Product Overview

Sintered Neodymium Magnets are permanent rare earth magnets made from neodymium, iron and boron that are sintered together to form strong, durable magnets. With high coercivity and strong magnetic properties, these magnets are ideal for applications including new energy cars, wind power generation, servo motors, and traction motors.
