The importance of the work of anti-corrosion of Nd-Fe-B magnet
21/11/2016
Nd-Fe-B magnet is very easy to be corroded.Therefore, most of the finished product to plating or coating.Routine used in surface treatment including: nickel (nickel-copper-nickel, zinc, aluminum, such as electrophoresis.If the work in a confined environment, can also be used phosphate way.strong magnetic hooks
Neodymium-iron-boron magnet are used widely at present, the rapid development of magnet products.Neodymium-iron-boron from the wide application of the invention to now, only 20 years of time.Because of its high magnetic properties and ease of processing, the price is not high, so the rapid expansion of the application field.At present, neodymium-iron-boron of commercialization, magnetic energy product can reach the 50MGOe, the ferrite is 10 times.
Nd-Fe-B magnet is also a powder metallurgy products, processing methods and samarium cobalt similar.At present, neodymium-iron-boron maximum working temperature of 180 degrees Celsius.If it is the application of harsh environments, the general recommendation no more than 140 degrees Celsius.
The maximum energy product of the Nd-Fe-B magnet is 5~15 times of sintered ferrite, the intrinsic coercivity is 5~10 times that of ferrite, is 6~10 times of the Al-Ni-Co; The potential of the magnetic properties of Nd-Fe-B is very high, in theory, its magnetic energy product can reach the 527kJ/m3 (66MGOe), and even can lift objects than their own weight of 640 times.Because of easy corrosion of sintered Nd-Fe-B, its application is limited; In high humidity and high temperature, High-acidity, the application of high alkali environment, The importance of sintered Nd-Fe-B surface coating, electroplating coating methods that can be taken (Zn, Ni, NiCuNi, AU etc), electrophoresis of (epoxy resin), Parylene, and the combination of these coatings;Office Push Pin
Recently, along with the composition and process of technological innovation, the corrosion resistance and the temperature stability has made remarkable improvements.However, so far, the temperature stability of Nd-Fe-B material is bad, the loss of the magnetic flux at high temperature is still large.
specialized in manufacturing all kinds of rare-earth permanent magnets, According to the customers request, we can produce all kinds of NdFeB magnets with different complicated shapes and get them magnetized with multi-poles. The products are widely used in motor, micromotor, computer, instrument, car, motorcycle, amera, watch, HiFi, electric appliances, office automation, toy, magnetic therapy and other fields of daily life.
