Product Description
Product Name: Rare earth NdFeB magnets, Neodymium magnets, Grade N40M
Materials Trademark:
N35-N50, 33M-48M, 30H-45H, 27SH-45SH, 25UH-40UH, 23EH-38EH
All Trademarks are available.
Working Temperature: 80-200(° C)
Product Feature:
Produced by the powder metallurgical method with chemical composition of ND2Fe14B
Very brittle and hard
Poorest corrosion resistance of all commercial magnetic material
High resistance to magnetic demagnetization
Excellent cost to performance ratio
Reasonable temperature stability
Not suitable for application which exposed to high temperatures
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.
