AlNiCo Rod Magnets For Guitar Pickups
Alnico rod magnets can have very strong flux output and are stable at high temperatures.A guitar pickup's magnet or magnets provide(s) the power that enables it to do its thing by sensing the movement of the guitar's steel strings when you play.
Different types of guitar pickups use different numbers of magnets, usually one, two, or six, depending on their design. If just one or two magnets are used, they are usually found as bar magnets mounted beneath the pickup's coil, which charge steel pole pieces running through the coil.

Alnico Rod Magnet advantages
Temperature stability in high temperature applications, and a maximum working temperature of approximately 1000°F
Alnico rod magnets may be ground to size but not by conventional machining. We can grind them to your specifications.
Alnico rod 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)
