NEODYMIUM METRIC

Neodymium (NdFeB)

Developed in 1982, Neo magnets are the strongest magnets available (in terms of energy product). Because of this, they are used in more products and industries than any other permanent magnet. While susceptible to degradation in water and with exposure to intense heat, these downsides can be mitigated through coating, encapsulation and the correct choice of coercivity.
