The advantages of NdFeB are high cost performance and good mechanical properties. The disadvantages are low Curie temperature, poor temperature characteristics and easy pulverization and corrosion. It must be improved by adjusting its chemical composition and adopting surface treatment to meet the requirements of practical application.
Recently, the price of rare earths has continued to rise, especially medium and heavy rare earths. Since the beginning of this year, the price of NdFeB has risen sharply, about six times from the beginning of the year to July, with a considerable increase. The essence of NdFeB pricing is that the rise of rare earth prices is a national strategy. It is normal for some downstream low value-added application industries to complain and quit, but they will eventually get used to the current price and should look at the future rare earth price.
The price of NdFeB has risen rapidly in the last two or three months. The fan is made of high-end NdFeB, and the price has increased from more than 200,000 yuan per ton to 2 million yuan per ton.
