Ndfeb rare-earth magnets are often called "permanent magnet materials", so how long can the magnetism of our permanent magnet last? If stored normally, permanent magnets should not lose more than 1% of their field strength in 100 years. PTMS Magnetic Separator is used, but there are some conditions that can cause your magnet to lose its magnetism: temperature, for example.
The environment around the magnet is more stable than the rated NdFeb material, and the heat will significantly reduce the Magnetic properties of PTMS Magnetic Separator permanent magnet. The maximum stability of standard Ndfeb rare earth materials is 80 degrees Celsius. High temperature resistant neodymium magnets are approximately 140 °C. The maximum operating temperature is over 540 °C for aluminum-nickel-cobalt magnets, and about 300 °C for samarium cobalt magnets and ferrites.
Due to the material characteristics of PTMS Magnetic Separator permanent magnet materials, the whole is fragile and easy to break when impacted by external forces. The magnetism of NdFeb permanent magnet damaged by external force will be reduced. Welding around permanent magnets can also cause a decrease in magnetic properties, which can be caused by heat or electric currents generated during welding.
