Powerful samarium cobalt block magnets pack high magnetic strength into a compact package—all while offering superior resistance to heat and corrosion. Samarium cobalt magnets are capable of performing at temperatures of up to 300°C, or 572°F. Due to their high resistance to corrosion, they are a great pick for highly corrosive environments, such as open ocean settings where magnets are exposed to saltwater. In comparison to ceramic and alnico magnets, samarium cobalt magnets provide superior strength in a compact package. Samarium cobalt magnets are commonly used in automotive applications, commercial and defense aircraft applications, industrial settings, and electronics.
