Product Overview

Samarium cobalt magnets are strong permanent magnets made from samarium, cobalt, and other minor elements. They are renowned for their high magnetic strength and excellent temperature stability. While samarium cobalt magnets are generally weaker than neodymium magnets at room temperature, they can still operate reliably at extreme temperatures when neodymium magnets cease to function. SmCo magnets exhibit strong corrosion and oxidation resistance, often eliminating the need for coatings. Due to their sintered manufacturing process, samarium cobalt magnets are very brittle and may have internal cracks.
