Powerful magnets explain how powerful magnets made of NdFeB permanent magnet materials and can be called, powerful magnets can be divided into bonded NdFeB sintered NdFeB and characteristics of these two magnets are: bonded neodymium each direction has a magnetic iron boron, corrosion; NdFeB easy due to corrosion, the surface to be coated, such as: zinc, nickel, zinc and environmental protection, environmental protection, nickel, nickel-copper-nickel, nickel-copper-nickel and other environmental protection. The method of manufacturing a strong magnet powder metallurgy method, the melt-quenching method, reduction of diffusion bonded magnets and four methods, powerful magnets sintered multiphase system, in addition to Nd2Fe14B, there exist Nd-rich, so melting press Nd15Fe77B8 nominal component ingredients, the obtained alloy ingot by a powder milled to a particle size of about 3μm, and then press-molded in a magnetic field perpendicular to the outer (~ 10kOe) direction. Suppress blank at about 1380K under the protection of the sintering atmosphere, followed by rapid cooling. Then post-baked at a temperature of the melting point of the Nd-rich phase (around 880K), and then quickly cooled. Powerful magnets applied to the right path in our daily lives, the usefulness of the magnet is very broad. It gives us the general public has brought great convenience and usefulness. Especially in the electronics industry, its usefulness can be described as very broad, it can be said is indispensable, but some profiteers take advantage of it as the road to fortune. Xiao Bian recently saw a news report this magnet, which makes small series of meditation for a long time, television coverage is xxx road stalls magnet, do not send traders under Zongmu Kuikui magnet broken child, for their own self-interest, since the use of magnet sales undermine national interests steal appliances, display the picture of those vendors are very enthusiastic, where the magic show strong magnet magnet fence, whether it is stealing, stealing water, stealing gas, can be. The price is very affordable and low as long as 10 yuan, the highest as long as 40 yuan. Crowd of people very much, especially the articles that reported to be very popular. In our country a lot of things like this, this thing has a lot, I do not know how relevant departments are seeing this thing, and traders who earn that kind of money, so the people who save money.
