China Neodymium And Ferrite Magnets Manufacturer & Supplier 
Whether it is rare earth neodymium strong magnets or today's ferrite magnets, although they are called permanent magnets, they are also affected by temperature. What is the working temperature resistance range of ferrite? Let me introduce you to you.
What are the positive and negative degrees of temperature resistance of ferrite magnets? The following picture shows a rectangular ferrite permanent magnet.
The temperature resistance range of hard ferrite magnets is -40 ℃~250 ℃.
When reaching -20 ° C (-4 ° F) or lower, the coercive force (Hci) drops to a level that may cause the magnet to begin demagnetization (depending on shape and application)
In special circumstances, it can sometimes reach+300 ° C (572 ° F).
The above is the introduction by courage, a supplier of ferrite permanent magnets, about the positive and negative degrees of temperature resistance of ferrite magnets. Our company can provide various shapes of ferrite magnets, with a complete range of sizes. If you have any questions or inquiries about ferrite magnets or prices, you can contact customer service on the website to answer them.
