After the magnets are molded they are heated to 935°C (± 5°) and cool in a magnetic field of proper shape and intensity. They are then held at 1290°C (± 5°) for the required time and held for one hour at 627°C (± 5°) and four hours at 550°C (± 5°). The magnets leave the aging process magnetized and are de-magnetized so they can be finished or surface ground to the proper dimensions.

We get all our Alnico magnets un-magnetized for special magnetizing and calibration. We have several magnetizers and custom built calibrators needed for special pickups and applications. I like using a DC Electromagnet and often use a permanent magnet to magnetize various pickups. We use an adjustable pole piece for various rod and bar magnets made from soft iron.
