1. This is the sintered Neodymium magnet, it is the third generation rare earth magnet.
It is the most powerful and strongest magnet in World at present.
2. The arc and segment shape magent is one regular and popular shaped for the sintered neodymium magnet.
Our strong Neodymium arc magnet(segment magnet) is suitable for advanced permanent magnets motor and pump.
3. We are providing the arc magnets with high energy material for motor application, like SH grade, L-SHT grade. These magnets can be assemblied together to a ring and sticked to iron housing. The meterial can work at high temperature and have low weight lost in high speed rotating. The material also have strong torque force.
Besides the basic grades, we also have T and L-T series grades which are derived from these basic grades. The T and L-T grades material are mainly for segment magntes which used in electric motor . The main properties of the derived grades such as Br, Hcj, Hcb and (BH)max are corresponding to those of the basic grades, while other properties are different. You can see, with highertemperature coefficient, this T and L-T material can work at higher temperature and has lower power decline.
4. The
magnets can be coated with nickel, Zinc, epoxy, chrome, stannum or non- coated.
