Cast Bar AlNiCo Guitar Pickup/Guitar Parts Magnets

Alnico magnet material is made by alloying aluminum, nickel and cobalt with iron. Some grades also contain copper and/or titanium. The alloying process is casting or sintering. The process and the heat treatment needed to optimize magnetic properties produces hard (Rc45) and brittle parts that are best shaped or finished by abrasive grinding. Cast parts are generally under 70 pounds and may be used as-is, but polar surfaces are usually ground flat and parallel. Sintering is confined to high volume parts in sizes under one cubic inch and an effective press length to diameter ratio under four.

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.

Sometimes, though, the pole pieces are themselves magnets, which means one is required for each string, or two per string if it's a humbucker. On some occasions, though, a single bar magnet is used inside the coil itself, also doubling as a blade pole piece for all strings together.

Because every little variation in pickup construction makes a difference to its sound, the type and positioning of the magnets is significant.

Magnets of different compositions are also used in different pickup designs, and these play a big part in shaping these components' sounds, too. Following are the main types and their characteristics:
