Characteristics of NdFeB magnets: NdFeB is found in the commercialization of the highest performance magnets, known as Magneto, with a high maximum magnetic energy product (BHmax) higher than the ferrite (Ferrite) 10 times the above. It is also known as: magnetic, magnet and so on. Machining performance itself is also quite good. Operating temperature up to 200 degrees Celsius. And its hard, stable performance, there is a very good price, so its application is extremely broad. But because of its chemical activity is very strong, it must deal with its surface. NdFeB permanent magnet materials are intermetallic compounds based Nd2Fe14B permanent magnetic materials. With respect to the casting Al-Ni-Co permanent magnetic materials and ferrite permanent magnet materials, NdFeB has high energy product and coercive force, can pick up the equivalent of 640 times its own weight of heavy loads. The advantages of high energy density make NdFeB been widely used in modern industrial and electronic technology, so that the instrumentation, electro-acoustic motors, magnetic separation equipment such as magnetic small, lightweight, thin as possible. Advantages NdFeB material characteristics are high cost performance, with good mechanical properties, ease of cutting; downside is that the low point of the Curie temperature, the temperature characteristics are poor, and easy chalking corrosion, must adjust their chemical composition and taken to a surface treatment method is improved so as to meet the requirement of practical application. Manufacturing process NdFeB powder metallurgy manufacturing process, will contain a certain proportion of raw materials such as: neodymium, dysprosium, iron, cobalt, niobium, praseodymium, aluminum, copper, boron and iron smelting by medium frequency induction melting furnace into the alloy ingot, 3 ~ 5μm then crushed into powder, and pressing in a magnetic field, forming a green compact after sintering and tempering aging in a vacuum sintering furnace, so you get a permanent magnet has a magnetic properties blank. After rough grinding, drilling, slicing and other machining processes, and then the surface treatment is required by the user NdFeB products.

Be sure to check before ordering temperature and good grades for their own use. 2, the magnet device environment if used in a sealed condition, you can consider choosing the surface is not plated or white zinc plated magnet, so you can save the cost, if the magnet is exposed to moist air, especially under the fog, it is recommended to consider plated magnet nickel processing. Magnets should be stored in dry, heated environment, use plastic, wood, cardboard, foam and wrapped separated. Easily magnetized iron and should stay away from items such as monitors, bank cards, computers, televisions, mobile phones and so on. 3, handling and stacking NdFeB magnetic materials hard, brittle, magnetic field strength, to handle it gently (especially large size and thin), when strong magnet attraction in itself or in combination with other iron or separation, be careful operation not impact . Otherwise easily lead to damage due to collision magnet or pinch your fingers. Because NdFeB is a multi-metal alloys, density of between 7.45 and has heavy and brittle characteristics. So be especially careful when handling to take action to avoid magnetic pieces. When the warehouse should also keep the environment dry, do not directly stacked on the ground, the best cardboard mat or placed on shelves. 4, access to notes from the time when the magnets attract each other inseparable recommend flat push stagger, must not hard pull to pry. With his left hand the whole fixed magnet, with the right hand with the index finger and thumb, horizontal magnet aside, do not immediately put aside after aside magnet magnet back into the pile, immediately isolate the magnet. Gently away from things with magnetic iron or further afield (16 centimeters) or put the paper wrapped thick wrap removed, so that it is safer. If you need to replace the entire magnet magnet inside, please take back, close to the edge of the start moved inside. Be sure to grasp the hand magnet until the magnet has been moved inside.
