Sintered neodymium iron boron permanent magnetic material products should provide the technical magnetic parameters of the product, including remanence Br, magnetic induction coercive force Hcb, intrinsic coercive force Hcj, magne…
The corrosion resistance of sintered neodymium iron boron permanent magnets is not only related to the corrosion resistance of the substrate, but also related to the type of coating on the magnet surface, the thickness of the coat…
What are the mechanical properties of materials? The mechanical properties of materials generally include strength, hardness, plasticity and toughness, which have different physical meanings. Strength refers to the maximum ability…
The demagnetization of the magnet caused by heating is certain, and the experiment is very simple! Then the earth's internal temperature is even as high as 6000 degrees, and even high-temperature magnets have been demagnetized. Wh…
Nd-Fe-B magnet is mainly used in permanent magnet DC motor. Different from electromagnetic motor which generates magnetic field through excitation coil, permanent magnet motor generates constant magnetic field source with permanen…
Daido Steel Co., Ltd. and Honda Motor Co., Ltd. have developed a practical hot deformed neodymium magnet containing no heavy rare earth elements (REE) that still delivers the high heat resistance properties and high magnetic perfo…
