NdFeB rare earth magnet Micro motor magnet for sewing machine

NdFeB rare earth magnet Micro motor magnet for sewing machine sintering process Ni coated

Our NdFeB magnets are used in Micro motors because our NdFeB magnets have the following advantages:

1. The coating is very smooth, the resistance is small, wear-resistant and high-temperature resistant;

2. The remanence is large, the strength is high, the working temperature is high, and it is not easy to demagnetize;

3. This material is the most cost-effective material among all the magnet materials on the market.

Our annual production capacity is 3000 tons.
The company with China’s No.1 rare earth miner Chinalco has a strategic partnership, with a complete production chain and a sound quality assurance system.

Customized needs
To Order, please provide the following key requirements:
1. Performance requirements (such as Remanence Br, Intrinsic Coercivity Hcj, Working Temperture, etc.)
2. Shape and size (drawings are available)
3. Magnetizing direction (axial, radial, and other magnetizing angle)
4. Coating material process and thickness (such as Ni, Ni-cu-Ni, Zn (Cr3 +) , Tin, Epoxy, Ni-AG, Ni-au)
5. Tolerance requirements (please pay attention to cost-effective, to avoid excessive quality)
6.Testing requirements
7. Futures requirements
8.Packing and transportation requirements

The performance and maximum processing accuracy of the NdFeB rare earth magnet products provided by our company please refer to the following two tables:
