Coating for your convenience:
Neodymium magnet are composed mainly of neodymium, iron and boron.if that are not plated, the iron in the material will oxidize very easily, particularly is exposed to moisture. Even normal humidity will rust any iron anywhere over time.
Nickel is the most common choice, as it is durable and cost-effective.Our magnets are costed with a triple plating of nickle-copper-nickle.This created a shiny siliver finish and provides dependable resistance to corrosion in most applications. It is important to remember that no neodymium magnet,even with a plastic or gold coating, is completely waterproof.
Production Flow :
For the next 25 years Jintong was one of the leading neodymium magnet manufacturers and shipped an average of 1 to 2 tons of finished neodymium magnetic material per month. We are constantly striving to add complimentary functions in order to consistently deliver value to the market place.
