Magnetic bars are mainly used to filter various fine powders and liquids, iron-containing
impurities in semi-liquids and other materials with magnetic properties. They are widely used
in chemical,food,waste recycling, carbon black and other fields. Neodymium Separator Tube Magnet

NdFeB Magnet:
Neodymium Magnets, also known as NdFeB, NIB, or Neo magnets, are the most widely-used type of rare earth magnets. Neodymium Magnets are made from an alloy containing, amongst others, the elements Neodymium, Iron and Boron (NdFeB). It is the strongest type of magnet and manufactured in a wide range of shapes, sizes and grades and different coatings/finishes. Neo Separator Rod Tube Magnet 20mmX20mmX100mm

The production process:
1. Neodymium magnets are actually composed of neodymium, iron and boron (they are also referred to as NIB or NdFeB magnets).
2. The powdered mixture is pressed under great pressure into molds.
3. The material is then sintered (heated under a vacuum), cooled, and then ground or sliced into the desired shape.
4. Coatings are then applied if required.
5. Finally, the blank magnets are magnetized by exposing them to a very powerful magnetic field in excess of 30 KOe.
