Industrial Magnetics Large Neodymium Magnets

Magnet Display
Neodymium-Iron-Boron (NdFeB) magnets are composed of neodymium, iron, boron, and a few transition metals. These kinds of permanent magnets are extremely strong and can be produced in different shapes and sizes (ie. arcs, blocks, discs, rings).

It has higher unit magnetic properties than other magnet and assures you of smaller size and lighter weight in designing devices.

Grade 
cover N35-N52, N30M-N50M, N30H-N48H, N30SH-N45SH, N28UH-N40UH, N28EH-N38EH. 

Size and Shape
D3--D280mm(round)Cylindrical,
Ring, Square, Holed Square, Watt, Arch, or Customized. 

Coating
Nickel, Nickel copper-nickel, Zinc, Golden, Black epoxy, Grey epoxy, Phosphating, and so on. 
n40 neodymium magnets
Direction of magnetization
Through the thickness or through the diameter.

FAQ
Q: How long is your lead time?
A: Generally it is 5-10 days if the goods or materials are in stock. or it is 20-25days for new production, it is according to the order quantity.

Q: What is your MOQ?
A: We have no strict MOQ, if we can do, we will try our best to cooperate; if any questions as small quantity, we will be open to communicate with our customers for a better solution.

Q: What are your terms of payment?
A: Payment<=10,000/sd,100% in advance, paymcnt>=10,000usd,30%t/t in advance, balance before shipment.

Q: Will magnets lose their power over time?
A: Modern magnet materials do lose a very small fraction of their magnetism over time. for samarium cobalt materials, for example, this has been shown to be less than 1% over a period of ten years.

Q: What might affect the strength of a magnet?
A: The factors can affect a magnet's strength: heat radiation strong electrical currents in close proximity to the magnets other magnets in close proximity to the magnet(Neodymium magnets will corrode in high humidity environments unless they have a protective coat-ing-) shock and vibration do not affect modern magnet materials unless sufficient to physically damage the material.

Q: Can a magnet that has lost its magnetism be re-magnetized
A: Provided that the material has not been damaged by extreme heat. the magnet can be re-magnetized back to its original strength.

Q: Can I make a magnet that I already have any stronger?
A: Once a magnet is fully magnetized, it cannot be made any stronger-it is"saturated." in that sense, magnets are like buckets of water; once they are full. they can't get any "fuller."

Q: Can you supply magnets with one pole on the outside and one on the inside?
A: Ring magnets can be magnetized this way and they are referred to as radially magnetized.
