Product Description

Product Description
NdFeB magnet with its excellent magnetic, known as "magnetic king". NdFeB contains a large number of rare earth elements,  its characteristics of hard and brittle. Vulnerable to oxidation corrosion on the surface, NdFeB surface coating treatment must be conducted.
 
Our advantage:
1. Our company has own production factory, can detect quality at any time.
2.  Our products cover more than 95% of the performance range of the current magnetic materials industry, which meets the need of various products in every walk of life. 
3. The surface coated: Ni (Nicuni, Black Nickel); Zn(Cr3+Zn, Cr3+czn);  Au; AG; Black Epoxy etc
4. The main products are N33-N50, N33H-N48H, N33SH-N45SH, N33UH-N42UH, N28EH-N35EH, etc. which all passed the ISO9001 quality management system certification.
 5. Smaller volume, lighter quality.
6. To make shapes according to customer's requirements.
7.Strict quality requirements, the gap between the range within 0.1 and 0.05 mm
