Introduction: What Are Samarium Cobalt (SmCo) Block Magnets?
Samarium Cobalt (SmCo) block magnets are a type of rare-earth magnet made from samarium (Sm) and cobalt (Co). These magnets are prized for their exceptional strength, high resistance to demagnetization, and ability to retain their magnetic properties even at elevated temperatures. With high magnetic flux density, low temperature coefficients, and robust resistance to oxidation, SmCo magnets are critical components in a wide range of industrial applications such as electric motors, sensors, and aerospace technology.
In 2023, the global Samarium Cobalt (SmCo) block magnets market was valued at approximately USD 420 million. This market is anticipated to steadily expand, with projections indicating a rise to USD 560.17 million by 2030, reflecting a compound annual growth rate (CAGR) of 4.20% from 2023 to 2030. This steady market growth can be attributed to increasing demand for high-performance magnetic materials across industries like automotive, defense, renewable energy, and consumer electronics.
