Rare Earth Magnets AlNiCo & SmCo, Ferrite Magnets, Neodymium Magnets, China Speaker Magnets

Dear China Rare Earth Magnet!
AlNiCo permanent magnet is the best what I looking for but it isn't a problem if you need change the type of the magnet. The only important thing is the form what I need (L61x W35.5 x T8.75mm). For example SmCo or Ferrite magnets are ok for me. Hole diameter can be shrink but this diameter is important too. It has to be 30.5mm. So, everything you can use just it will be a magnet with these parameters and form.
