The magnets are composed of neodymium, iron, boron and a few transition metals. Sintered ndfeb magnets are the most powerful permanent magnets available today. It has a combination of very high remanence and coercivity, and comes with a wide range of grades, sizes and shapes such as rings, blocks, discs and segments. With its excellent magnetic characteristics and abundant raw material, ndfeb magnet offers more flexibility in designing of new or replace the traditional magnet materials such as ferrite, alnico and sm-co to achieve high efficiency, low cost and more compact devices. Ndfeb magnet is highly susceptible to corrosion and coating is always necessary. Frequently they are plated in nickel, zinc, tin and epoxy resin.

Attributes of Samarium Cobalt • High resistance to demagnetization • High energy (magnetic strength is strong for its size) • Good temperature stability • Expensive material (cobalt is market price sensitive) Applications of Samarium Cobalt Computer disc drives, sensors, traveling wave tubes, linear actuators, satellite systems, motors where temporary stability is vital. Magnetizing and Handling Samarium Cobalt magnets are very brittle and very strong magnetically. Therefore, it is crucial to handle these magnets with extreme care to avoid personal injury and damage to the magnets. Fingers can be severely pinched between attracting magnets. Magnets can chip if allowed to “jump at” an attracting object. It is highly recommended that when constructing rare earth magnetic assemblies, they be magnetized after assembly. Samarium Cobalt Machining Since Samarium Cobalt magnet material is prone to chipping and cracking, it does not lend itself to conventional machining methods. It can, however, be abrasively ground, but only with the use of liberal amounts of coolant. The coolant minimizes heat fracturing and the risk of fires caused by oxidized grinding dust.
