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 high temperature permanent magnets Which is good, people mainly use carbon steel, tungsten steel, chrome steel and cobalt permanent magnet material for steel. The late 1930s the permanent magnet temperature Which promotions, alnico magnet developed, to make large-scale application of the magnet is possible. Which fifties affordable high temperature permanent magnets, there barium ferrite magnet, a permanent magnet not only reduces the cost, scope of application of permanent magnet materials in turn widened to high frequency fields. Ferrite Ferrite currently the most widely used, and materials can be divided according to purpose: MnZn power ferrite materials, communications and electromagnetic compatibility (EMC) with high permeability Mn-Zn ferrite material, deflection coil Mn-Zn ferrite material, the RF broadband and electronic interference (EMI) suppression of nickel zinc ferrite material and other four categories. Material further to the high-frequency, high permeability and low loss development, which is two high and one low direction. Device development to small, surface mount chip and direction. _ Where high-temperature high-temperature permanent magnet permanent magnet magnetic Xin Tong _ new offer by the Dongguan City Tong Xin magnetic Limited. Dongguan City, Tong Xin magnetic Limited (www.dgxtxmagnet.com/) strong, credible, magnetic materials in Dongguan, Guangdong and other industries has accumulated a large number of loyal customers.
