NdFeB magnet Pentagon with a hole centrally
Product picture:
Features:
1) This Pentagon shape magnet used in electrical, in the center with a hole.
2) Special processing technic,
3)Tolerance:+/-0.05mm
4)Coating: Nickle (≥15um)
Characteristic of Sintered NdFeB:
1. Neodymium magnets are hard, brittle and easily corrode.
2. Neodymium magnets lose -0.09 ~ -0.13% of Br/ ° C. They areworking stability under 80 ° C for low Hci and can reach 200 ° Chighest working temperature for high Hci.
3. Excellent strength value . The highest (BH)max reaches up to 52MGOe .
4. Strip casting and HDDR technology allows us to make high performance NdFeB over N52 possible.
5. Surface treatments have been developed that allow them tobe used in most applications. The treatments include gold, nickel, zincand tin plating and epoxy resin coating.
