Dry granules of Alnico material are compacted under high pressure in metal dies and is used for lower grade Alnico’s. Sintered Alnico magnets has a different chemical composition as compared to cast Alnico’s. Some of the various grades are: Sintered Alnico 2 10 Al, 19 Ni, 13 Co, 3 Cu, Bal. Fe. Sintered Alnico 5…

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…

Rod magnets are made very similar to the Alnico bar magnets with the exception of many rods approximately 6.5 to 11.5 inches long inserted into sand, removed and the molten magnet is poured in each cavity. Typical rod magnets used in pickups with the diameter of .187″ start out at approximately .194″ in diameter. For…

All grades of cast Alnico magnets can be made by Shell or Baked sand molding. Sand casting in “Green” sand is used for larger magnets. The cast Alnico are typically molded in this way too for many shapes and fabrications. Investment casting, also known as lost wax casting, is done when the complexity of a…

It is a proven fact that magnets can lose strength over time and outside elements such as: Outside electrical fields: Soldering guns should never be used to work on your guitar electronics or pickup modifications as the coil has a strong electro-magnetic field that can degauss the magnet within your pickups. Being in contact with…

Yes. Changing your magnet will most likely change the sound in your pickup. If you use a stronger magnet, you will probably hear a little more output and a brighter sounding pickup. If you use a weaker magnet, you will probably hear a warmer sweeter tone. The weaker magnets are my favorite and I’ve often…

Magnet that are pressed into the Vulcanized Fibre flatwork should not be move or adjusted. The beginning of the coil and magnet wire are wound directly around the rod magnets that are pressed into the flatwork. If you try to move the pole pieces for better string balance you can permanently damage the coil from…

You can use rod magnets in place of the studs and make sure the correct polarity is proper on the stud side of the humbucker. The stud polarity should be opposite from the adjustable side which is normally South polarity. You should have all the North polarity rod magnets facing up. The pickup will probably…

You can flip the magnet over 180 degrees to change the magnetic polarity of the pickup and you can adapt magnets of different materials such as Ceramics, Alnico 5, Alnico 4 and different dimensions to your needs. If you use different magnets, make sure you secure or have the pickup potted to eliminate unwanted feed…

Magnets manufactured today may have closer tolerances than products made 40 or 50 years ago. Over time the magnet can be altered by age, heat, shock or other outside electrical elements such as transformers or other magnets. Companies try to keep tight tolerances when being manufactured but some are not always kept. When I say…
