Samarium Cobalt Rod Magnet
Samarium Cobalt (SmCo) rod magnets are a type of rare earth magnet made from an alloy of samarium and cobalt. They are known for their impressive magnetic properties and resistance to demagnetization. SmCo magnets typically come in two main series: SmCo5 and Sm2Co17, differing in their samarium to cobalt ratios and energy products. These magnets can operate effectively at higher temperatures, up to 350 degrees Celsius, making them ideal for applications in motors, sensors, and high-temperature environments. Additionally, they are resistant to corrosion, although they are more brittle and prone to cracking than other types of magnets like neodymium. SmCo rod magnets are cylindrical in shape, commonly used where a strong, compact permanent magnet is required. Despite their higher cost, their durability and thermal stability make them valuable in advanced and specialized technological applications.
