Magnetic steel generally refers to aluminum-nickel-cobalt alloy. Magnetic steel is synthesized from several hard and strong metals, such as iron and aluminum, nickel, cobalt, etc., and sometimes copper, niobium, and tantalum. It is used to make super-hard permanent magnet alloys. The following is a brief introduction of permanent magnet materials for you, hoping to bring you a certain degree of help. Permanent magnet material A material with a wide hysteresis loop, high coercive force, and high remanence. It can maintain constant magnetic properties once magnetized. Also called hard magnetic material. In practice, permanent magnetic materials work in the second quadrant demagnetization section of deep magnetic saturation and hysteresis loops after magnetization. Commonly used permanent magnet materials are divided into aluminum-nickel-cobalt-based permanent magnet alloys, iron-chromium-cobalt-based permanent magnet alloys, permanent ferrites, rare earth permanent magnet materials, and composite permanent magnet materials. ①AlNiCo permanent magnet alloy. It contains iron, nickel, and aluminum as main components, and also contains copper, cobalt, and titanium. With high remanence and low temperature coefficient, the magnetic stability is stable. There are two types of casting alloys and powder sintered alloys. In the 1930s and 1960s, it was widely used, and now it is mostly used for instrumentation.
The industry manufactures magnetoelectric instruments, flow meters, micro special motors, relays, etc. ② The iron-chromium-cobalt permanent magnet alloy contains iron, chromium, and cobalt as the main components, and also contains molybdenum and a small amount of titanium and silicon elements. The iron-chromium-cobalt permanent magnet alloy has strong workability, can be cold-thermoplastically deformed, and has magnetic similarity to the aluminum-nickel-cobalt permanent magnet alloy, and can improve magnetic properties through plastic deformation and heat treatment. Used to make a variety of small magnet components with small cross sections and complex shapes. ③ permanent ferrite. There are mainly barium ferrite and strontium ferrite, which have high resistivity and large coercive force, and can be effectively used in atmospheric gap magnetic circuits, especially suitable for Permanent magnets of small generators and motors. Permanent ferrite does not contain precious metals such as nickel and cobalt. It has abundant raw materials, simple processes, and low cost. It can replace magnetic separators, magnetic bearings, speakers, and microwave devices instead of aluminum-nickel-cobalt permanent magnets. However, its maximum magnetic energy product is low, its temperature stability is poor, its texture is brittle and fragile, and it is not resistant to shock and vibration. It is not suitable for measuring instruments and magnetic devices with precise requirements. ④ Rare earth permanent magnet materials. Mainly rare earth cobalt permanent magnet materials and neodymium iron boron permanent magnet materials. before
It is an intermetallic compound formed by rare earth elements cerium, praseodymium, lanthanum, neodymium and cobalt, and its magnetic energy product can reach 150 times that of carbon steel, 3 to 5 times that of aluminum-nickel-cobalt permanent magnet materials, and 8 to 8 times that of ferrites. 10 times, low temperature coefficient, stable magnetism, coercive force up to 800 kA / m. Mainly used in low-speed torque motors, starter motors, sensors, magnetic bearings and other magnetic systems.
