What are Temperature Coefficients of Permanent Magnets? A new approach for calculating the temperature coefficients of magnetic parameters is proposed in order to more accurately describe high temperature characteristics of magnetic materials. Using this new approach, the "true" (or instantaneous) temperature coefficient of any magnetic parameter at a specific temperature can be determined and a [...]
Samarium Cobalt MATERIAL GRADES Known as Rare Earth magnets, Samarium Cobalt (SmCo) are alloys of the Lanthanide group of elements. SmCo magnets have been commercially available since the early 1970’s, first as a 1-5 Type alloy, and later with the introduction of the 2-17 type. Both alloys offer outstanding thermal stability and excellent corrosion resistance. [...]
SmCo Manufacturing Methods SmCo magnets are manufactured in the following forms: Sintered - fine SmCo powder is compacted in a die and then sintered, fusing the powder into a solid material. There are two forms of pressing - die pressing (which involves a hard die into which the powder is placed and then pressed), and [...]
Sintered SmCo General Information 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 [...]
