Application of Samarium Cobalt Magnets
Samarium cobalt magnets are applied in various industries around the world. Some of their properties make them well-suited for specific industries.
Sensors
Samarium cobalt magnets are used in sensors. These sensors are concerned with converting a magnetic field into electrical signals. The sensors are usually used in aerospace and automobiles.
Generators
Samarium cobalt magnets are used in generators. The samarium cobalt magnet provides the magnetic field for the generator. These generators are reliable and can be used in wind turbines.
Refrigerators
Samarium cobalt magnets are fast becoming popular in the refrigeration industry. Massachusetts Institute of Technology is currently researching how magnets can be used as refrigerants.
Nuclear Magnetic Resonance Spectrometer
Samarium cobalt magnets are also used in NMR spectrometers. In NMR spectrometers, magnets are used to investigate the spin of protons and neutrons. NMR spectrometers are used to study both the physical and chemical properties of organic compounds.
Medicine
Samarium cobalt magnets are used in medical equipment that require high temperatures for sterilization. This is because samarium cobalt magnets are stable under high temperatures. They are also used for medical implants.
Custom Made SmCo Magnets
We can manufacture any kind of SmCo Magnet on custom specifications. You can ask for Samarium Cobalt Magnets of any shape and size, with holes, threaded holes, pins, threaded rods, hooks or eyelets. Contact us by phone or email to get a quote and an estimated delivery time.
