NdFeb Magnets Not degaussing

NdFeB magnets and ferrite magnets are two kinds of magnets commonly used in industrial production. With a large magnetic, easy demagnetization and other aspects of a little bit. So who is more of a little bit of magnetic it, on this issue with you to discuss.

   Strong magnets are generally neodymium iron boron structure, the normal suction stone should be ordinary ferrite material.

   Rare earth NdFeB magnets (commonly known as: powerful magnets, electroplated magnets, magnets):

   Is the most unique magnetic force, high performance, can be electroplated, (the most commonly used only galvanized ZN, nickel-plated, nickel-plated, nickel-plated, nickel-plated, nickel-plated, nickel-plated NI; also some special requirements, such as gold-plated, silver, plated, etc., according to the demand we can electroplating) fast delivery, easy transportation, widely used in the market is now the most common kind of magnet; mainly used for printing and packaging , Electronics, electrical appliances, mining equipment, electrical and other fields;

   Ferrite magnets:

   Its main raw material is ferric oxide. Made by molding, the texture is relatively hard, is a brittle material, because the ferrite magnet has a good temperature resistance, low price, moderate performance, is currently widely used in the market permanent magnet. Features: homogeneous Y10 Y20 Y25 heterosexual Y30; heterosexual than the same magnetic force is better, the hardness should be strong; the opposite sex can also be used to strengthen the type of Y30BH; the same time, the price is too high, easy to oxidize, poor magnetic, transport trouble, product shipments slow;

   So because of the different material and structure, which led to the role between the two is not the same. NdFeB single magnetic field of suction than ferrite about 30 to 50 times the same size (under the premise of the same specifications), combined magnetic system inside the NdFeB magnetic field strength higher.

Please note: the ferrite magnet installation is very convenient, but the installation of NdFeB combined magnetic system, the professional installation personnel to install, or may lead to personal injury.

   Rare earth elements in the application of magnetic materials increased, cerium, praseodymium, neodymium, samarium and dysprosium and other elements for permanent magnet materials, and varieties and performance are constantly developing and improving. With the development of modern industry and technology, rare earth permanent magnet material requirements are also growing.

   Commonly used metals are the following: metal neodymium, praseodymium neodymium, boron, boron, copper, aluminum, gallium, terbium, cobalt, iron, dysprosium, ferroniobium.

   High-performance NdFeB permanent magnet magnetic level is largely determined by the production process, Japan is the leading technology in this area. High-performance NdFeB permanent magnet material is the main raw material for rare earth, rare earth is divided into light rare earth and heavy rare earth. At present, China's high-performance NdFeB permanent magnet materials are mainly used for wind power and energy-saving elevators. In the next few years, wind power and energy-saving elevators can be developed rapidly, so that it can greatly save resources, but also contribute to environmental protection, or a lot of benefits. Of course, NdFeB permanent magnet is also used in all walks of life, such as the automotive industry, machinery industry, etc., are more or less designed to permanent magnet materials, which can be said to be essential.
