Samarium cobalt magnets, also known as samarium cobalt magnets, are alloys consisting of two basic elements, samarium and cobalt. SmCo magnets are a type of permanent magnet and rare earth magnets and are available in a variety of sizes and shapes. They are similar in strength to neodymium-earth magnets, but they have additional characteristics such as high heat resistance. Because of their advantages, samarium cobalt magnets have become much more popular. In fact, the samarium cobalt magnet industry was valued at $498 million in 2019, with China accounting for 71 percent of total consumption.
Properties of samarium cobalt magnets
Samarium cobalt magnets have a number of advantages that make them ideal for industrial applications. These advantages have contributed to the increasing popularity of samarium cobalt magnets. In fact, in some cases, samarium cobalt magnets may be more suitable than neodymium magnets.
Advantages of samarium cobalt magnets:
High heat resistance (up to 300°C)
Low temperature resistance (below absolute zero, -273°C)
Be price sensitive
High corrosion resistance
High resistance to demagnetization
High magnetic field strength
Although samarium cobalt magnets have many advantages, you should keep some considerations in mind when considering using samarium cobalt magnets for your commercial applications. SmCo magnets are fragile and work best in applications where direct impact is not required. These magnets are sensitive to market prices, but they are usually more expensive than some neodymium magnets. This is mainly due to the cost of producing cobalt and the fact that most magnets are manufactured overseas.
Application of samarium cobalt magnets
Due to the superior properties of samarium cobalt magnets, these magnets have a wide range of industrial applications. SmCo magnets are commonly used in applications where magnetic field strength and stability are critical at high temperatures. Some examples of industrial applications of samarium cobalt magnets include:
Motors, sensors, pump couplings, high temperature applications, food processing, prosthetics, generators.
