SmCo5

SmCo5 is a samarium-cobalt permanent magnet alloy that belongs to the rare-earth magnet family, valued for its exceptional magnetic strength and high-temperature stability. It is widely used in aerospace, defense, and industrial applications where reliable performance in extreme thermal environments is critical, such as aircraft engines, satellite systems, and high-speed motors. SmCo5 offers superior performance compared to ferrite magnets and was historically important before neodymium magnets became dominant; it remains the preferred choice when operating temperatures exceed the capabilities of NdFeB magnets or when magnetic field stability over decades is essential.
