NdFeB Magnet Characterized By Small Volume, Light Weight And Magnetic Strength

NdFeB magnets are characterized by small size, light weight and strong magnetic properties, which are the best magnets to date. It is expected that in the next 20-30 years there will be no substitute for NdFeB magnets. The main raw materials for the production of NdFeB magnets are metal neodymium, pure iron, boron alloy and other additives.

The core technology of NdFeB magnet industry is mainly embodied in the manufacturing process, which is embodied in its product uniformity, consistency, processing quality, coating quality and so on.

ND-FE-B magnets as the third generation of rare earth permanent magnets, with high performance and price ratio, it is widely used in energy, transportation, machinery, medical, IT, home appliances and other industries, especially with the information technology as the representative of the development of knowledge economy, the rare earth Permanent magnet NdFeB industry and other functional materials continue to bring new uses, This brings a broader market prospect for the NdFeB industry.

ND-FE-B Permanent magnet is a national 863 Project program Project High-tech materials. What he can produce is a biological magnetic field that simulates the characteristics of the human body's magnetic field, stable performance! The human body can be used to rectify the magnetic field of the human body, by enhancing the bio-electromagnetic energy of the meridian, promoting the operation of the meridians, so as to reach the meridian, increase the blood supply of the brain and decrease the excitability of the cerebral cortex peripheral, the effect of promoting the metabolism, hypnosis, analgesia, sedation, activating blood circulation and eliminating anxiety of the bone joint tissue was produced. Currently commonly used to treat insomnia, neurasthenia, cervical spondylosis, scapulohumeral periarthritis, such as chronic bone and joint diseases, as well as these diseases caused by pain, numbness and other symptoms.

The advantages of NdFeB magnets are high cost-performance, good mechanical properties, low Ugury temperature points, poor temperature characteristics, and easy to powder corrosion, it is necessary to adjust its chemical composition and adopt surface treatment methods to make it improved, in order to meet the requirements of practical application. NdFeB belongs to the third generation of rare earth permanent magnetic materials, with small size, light weight and strong magnetic characteristics, is the current performance price than the best magnet, in the magnetic field is known as Magneto. The advantages of high energy density make NdFeB permanent magnet materials widely used in modern industry and electronic technology. In the naked magnetic State, the magnetic force can reach about 3500 gauss.

ND-FE-B magnets are the quartet crystals formed by neodymium, Iron and Boron (nd2fe14b). The magnetic energy product of this magnet (Bhmax) is larger than samarium cobalt magnets, which is the most energy-accumulating substance in the world at that time. Later, Sumitomo Special metal developed successfully in Powder Metallurgy (Svec metallurgy process), and General Motors developed a successful spin-spraying smelting process (melt-spinning) to produce NdFeB magnets. This magnet is now the most magnetic permanent magnet, is also the most commonly used rare earth magnet (rare ground magnet), is widely used in electronic products, such as hard disk, mobile phones, headphones and battery-powered tools and so on.

In order to avoid corrosion damage, the use of the permanent magnet material surface to do the protection, such as gold, nickel, zinc, tin plating, and surface spraying epoxy resin.
