Product Description

Containing mainly Nd (neodymium), Fe (iron), and B (boron), the neodymium magnet is currently the most powerful magnet available.
Excellent mechanical strength with energy product about 8 times stronger than anisotropic ferrite magnets.
The neodymium magnet itself is prone to rusting, so nickel plating surface processing is applied as standard.
However, as its temperature resistance is low, care is required when using.
