NdFeB permanent magnet is mainly used in Micro-motor, Electronic Industry, Car Industry, Petrochemical, NMR devices, Sound equipments, Maglev System, Magnetic drive and Magnetotherapy system, and its also used in Motorbikes, Car oil-duct's magnetization, with the aim of saving oil.
Earth permanent magnet (NdFeB) has the strongest magnetism nowadays. It does not only has high remanence, high coercivity, high energy product, and high-functional, but also it can processed into a variety of sizes easily. Now, it is widely used in avigation, spaceflight, electron, electrical sound, electrical machinery, apparatus, meters, medical technology, and especially apply to develop high-performance, small and light replacements.

Our factory produce and manufacture magnets according to customer's design on shape, dimension, grades, coatings etc.
To offer you our magnets price, please offer the following details:
Magnets grade: From N35 To N50, from N Series to UH Series.
Magnets size: As the drawing
Magnetism direction: Which direction to oriented The north pole and south pole
Magnets coating: Nickel, Zn, Black Epoxy, AG, Au etc.
Quantities: More mass order quantities. More Lower the prices. Original factory.

If you haven't been able to find your desired size or strength in our website?
We can send you a price quotation for exactly the magnet you wish...At no obligation to you. Here's how it works:
We can offer you not only standard forms (Disc/Rod, Block, Cube, Sphere, Ring). But also special demands, like borings, grades, countersinks, pole markers, etc.
Tell us which features you desire in a magnet (shape, size, strength, surface coating, and temperature resistance) and the quantity you will require.
You will receive our price quotation via e-mail within a day.
You will be under no obligation to buy.

When inquiring or ordering, please send us following information
1. Type of magnet (material & grade)
