Characteristics of Neodymium magnet

Neodymium magnet is currently the strongest one available, best in magnetic performance

and energy.

NdFeB magnet have the characteristics of:

Extreme strong Br residual induction

Very high energy product

Excellent demagnetization resistance capacibility

Coating is needed for NdFeB Magnet which is not suitable for high temperature working condition.

High Coercive Force

Very hight energy products

Low corrosion resistance (when uncoated)

Low mechanical strength – Brittle

Strongest magnetic power

Hight coercive force

Brittle & Hard

Good temperature stability

High resistance to demagnetization

Excellent performance and cost ratio

Available Grades of Neo

Many grades of Neodymium exist to support a variety of industrial and commercial applications. The range of Neo grades is typically 33 to 52 MGOe. These ranges allow for balancing cost, magnetic performance, and operational temperature resistance.

Corrosion Resistance

Neodymium magnets have poor resistance to corrosion and they can also corrode from the inside out if proper pre-treatment processes are not followed. Oftentimes a multi-layer Nickel-Copper-Nickel plating is applied, but this may not be sufficient for all applications.

Temperature Effects

Neodymium magnets are very susceptible to elevated operating temperatures and the application requirements should be considered before selecting a particular grade of Neo.
