Ndfeb magnet is easy to rust, oxidation, so ndfeb magnets must surface coating processing.
Nickel plating (
And zinc (
, gold (
, epoxy resin (
And so on.
Ndfeb magnet is widely used in aerospace, electronics, electrical, instrumentation, medical and other fields.
And non-technical areas is becoming more and more widely used.
