Product Description

Neodymium (NdFeB) magnets are the third generation of rare earth magnets and are the most powerful and advanced commercialized permanent magnets today. Since made from Neodymium, one of the most plentiful rare-earth elements, and inexpensive iron, Neodymium magnets offer the best value in cost and performance. The sintered Neodymium magnets can offer the highest magnetic properties (33 MGOe to 51 MGOe).

1. Chemical composition: Nd2Fe13B.

Neodymium magnets are hard, brittle and easily corrode.

2. Moderate Temperature Stability

Neodymium magnets lose -0.09 ~ -0.13% of Br/°C. Their working stability is under 80°C for low Hcj Neodymium magnets and above 200°C for high Hcj Neodymium magnets.

3. Excellent Strength Value

The highest (BH)max can up to 51MGOe.

4. Advanced Technology

The choice of Strip casting and HDDR technology in our factory allows us to manufacture the higher performance Neodymium magnets which are over N52 grade possible.

5. Extremely resistance to demagnetization with Hci

The intrinsic coercive force is over 33,000 Oe.

6. Effective Surface Treatment to Prevent Corrosion.

Surface treatments have been developed which allow the Neodymium magnets can be used in most applications. The surface treatments include nickel, Ni-Cu-Ni, zinc and tin plating and epoxy resin coating.
