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.

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

Ningbo Bestway Magnet can supply a wide range of customized neodymium magnets according to requests.
Neodymium is the strongest available magnet alloy at up to 52MGOe.
The use of Neodymium results in smaller, more cost-effective magnet solutions replacing older materials like Alnico and Ceramic in many applications.
Magnets can help optimize performance and cost with Neo magnets in grades from 33 to 52MGOe and operating temperatures up to 230°C/446°F.
Stock Neodymium magnets also available.
