Telescopic light magnet

Samarium cobalt rare earth metals and strategic metals as a main component, iron, copper, zirconium, praseodymium and other metal smelting alloy material ratio, by crushing, pressing, sintering and aging after a magnetic material made of a high magnetic properties (high energy product, high coercivity, high remanence); a very low temperature coefficient (-0.030% / ℃), high temperature (maximum temperature of 350 ℃), negative temperature is not limited to, work temperature is above 180 ℃, the maximum energy product, temperature and chemical stability are more than NdFeB material; highly resistant to corrosion and oxidation resistance. So SmCo magnet is widely used in aerospace, defense industry, microwave devices, telecommunications, medical equipment, instrumentation, wind power, all kinds of magnetic drives, sensors, magnetic processor, high-end rare earth magnetic motors, etc. " also refers to the strong NdFeB magnets NdFeB with small size, light weight and strong magnetic features, is by far the best price-performance magnets are expected over the next 20 - 30 years, there can be no alternative to neodymium iron boron magnetic material appears. The main raw material production of NdFeB rare earth metal neodymium, praseodymium metal, iron, aluminum, boron and other rare earth material NdFeB alloy industry's core technology is mainly reflected in the manufacturing process, the specific reflected in the uniformity, consistency, processing quality, coating quality of their products and so on. As a third-generation NdFeB rare earth permanent magnet material with high performance and low cost, which are widely used in energy, transportation, machinery, medical , IT, home appliances and other industries, especially with information technology as the representative of the development of knowledge economy, to rare earth permanent magnet NdFeB industry and other functional materials continue to bring new applications, which is a broader NdFeB industry market prospects in the field of electro-acoustic industry applications Editing strong magnets: speakers, receivers, microphones, alarm, stage acoustics, car stereos and other electronic appliances: permanent magnetic actuator vacuum circuit breakers, magnetic relays, meter, water meter, sound meter, a reed switch, sensors and other electrical fields:. VCM, CDDVD-ROM, generators, motors, servo motors, micro-motors, motors, vibration motors and other mechanical equipment: magnetic separation, magnetic separation, magnetic hanging , magnetic machinery and other medical care: NMR, medical equipment, magnetic health products, magnetic fuel economy and other industries: magnetized wax, pipe descaling, magnetic fixture, automatic mahjong machine, magnetic locks, doors and windows magnetic, magnetic bags, leather magnetic toys, tools magnetic, craft gift packaging. 2 NdFeB strong magnet grades editor mainly residual magnetism, different coercivity and maximum energy product below for reference neodymium iron magnetic material, As a result of the latest development of rare earth permanent magnet material, because of its excellent magnetic properties and are called "Magneto." neodymium magnetic material is an alloy of neodymium, iron and the like. Also known as magnets. NdFeB grades are :. N30 ~ N52; 30H ~ 50H; 30SH ~ 50SH; 28UH ~ 40UH; 30EH ~ 35EH etc. is commonly used in high-magnetic magnet decided by the crystal structure of presentation: The third-generation rare earth permanent magnet NdFeB is contemporary. The strongest performance of the permanent magnet which is 5-12 times the value of BHmax ferrite magnets, is 3-10 times alnico magnet; it is equivalent to the coercive force of the ferrite magnet 5-10 times 5-15 times alnico magnets, magnetic potential is extremely high, it can pick up the equivalent of 640 times the weight of its own weight. As the main raw material of iron NdFeB magnets are very cheap, compared with reserves of rare earth neodymium samarium 10-16 times more, so the price is much lower than the samarium cobalt magnets Mechanical properties of NdFeB magnets are better than samarium cobalt magnets and alnico magnets, easier cutting and drilling and machining complex shapes. Inadequate NdFeB magnets is its poor temperature performance, high temperature magnetic loss is large, the maximum operating temperature is lower. Generally around 80 degrees Celsius, after special treatment magnet, its maximum operating temperature up to 200 degrees Celsius. Because the material contains large amounts of neodymium and iron, it is easy to corrosion is one of its major weaknesses. So NdFeB magnets have the surface coating. Nickel can be electroplated (Ni), zinc (Zn), gold (Au), chromium (Cr), epoxy resin (Epoxy) and the like. [1]
