Package usually PCS/CTN, soft material in CTN to protect magnet. CTN/PLT, CTNS/WOODEN CARTON. PLTS/Containers, Wooden Cartons/Containers




1, About performance: We have high performance like N48, N48M, N48SH, N42UH, N38EH, N33AH

2, About working temperature: the AH series with 35k oe high intrinsic coercive force can even replace Smco magnets

3, About the consistency: the cpk of Br and Hcj are much higher than 1.67 the consistency of surface magnetic field and magnetic flux can be controlled with /-1%

4, About Anti-corrosion: the salt spray test and humid heat of the high anti-corrosion coating could be more than 1000 hours

5, And Low weight loss: PCT : 130C, humidity 100%, vapor pressure 2.7 bar 20 days, average low weight loss less than 2mg/cm² 


The only word we can say is, To contact us is not a waste of time, to be our partner WILL benefit for both.
