Product Description

Permanent NdFeB Magnet

High precision, High challenge, High quality

Neodymium Magnet is a member of the Rare Earth magnet family, and the most permanent magnet in the world. It is composed of Neodymium (ND), Iron (Fe) and Boron (B), which makes them vulnerable to rust if they're exposed to the elements. To protect the magnet from corrosion and to strengthen the brittle magnet material, the magnet is usually coated with nickel.

NdFeB magnets Making process:

NdFeB magnet use Powder Metallurgy Process, proportion of material such as: Neodymium, dysprosium, iron, cobalt, niobium, praseodymium, aluminum, iron, and boron etc., through Mid-frequency Induction Furnace smelting to alloy steel ingot, then broken into power of 3~5um, and forming mold in magnetic field, the green bodies sintering dense and tempering in Vacuum Sintering Furnace, that can earn magnetic properties of blank of permanent magnet. After grinding, drilling, cutting and other processing, last via surface finish, it is good NdFeB magnet.

Temperature Characteristics:

Low grade Neodymium magnet may lose strength if heated above 80° C. High grade Neo magnets have been developed to function at temperatures up to 220° C with little irreversible loss.

Grade: N35-N52, 35M-52M, 33H-50H, 33SH-45SH, 30UH-42UH, 30EH-38EH, and 28AH-33AHB.
Coating: Ni, Zn, gold, copper, epoxy, chemical, parylene etc.
Shape: Arc, segment, disc, cylinder, sphere, block, ring, tile, and ect.
Magnetization orientation: Through thickness, axially, radially, multipole, diameter.

NdFeB magnets applied range:

Acoustic: Loudhailer, receiver, microphone, annunciator, sound stage, car audio etc.

Electronics: Watt-hour meter, water meter, noise meter, transducer etc,

Motor: VCM, CDDVD-ROM, dynamo, electromotor, servo motor, Pilot motors, motor, vibrator motor.

Machinery and equipment: Magnetic separator, magnetic hanging.
