Neodymium Iron Boron Magnets
Neodymium iron boron (NdFeB), or “neo” magnets offer the highest energy product of any material today and are available in a wide range of shapes, sizes and grades including GBD. Neo magnets can be found in a variety of applications including high performance motors, brushless DC motors, magnetic separation, magnetic resonance imaging, sensors and loudspeakers.Learn More
Sintered or Cast Alnico delivers impressive flux density at an economical price. It boasts the lowest reversible temperature coefficient of any standard commercial magnet material (0.02% per degree centigrade) allowing for excellent stability over a wide temperature range. Alnico is also inherently corrosion resistant.Learn More
Injection Molded Magnets
Injection molded magnets are essentially fully dense magnetic powders blended with a variety of polymer base materials. Depending on the combination of magnetic material and polymer selected, a wide range of final material properties are possible.Learn More
L Type Laminated Magnets
High efficiency demands the best materials, and the Arnold L Type laminated rare earth magnets are proven to reduce eddy current losses in high efficiency motors. Less eddy current loss means less heat and less waste. Designers in the aerospace, automotive, motorsport, and industrial markets are turning to laminated rare earth magnets.Learn More
