Stronger anisotropic alnico has a fixed DoM axis. Weaker Isotropic alnico takes complex magnetic fields. Keeping within normal grades is advised but bespoke Alnico magnets are available. Alnico produced to specific Br, Hc, Hci and BHmax may be possible but at extra cost. A refinement of the established Moving Magnet principle, they offer an excellent combination of exceptional tracking ability, dynamic range and longevity, thanks to the extremely high quality components used for their construction. It is common for the magnet pole faces to be machined to finish. Meanwhile, back with the Audio Note rig, I was impressed with the IQ3 moving magnet cartridge (980) which has the same stylus and cantilever as their IO1. The Audio Note IQ cartridges are the finest Moving Magnet designs currently available. Alnico5, Alnico 8 and Alnico 9 all exist with several sub-grades with differing performance characteristics. ![]() Cast Alnico 5 is the most common grade of Alnico, with the LNG44 variant of Alnico 5 (Alcomax 3) being the most popular. Isotropic magnets can be magnetised in many ways as they have no preferred direction of magnetisation but give reduced performance. ![]() Anisotropic magnets have the direction of magnetisation (DoM) permanently within the structure and give the maximum performance. Sintered Alnico magnets are not so commonly used due to lower magnetic performance and limitation to simpler shapes. Casting Alnico is cost effective for both low and high volume, for small and very large magnets. Casting my memory back to 1992 I had an eighteenth birthday coming up and deciding to be different to my. Cost: TT-2 Deluxe black 2838.00 GBP, Arm 2 1028.50 GBP ( Currency conversion) ( YMMV ) Reviewer: Graeme Budd - TNT France. Casting is often used to get “near net shape” Alnico magnets. Product name: Audo Note TT-2 Deluxe Turntable with AN Arm 2. Cast Alnico is the most common form of Alnico magnet. They can be produced by Casting or Sintering. ![]() They retain approximately 85 of room-temperature magnetization at temperatures of up to 1,000☏. They have the highest operating temperature and temperature stability of any permanent magnetic material. Alnico magnets should be regarded as the best choice in extremely high temperature applications. Alnico magnets are alloys comprised of aluminum, nickel, iron, and cobalt. They are an alloy of Aluminium, Nickel and Cobalt hence the term Al-Ni-Co. They are also somethimes shown as Alcomax, Columax, Hycomax and Ticonal brands.Īlnico magnets have the best temperature coefficients of any magnet material. Alnico magnets are a best choice in extremely high temperature applications.Īlnico magnets are Cast or Sintered. Alnico magnets have the best temperature coefficients of any magnet material.
