What are samarium cobalt magnets used for?
Samarium cobalt magnets, because of their characteristics are most commonly used in applications which require high operating temperatures such as generators, pump couplings, sensors, motors, marine applications and in the automotive, aerospace, military and food and manufacturing industries.
Are samarium cobalt magnets strong?
A samarium–cobalt (SmCo) magnet, a type of rare-earth magnet, is a strong permanent magnet made of two basic elements samarium and cobalt. Samarium–cobalt magnets are generally ranked similarly in strength to neodymium magnets, but have higher temperature ratings and higher coercivity.
Are samarium cobalt magnets stronger than neodymium?
Although not as strong as a neodymium magnet – samarium cobalt magnets typically have an BHmax of about 26 – these magnets have the advantage of being able to withstand much higher temperatures than neodymium magnets.
Is samarium cobalt a permanent magnet?
Samarium Cobalt (SmCo) magnets are strong permanent magnets with exceptional magnetic properties. They offer excellent temperature stability and a high resistance to corrosion or demagnetization.
Does the human body use samarium?
According to researchers, samarium speeds up metabolism. In the human body, the metal is found in the bloodstream, kidneys, and liver. Exposure may cause eye and skin irritation because the salts and compounds are found to be moderately to highly toxic. The metal has been found in some plants and animals as well.
Is neodymium same as rare earth?
What are Rare Earth Magnets? The term ‘rare earth’ can be misleading as rare earth metals are relatively abundant in the Earth’s crust. Neodymium magnets, the stronger of the two, are composed of alloys primarily of neodymium, iron, and boron. These magnets tend to be brittle and are vulnerable to corrosion.
Where is samarium naturally found?
Samarium is the fifth most abundant of the rare elements and is almost four times as common as tin. It is never found free in nature, but in contained in many minerals, including monazite, bastnasite and samarskite. Samarium containing ores are found in USA, China, Brazil, India, Australia and Sri Lanka.
Samarium Cobalt rare earth magnets are often used in high temperature applications needing high magnetic performance and where magnetic stability over a wide range of temperatures is important.
Why choose EEC for samarium cobalt?
As the only remaining U.S. producer of samarium cobalt, EEC also provides DFAR compliant materials. EEC is certified to AS9100D and ISO 9001:2015 with the systems in place to satisfy DPAS rated (DX or DO) requirements. As a producer of permanent magnet materials, EEC has a deep understanding of the science behind the materials.
What is the maximum operating temperature of a cobalt magnet?
Maximum operating temperatures for Samarium Cobalt magnets are between 250 and 550 °C; Curie temperatures range from 700 to 800 °C. (top) Common Applications for Samarium Cobalt Magnets Samarium Cobalt (SmCo) magnets have excellent temperature stability while maintaining their magnetic properties in extreme temperature conditions.
What are SmCo Disc magnets?
Samarium cobalt (SmCo) disc magnets are strong permanent magnets that perform well in high or very low temperature environments. Part of the rare earth magnet family, SmCo magnets have a high resistance to corrosion or demagnetization.
