With the development of society, the application of the magnets are increasingly being used, from high-tech products to the most simple packaging magnetic, currently the most widely used or NdFeB magnets and ferrite magnets. From the history of the magnet, the turn of the century, people mainly use carbon steel, tungsten steel, chrome steel and cobalt permanent magnet material for steel. The late 1930s, the successful development of aluminum-nickel-cobalt magnet, the magnet that makes large-scale applications possible. Fifties, there barium ferrite magnet, not only reduces the cost of a permanent magnet, in turn broaden the scope of application of permanent magnet materials to high-frequency fields. Magnet manufacturers: how to measure the magnetic properties of low? There are three main parameters: remanence Br (Residual Induction), high-temperature unit Gauss permanent magnets phone company, after the removal of a magnetic field from saturation, the residual magnetic flux density, representing the external magnetic field strength can offer; coercive force Hc (Coercive Force) high temperature permanent magnets Which unit Oersteds, is to put a magnet on a reverse magnetic field, when applied to a certain intensity of the magnetic field of the magnet will disappear, this ability to resist the applied magnetic field, said coercivity permanent magnet temperature, on behalf of the ability to measure the anti-demagnetization; energy product BHmax, units Gauss-Oersteds, is the magnetic field energy per unit volume of material generated by the magnet can store energy is how much of a physical quantity. High temperature permanent magnet business phone, the new Xin Tong magnetic, high temperature permanent magnet provided by the Dongguan City, Tong Xin magnetic Limited. Dongguan City, Tong Xin magnetic Limited (www.dgxtxmagnet.com/) Dongguan, Guangdong, magnetic leader, over the years, the company implement the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs. New Tong Xin magnetic leadership with the staff warmly welcome all inquiries to discuss, with new magnetic Xin Tong better future.
