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 id 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 sliver finish and provides dependable resistance to corrosion in most applications. It is important to remember that no neodymium magnet,even with a plastic or glob coating, is completely waterproof.
More method of coating as below:
Motors,Wind Power,Sensors,Computers and Peripherals,Magnetic Assemblies,Automotive.
Motion Control,Aerospace,Research and Development,Communications,Medical Device and Diagnostics,Home appliance,Other magnetic applications or you can find new application according to your design.
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.
Configure high-end detection equipment The development of proprietary cutting technology, advanced precision machinetight production process control allowed Jintong to remain at the forefront of neodymium magnet manufacturers.
1.Average force meter( Milling particle size inspection)

3.Magnetic testing equipment for measurements of Field Density and Field Strength
4.Hysteresisgraph for magnetic characteristic measurement ect
Durable – These neodymium magnets ( NdFeB ) are Ni+Cu+Ni triple layer coated, which offer a rust resist protection and shining surface to the magnets
Permanent – Strong Holding Power and resistance to magnetization. The magnet power basically last forever
Multi-function – it is good for DIY Art, hand crafting and storage idea. It can be widely use in garage, home, office wall, scientific experiments
Easy to use – No tools required. Quick and easy to assemble. Put them on any magnetic surface. No drill. No holes. No mess.
User Tips – Be careful when separating them apart and putting them together, the magnet would be fragile when they crash each others
How to place an order:
1.About Size: what is the length, width and thickness of the magnets?
2.About coating: the most common coating is NiCuNi and Zinc, of course other coating is acceptable.
3.Grade of magnet: Please check the most suitable grade of magnet you want.
4.About Magnetized direction: Through Thickness? Through Length? Through Width?
5.Please also let us know the quantity you need.
