Preparation process of sintered NdFeB magnets (3) - orientation forming Magnetic field orientation forming is to use the interaction between magnetic powder and external magnetic field to arrange the easy magnetization direction of powder particles so that it is consistent with the final magnetization direction of the magnet. This is the most commonly used method [...]
Preparation process of sintered NdFeB magnets (4) - Sintering, heat treatment and machining Sintering and heat treatment The blanks pressed by magnetic field orientation are sintered in a high vacuum or pure inert atmosphere to reach a high density close to 95% of the theoretical density. The magnet holes are in a closed structure, which [...]
NdFeB chemical composition analysis (ICP analysis) The chemical composition analysis of NdFeB materials generally includes: 1-Chemical composition analysis of raw materials, including the chemical composition of rare earth metal raw materials, as well as industrial pure Fe, B-Fe alloys and other metals, such as Ga, Al, Nb, Zr, etc.; 2- The chemical composition of the [...]
Application of High Performance Sintered NdFeB Magnets in Wind Power Generators Abstract: The permanent magnet wind turbine adopts high-performance sintered NdFeB permanent magnets, and the high enough coercive force can prevent the magnets from demagnetization at high temperature. The life of the magnet depends on the substrate material and surface anti-corrosion treatment. The anti-corrosion of [...]
Does magnet have radiation? Can it be placed at home? The magnetic force of magnets on the market is relatively small and will not generate a large magnetic field, so the magnetic radiation it produces is mostly less powerful, and this radiation is mainly aimed at metallic substances, which is why magnets can firmly attract [...]
