Common magnetic Hengdian Kim factory ----- soft magnetic materials magnetic energy parameters saturation magnetization Bs: its size depends on the composition of the material, it corresponds to the physical state of the material inside the magnetization vector is aligned. Residual magnetic flux density Br: is the characteristic parameter of the hysteresis loop, H back to 0 when B value. Squareness ratio: Br / Bs coercive force Hc: the amount of material is magnetized degree of difficulty, depending on the material composition and defects (impurities, stress, etc.). Permeability μ: is the ratio of the hysteresis loop at any point in the corresponding B and H, and closely related to the device operation status. Hengdian Kim factory ---- NdFeB magnetic material by those who? The main raw material NdFeB rare earth permanent magnets are neodymium, iron and non-metallic element boron (sometimes with the addition of aluminum, cobalt, praseodymium, dysprosium, terbium, gallium, etc.) industrial magnetic Which is good, by the general formula: RE2TM14B (RE = Nd, Pr local industrial magnetic, Dy TM = Fe Industrial magnetic, Co) NdFeB permanent magnet materials are Nd2Fe14B ternary compound as the substrate, the composition should be similar to the compounds of formula Nd2Fe14B. But exactly as Nd2Fe14B composition ratio, the magnets can be very low, or even non-magnetic. The actual content of which is neodymium and boron magnet neodymium and boron content than Nd2Fe14B compound is large (that formed the Nd-rich phase and boron-rich phase) in order to obtain better magnetic properties. Matrix Nd2Fe14 phase this phase is the main phase of industrial magnet magnetic manufacturer, its volume (after Lianwan ingot has basically fixed) determines the magnetic remanence (Br), the maximum energy product ((BH) m), and When forming the magnetic field orientation is to realize that it is arranged so that the distribution of the molecular structure of the easy axis (C) are ordered along the alignment direction, resulting in higher magnetic properties. Industrial magnetic plant, the large magnetic plant styles (certified), Hubei magnetic Hengdian gold by large magnetic plant. Hengdian Dongyang City, Kim Dae-magnetic Factory (www.jjdct.cn) is an industry leader in Jinhua, Zhejiang, electronics, electrical products manufacturing equipment, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs . In the Kim Dae-magnetic plant leadership with the staff warmly welcome all inquiries negotiations to create a large magnetic plant gold better future.
