The Curie temperatures of samarium cobalt magnets are between 1,100°F to 1,300°F (600°C to 710°C), with a favorable working range between 500°F to 1,000°F (250°C to 550°C). Neodymium Iron Boron magnets are the strongest permanent magnets available at room temperature and up to about 180 degrees C –measured by their magnetic Remanence (Br). They are metallic in appearance, have a high energy as well as a high resistance to demagnetization. They were developed in the early 1960s based on work done by Karl Strnat and Alden Ray at Wright-Patterson Air Force Base and the University of Dayton, respectively.In particular, Strnat and Ray developed the first formulation of SmCo 5. Expensive material (cobalt is market price sensitive) Applications of SmCo Magnets - Computer disc drives, sensors, travelling wave tubes, linear actuators, satellite systems, motors where temporary stability is vital. Here we will introduce samarium cobalt magnets for sale that output high magnetic force, but also can work under 250-350°C. SmCo flux output varies much less with respect to temperature, meaning the device performance can truly be optimized. This chapter reviews the development of SmCo-type magnets over the last 40 years. While stronger rare earth permanent magnets have been discovered and made commercially available samarium cobalt is still the first choice magnet for adverse or high temperature environments.
