Neodymium-iron-boron ring magnet (NdFeB)
Roco magnetics

As the third generation rare earth magnets, NdFeB ( Neodymium+Iron+Boron) provides the highest maximum energy product among permanent magnets. It was exploited in the 1980s and is called “The king of magnet” for its highest magnetic energy product.

They are manufactured from rare earth raw materials and priced to be the most cost-effective high-energy magnets on the market.

● A sintered material that offers superior mechanical properties.
● Highest energy materials.
● Operating temperature range: from +80℃ to 200℃.
● Excellent demagnetization resistance capability.
● Neodymium magnets are usually provided with a coating to protect
