? Any substance in the external magnetic field can be magnetized, rare earth permanent magnets, but according to the degree of magnetization and exhibits characteristics, material can be roughly divided into three categories: paramagnetic, diamagnetic and ferromagnetic. Paramagnetic and diamagnetic materials are commonly called weak magnetic material, and a ferromagnetic material is called a ferromagnetic material, commonly referred to as a magnetic material refers to a ferromagnetic material. According to different demagnetization difficulty after magnetization of the magnetic material is easy to be called a soft magnetic material, it will not be easy to demagnetization called permanent magnetic material. Soft magnetic material remanence weak? Specializes in producing rare earth permanent magnets, and easily demagnetized. Applications that require repetitive magnetization places, such as recorder heads, in computer memory components, switching power supplies, transformers and alternators, solenoids and various high-frequency components of the core and the like. Yong-strong magnetic remanence, and difficult demagnetization, made for permanent magnet? Rare earth permanent magnet market price, in permanent magnet motors, magnetic separator, speakers, magnetic-electric instruments and other devices. Ferrite materials, etc. Due to demand for cars and computers with high-grade magnets increases, the proportion of high-grade ferrite China will increase rapidly. Expected Tenth Five-Year period Y30H-1 series of high-end products will be increasing the proportion of about 40% in 2000 over 2005, 60% (about 126,000 tons), production Y30H-2 brand above series of high-end products can reach 10 about% (about 21,300 tons), the proportion of total exports increased to more than 50%. ? Rare earth permanent magnet factory outlets, the new magnetic Tong Xin,? Rare earth 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.
