico magnets come in three main grades: 2, 3, and 5:

Alnico 2 traces back to the days of the 1950 Telecasters. This class seems to work well for middle-position pickups. It is known by its sweet, vintage tone, and there seem to be little disadvantages to using it.

Alnico 3 is the weakest of the three grades. It contains less cobalt, a core ingredient in the rest of the Alnico family. Because of the decrease in the magnetic pull, it works wonders for neck pickups, where there is the most string vibration.

Alnico 5 is the strongest of the three alnico grades. The tone and response of the magnet are more powerful than its two cousins. This makes it perfect for bridge pickups, where there is the least vibration. If you want an aggressive, in-your-face kind of sound, Alnico 5 is your best bet.

FAQ: 

Q1. Are alnico magnets better than ceramic?
A1. Alnico pickups tend to be lower output than most ceramic pickups. Because of this, they generally won't push an amp as hard and they'll clean up better than ceramics pickups. This all depends on what grade of alnico is used in the pickup, alnico II vs. IV, for example.

Q2. How long do alnico magnets last?

A2. They last as long as neodymium magnets and are used today in high-temperature applications, applications requiring low coercitivity, mass production instruments and legacy applications in which the material has been designed.

Q3. Can you cut an alnico magnet?

A3. Magnets are extremely hard and brittle. Alnico magnets can be cut with abrasive wheels and carborundum grinding wheels and coolant.

Q4. What is the best alnico magnet?

A4. Alnico VIII (alnico 8) is the strongest type of alnico magnet. Alnico 8 magnets are typically reserved for high-output pickups and sound very aggressive in comparison to the other types of alnico as they distort much more easily so are the closest to ceramic magnets out of all the different types of alnico.

Q5. Do Alnico magnets rust?

A5. Some grades of alnico magnets do contain traces of iron and therefore will display some light surface corrosion over time if exposed to water.
