Features:
1) Actually the small block magnet with big radius is very hard to produce.We developed our own equipment to manufacture it.
2) Size: 2.5*3.8*1*R1.2mm
3) Grade: N45/N35
4) Special processing technic, we produced with our unique equipment.

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.
