In the vast landscape of industrial magnets, SmCo magnets were the first rare-earth-based magnets to be commercialized. These magnets are composed of a samarium and cobalt alloy, available in two variants with different amounts of iron, hafnium, copper, and other elements added. This class of permanent magnets offers very interesting magnetic performance, up to 1.15 Tesla and an energy product up to 240 kJ/m3. Let’s take a detailed look at what SmCo magnets are, their distinctive characteristics, and the applications they are used in.
Key Characteristics
Thanks to their chemical composition and crystalline structure, SmCo magnets boast a series of properties that make them ideal for « demanding » industrial applications. Their exceptional resistance to corrosion and high temperatures makes them suitable for use in critical environments where other types of magnets might lose effectiveness. Additionally, SmCo magnets are known for their ability to maintain consistent performance over time.
Industrial Applications
SmCo magnets are widely used in a variety of industrial sectors requiring reliable performance under extreme conditions. In the aerospace and military sectors, they are used in control and actuation systems for aircraft and satellites. In the medical field, they are employed in Magnetic Resonance Imaging (MRI) devices thanks to their ability to maintain their magnetic power even in the presence of intense magnetic fields. Other applications include high-performance electric motors, precision sensors, and actuators for industrial robotics.
Resistance to High Temperatures and Corrosion
One of the distinctive characteristics of SmCo magnets is their exceptional resistance to high temperatures and corrosion. This property makes them particularly suitable for applications in harsh environments, such as the oil industry, where they are exposed to high temperatures and corrosive chemicals. Additionally, their resistance to demagnetization makes them a reliable choice for devices operating in environments with strong magnetic fields or temperature variations.
