Neodymium Magnets

Neodymium Iron Boron Magnets are made from rare earth raw materials and priced to be the most cost-effective high -energy magnets on the market.

Our standard NdFeB is rated to +80 deg C. We offer the whole range of Neodymium Iron Boron magnets, with Maximum Energy Product (BHmax) ratings from 33 MGOe to 52 MGOe (N33 to N52) and with a maximum operating temperature rating ranging from +80 deg C to +200 deg C (Grade N to EH)

Neodymium magnets are usually provided with a coating to protect against oxidizing.
Galvanic processed are used for metallic coating, like nickel, tin or zinc. Nickel-copper-nickel coatings or double coating are possible on request.

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

The Neodymium magnets are also known as Neo magnets, Neodymium Iron Boron magnets, Neodymium-Iron-Boron magnets, 
NdFeB magnets, NIB magnets, Super Strength magnets and Rare Earth magnets

  • Disc Magnets

    NdFeB (neodymium Iron Boron) magnet is the third generation of rare-earth permanent magnet, named "king magnet" for its great performance and competitive price. It's widely used in modern industry and electronic technology. Disc Size of Neodymium Magnets. Widely used in toy , sensor, relay and switch ! The following items are the relative products of the NdFeB Disc Magnets, you can quickly find the NdFeB Disc Magnets through the list. Almost all disc magnets have their north and south poles on the flat sphere surfaces (axial magnetization). The few exceptions that are diametrically...

  • Rod Magnets

    Rod Size of Neodymium Magnets. Widely used in toy, sensor, relay and switch ! The following items are the relative products of the NdFeB Rod Magnets,you can quickly find the NdFeB Rod Magnets through the list.  All rod magnets have their north and south poles on the even circular surfaces (axial magnetisation). The few exceptions that are diametrically magnetised are especially marked. Specifications 1) High and Stable Performance 2) Perfect Consistence 3) Good Price 4) Fast DeliveryFeature 1. Stable performance  2. Excellent corrosion resistance  3. High working te...

  • Ring Magnets

    Neodymium ring magnets are being designed into a new generation of motors, generators, hydraulic cylinders, pumps & sensors. They also remain popular in high end loud speakers & high intensity separators. Specifications: 1. Excellent temperature stability 2. Strong corrosion resistance 3. High residual induction 4. Relatively high energies characterize5. Standard tolerance Advantages: 1. Good Quality: Our NdFeB permanent magnets has highly consistent magnetic property and high temperature resistance, particularly suitable for all kinds of motors, electrical machinery, electronic...

  • Block Magnets

    Block Size of Neodymium Magnets. Widely used in Magnetic Separator, relay and switch !The following items are the relative products of the NdFeB Block Magnets, you can quickly find the NdFeB Block Magnets through the list.Block magnets can magnetized through every surfaces ! Most have north and south poles on the two largest surfaces.Product specifications:1. Neodymium Block Magnets with different grades of: N35,N38,N40,N42,N45,N48,N50,N52(M,H,SH,UH,EH) etc.2. Working temperature for Neodymium Block Magnets:from 80 centigrades to 230 centigrades.3.Can be magnetized according to the requirement...

  • Segment Magnets

    Neodymium Pot Magnets. Widely used in assorb ! The following items are the relative products of the NdFeB Pot Magnets, you can quickly find the NdFeB Pot Magnets through the list. This neodymium ring magnet in a steel pot is countersunk. It can be fastened with a countersunk screw. The steel pot substantially increases the holding power of the magnet, but requires full contact with the opposing part, e.g. a steel plate. Magnets in steel pots don't have much effect into the distance, i.e. they are not suitable to attract a metal item from a distance, but they are very well suited to hold on t...

  • Sphere Magnets

    Sphere Size of Neodymium Magnets. Widely used in toy ! The following items are the relative products of the Neodymium Sphere Magnets, you can quickly find the NdFeB Sphere Magnets through the list. Please note: Due to the dangers of swallowing magnets, BKMAG are not suitable as toys for small children and should be kept out of their reach! If suitable for ages +12 only !Sphere Magnets Specifications 1.Precise dimension 2.Various shape 3.Stable performance 4.Good corrosion resistance 5.Easy to mass production Our Advantages 1. Strict quality control: rich experienced QC team guarantees...

  • Large Disc

    Our strongest disc magnet. Given its holding power of 50 kg, one must naturally take extra care when handling these. With a diameter of 4,5-7 cm,  this magnet hardly looks suspicious.  Ah, but looks can be deceiving! Once in contact with a thick piece of metal, this magnet is nearly impossible to remove again. Paperclips and nails - even at a 8 cm distance - cannot withstand the pull!NdFeB ,N35, D45*15 mm, Ni Coating                NdFeB ,N35, D45*25 mm, Ni Coating                 NdFeB ,N35, D45*3...
