Ferrite Pot Magnet
Different Holding Magnets, such as Square, Disc and Ring Holding Magnets, Hard Ferrite (Ceramic), Alnico, NdFeB and SmCo assemblies are specified for many applications to all industries and enigneering. These magnets are made by setting ferrite, Alnico, NdFeB and SmCo magnet in steel parts (and/or some non-ferrite magnetic insulate materials, such as Brass and Aluminum), and are avaiable in many different forms and shapes, which are finished in white, black, gray, Nickel or Zinc coating,or rubber covered. A holding magnet has a particular magnetic circuit that can concentrate or insulate magnetic power at a target space around the magnetic assembly.Ferrite Pot Magnet
