Temperature Considerations for Ceramic Ferrite Magnets
Ceramic magnets can be used at fairly high temperatures, although their magnetic properties drop with temperature. At 175°C (350° F), approximately 75% of their room temperature magnetic properties are retained.
We are a magnet factory in China, and we have a large number of round ferrite sizes available. Welcome to tell us the specifications you need by email or inquiry.
