Injection magnetic ring price is widely used, all fields will also involve magnets, in some use will also encounter high temperature or bottom temperature in the work. For example, in some industrial production, commercial services in the use of high temperature magnet work is often, so what material magnet has a better heat resistance properties, and what magnet resistance to low temperature properties more outstanding?

There is no very perfect plastic magnetic ring price naturally there is no perfect objects, magnets are not excluded. In the permanent magnet is divided into many kinds of material magnet, there are super strong magnet Ndfeb magnet, ferrite magnet, aluminum nickel cobalt magnet, samarium cobalt magnet, etc.. To put it bluntly, ferrite plastic magnetic price is in the condition of continuous high temperature can maintain magnetic will not change, and can bear the natural environment of high temperature work. But not all magnets can bear a certain temperature, such as the super-strong magnet Ndfeb magnet can bear the working temperature is 230°C, and samarium cobalt magnet working temperature is 350°C Curie temperature can achieve 850°C, aluminum nickel cobalt magnet working temperature can achieve 550°C. The feigned temperature of ferrite magnet is 250°C. If it exceeds the working temperature that this type of magnet can bear, the magnetic band will be demagnetized, and if it exceeds 1500°C, it will melt. After talking about high temperature, the magnet for lower temperature tolerance, such as iron oxygen heat resistance is very very good, but the ability to work at low temperature is not good. The demagnetization of ferrite gradually occurs when the ferrite reaches -40°C at ultra-low temperature. Therefore, ferrite is not likely to occur on outdoor products in northern regions. But ndfeb magnets can work normally at temperatures as low as -130°C. I heard it was due to a shift in magnetic direction, which reduced the characteristics by about 15%.
