4. Advanced Technology
The choice of Strip casting and HDDR technology in our factory allows us to make high performance Neodymium Magnets 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.
