1. What are neodymium magnets? Are they the same as “rare earth”?
Neodymium magnets are a member of the rare earth magnet family. They are called “rare earth” because neodymium is a member of the “rare earth” elements on the periodic table. Neodymium magnets are the strongest of the rare earth magnets and are the strongest permanent magnets in the world.
2. What are neodymium magnets made from and how are they made?
Neodymium magnets are actually composed of neodymium, iron and boron (they are also referred to as NIB or NdFeB magnets). The powdered mixture is pressed under great pressure into molds. The material is then sintered (heated under a vacuum), cooled, and then ground or sliced into the desired shape. Coatings are then applied if required. Finally, the blank magnets are magnetized by exposing them to a very powerful magnetic field in excess of 30 KOe.
2)high working temperature:the AH series with 40 k Oe super-high coervice force can replace SmCo magnets successfully.
3)high consistency:the cpk of Br and Hcj are much higher than 1.67 the consisitency of surface magnetic field and magnetic flux can be controlled with +/-1%
4)High Anti-corrosion:the sale spray test and humid heat test of the high anti-corrosion coating could be more than 1000 hours
5) low weight loss
PCT:130c ,humidity 100%,vapor pressure 2.7 bar.20 days,average low weight loss less than 2 mg/cm2
