OEM products
This is neodymium magnet, it is the third generation rare earth permanent magnet. And it is the most powerful and strongest magnet in World at present. No other magnet is stronger than it at present.
1. The neodymium magnet mainly have two classification according the different production process, the sintered neodymium magnet and Bonded neodymium magnet.
2. The picture's product is the sintered neodymium magent, it was manufacutured by powder metallurgy.
it is the cylinder shape. the cylinder shape is one regular shape of sintered neodymium magnet.
3. This cylinder type magnets can be in large length, about 50mm long.
4. We can supply the rough, so that customers can cut the magnet into the length they need.
