About NdFeB Magnets
NdFeB magnets are the strongest permanent magnets, mainly made from neodymium, iron, and boron, with additional elements like cobalt and dysprosium to enhance strength and stability. They are vital in high-performance electronics, electric vehicles, and wind turbines.
Types
They are sintered, bonded, or hot-pressed, with sintered offering the best magnetic performance and bonded providing design flexibility.
Key Properties
High magnetic strength and resistance to demagnetization, but require protective coatings due to relatively weak mechanical strength.
Importance for India
The pilot plant improves India’s self-reliance in critical materials, supporting clean energy transitions and defense technologies.
