WebAlnico magnets have the benefit of having the lowest temperature coefficient, or temperature stability of all of the permanent magnet materials. Plus, they can be calibrated and have high residual induction.Before the development of rare earth magnets in the 1970’s, alnico was the strongest type of permanent magnet. WebAmong commercial magnet materials, the rare earth magnets made from neodymium iron boron are the most powerful in the marketplace. Available in both sintered and bonded forms, this class of rare earth material possesses the highest Br, high BHmax (approximately 10–53 MGOe), and relatively high Hc. Other key characteristics include:
