Product Description

we designed magnets with 3M adhensive.
Due to the strong attraction force, these magnets can be used in office .
3M can be attached to disc magnets, block magnets.


Sintered Neodymium-iron-boron magnet is one kind of the permanent magnets.

Material Grade of NdFeB magnets: 
Magnet N-( N35, N38, N40, N42, N45, N48, N50,N52), 
Magnet M-(35M, 38M, 40M, 42M, 45M, 48M), 
Magnet H-(35H, 38H, 40H, 42H, 45H), 
Magnet SH-(30SH, 33SH, 35SH, 38SH, 40SH, 42SH,45SH), 
Magnet UH-( 28UH, 30UH, 33UH, 35UH, 38UH), 
Magnet EH-(28EH, 30EH, 30EH, 33EH, 35EH) 

1) Application of NdFeB magnet: Toys, package, Printer, Switchboard, Phone, voice coil motors (VCM's) in hard disk drives, high performance motors, brushless DC motors, magnetic separation, magnetic resonance imaging, sensors, loudspeakers etc. 

2) The coating of NdFeB magnets can be Zn, Ni, Ni-Cu-Ni, Epoxy, CR3+ZN, NI+AG, NI+AU. 

3) Our factory can also manufacture various sizes of NdFeB magnet, according to the customer's specification

4) Machining Process:

    Diameter<6mm--- Grinding block into rod shape--Cutting-Plating

    Diameter>6mm---Grinding cylinder to accurate size--cutting-plating
