AMF Magnetics Supply Alnico Cylinder Magnet, Alnico Rod Magnets and Alnico Cow Magnets. Alnico Cylinder and Rod magnets are used for seals, sensors, coin collection machines and most famously, in guitar pickups. Amplifiers, actuators and motor applications have also used Alnico magnets due to their impressive flux density.
Cow Magnets are used by dairy farmers and veterinarians to help prevent Hardware Disease. Hardware Disease is caused by cow’s grazing and ingesting stray metal particles such as nails, staples and tramp iron. Cow Magnets work by attracting these metallic objects in their stomachs before damage occurs.
Alnico magnetic alloys are resistant to corrosion and can withstand high temperatures. Their magnetic field is sensitive to demagnitisation. Alnico alloys aren’t as strong as permanent magnets like Rare Earth Magnets & Ceramic Magnets. However, their mechanical strength is greater.
