Alliance N-45 Neodymium Iron Boron Magnetic Material
Categories:	Metal; Electronic/Magnetic Alloy; Ferrous Metal
Material Notes:	Neodymium magnets (NdFeB or Neo), are the most commonly used magnet materials for high tech motors and sensors. They are popular due to their high magnetic strength and resistance to demagnetization. They do not have the high temperature resistance of other magnet materials, however they can be used in applications with maximum operating temperatures of 220°C. Because of a high iron content, they will corrode over time if not plated or coated. As with all magnet materials, NdFeB should never be used as a structural element in an application.
Key Words:	NdFeB; Neo, Magnet, Magnets
