Rare Earth Magnets (Samarium Cobalt & Neodymium)

Collectively known as Rare Earth magnets, Samarium Cobalt (SmCo) and Neodymium Iron Boron (NdFeB) magnets are alloys of the Lanthanide group of elements. Rare Earth magnets are the most advanced commercialized permanent magnet materials today. SmCo magnets are available in a number of different grades that span a wide range of properties and application requirements. SmCo magnets are brittle and machining operations should be performed prior to magnetization, using diamond tools. We are equipped to fabricate these materials to blueprint specifications.

Samarium Cobalt

Attributes of Samarium Cobalt Material Applications of Samarium Cobalt Magnets

Computer disc drives High resistance to demagnetization

High energy (magnetic strength is strong for its size)

Good temperature stability

Expensive material (cobalt is market price sensitive)

Computer rigid disc drives, printers and speakers

Neodymium Magnets

Neodymium magnets (Nd-Fe-B) are composed of neodymium, iron, boron and a few transition metals. These magnets are extremely strong for their small size, metallic in appearance and found in simple shapes such as rings, blocks and discs.

Attributes of Neodymium MaGNETS

Very high resistance to demagnetization

High energy for size

Good in ambient temperature

Low working temperature for heat applications, but higher levels of heat resistance materials are being introduced periodically
