Characteristics of NdFeB Magnet

Physical Properties:

1. Neodymium Magnets are the strongest magnets in the world. They can lift up to 1000 times theirs own weight.

2. Neodymium Magnets are easy to machine, compared to Alnico and SmCo magnets

3. Neodymium Magnets are with high resistance to demagnetization.

4. The maximum working temperature of magnet is changeable due to ratio of length and diameter and environment factors.

5. Compressive strength MPa: 1050, bending strength:290

6. The perfect coating of neodymium magnet can meet many anti-corrosion requirements. The salt spray test and humidity heat test of the high anti-corrosion coating Nickel+Copper+Epoxy is typically more than one month.

7. The super-high neodymium magnet has a long lifetime with the following specifications; PCT: 120°C, humidity 100%, vapor pressure 2 bar, 4-7 days, average low weight loss<3mg/cm2

Magnetic Property of NdFeB Magnets:
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,AH)

Shape:Disc, Ring, Block, Segment, Cylinder, Trapezoid, Customized Design (Design proper magnets for clients’ specific requirements)
