Neodymium block magnets is an alloy magnet made fromNd,Fe,B and
other metal elements.It is with the strongest magnetism,good
Specifiaction of neodymium block magnets
1. Specification ofNdFeB Magnets:
Chemical composition: Nd2Fe14B.
NdFeB magnets are hard, brittle and easily corrode.
2. Moderate temperature stability
NdFeB magnets lose -0.09 ~ -0.13% of Br/°C.
Their working stability is under 80°C for low Hci Neodymium magnets
and above 200°C for high Hci NdFeB magnets.
3. Excellent strength value
High magnetic performance (Br: 11,000 to 14,500 GS, Hcj: 11,000 to
30,000 Oe, BHmax: 35 to 50 MGOe)
4. Advanced Technology
The choice of Strip casting and HDDR technology in our factory
allows us to make high performance NdFeB of N52 possible. The
standard properties, N33, N35, N38, N40, N42, N48, N50, N52 (M, H,
SH, EH, UH)
5. Extremely resistance to demagnetization
The intrinsic coercive force is over 30,000 Oe, like N35EH and
N38EH property. Maximum working temperature: 80 to 200 centigrade.
Super strong magnetic force and high intrinsic coercive force and
also with precise tolerance
6. Effective surface treatment
Surface treatments have been developed that allow them to be used
in most applications. The treatments include Ni, Ni-Cu-Ni, Zn, Ag,
Au and other special plating. They are good at anticorrosion.
7. Customized Neodymium Magnets
Most of our magnets are customized. They are produced for
customers' specific using, like arc, tile, square, cylinder and
magnetic ring with various sizes. Common specification samples will
be available in stock for your testing first.
