OVERVIEW

Sintered NdFeB is the third generation of rare-earth permanent magnets, known as the “king of magnets” for its high coercivity, high energy product and excellent service performance.

We produce the full range of sintered NdFeB grades with the entire process under control, ensuring stable, consistent quality.
