Recoma®
18Pages

Since the beginning of rare earth magnet production in the early 1970's, Recoma® has been a synonym for high quality SmCo materials. The combination of excellent magnetic properties with superior temperature and corrosion stability has made these materials the standard for applications in demanding environments. Offering the best magnetic properties at elevated temperatures, SmCo magnets are widely used in the chemical and aerospace industries, as well as in many automotive "under the hood" applications. Owing to their superior corrosion stability, SmCo magnets can in most cases be used without protective coating. And since they show little or no surface degradation during machining, SmCo are the ideal materials for rare earth micromagnets. There are two families of SmCo materials. The Sm2Co17 magnets show the highest magnetic performance at elevated temperatures. Magnets based on SmCo5 offer easy magnetizing in moderate fields and the best corrosion resistance of all rare earth magnets. The most common Recoma materials are presented in detail on the following pages. In addition to these main grades, materials with rather unique properties are available: Materials where the temperature coefficient of magnetization can be adjusted to a preferred value (including zero), or materials for highest operating temperatures up to 500°C and beyond. These materials are usually customized to the requirements of the individual customer. Please contact us for a solution to your application needs. © 2014 Arnold Magnetic Technologies Corporation

Maximum Operating Summary of main grades of SmCo5 and Sm2Co17 1) A = Axial; T = Transverse or Isostatic 2) Magnetizing Field - Values are dependent on size, shape and characteristics of the magnetizing pulse 3) Maximum Operating Temperature - In the presence of strong demagnetizing fields or if the magnets operate on a low loadline, the maximum temperature may be considerably lower. High Temperature and Temperature Stabilized grades are also available. Please consult your Arnold representative to learn more about these products.
