permanent magnetic material
permanent magnetic material
Has a wide hysteresis loop, high coercivity and high remanence, which can be magnetized by a constant magnetic materials. Known as hard magnetic materials. Practical, in-depth work of permanent magnet material and magnetic saturation magnetization hysteresis loop after the second quadrant of the demagnetization. Permanent magnet materials commonly used aluminum into permanent magnet alloy of nickel and cobalt, iron magnetic cobalt-chromium alloy, hard ferrite, rare earth permanent magnet materials and composite permanent magnet materials.
¢Ù AlNiCo of permanent magnet alloy. Iron, nickel, aluminum elements as the main component, but also contains copper, cobalt, titanium and other elements. Remanence with high and low temperature coefficient, magnetic stability. - Casting alloys and alloy powder sintering two. 20th Century 30 ~ 60 more in the application, is used for industrial instrumentation in the manufacture of magnetic-electric instruments, flow meters, micro motors, relays, etc..
¢Ú FeCrCo of permanent magnet alloy. Iron, chromium, cobalt element for the major components, also contain a small amount of molybdenum and titanium, silicon. Its processing performance and thermoplastic can be cold deformation, and the magnetic properties similar to the magnetic nickel and cobalt aluminum alloy, and through the plastic deformation and heat treatment can improve the magnetic properties. Section used in the manufacture of various small, complex-shaped components of small magnets.
