Permanent-magnetic, High Power Scrap Lifting Magnet (high power magnets)
Basic Info
Model No.: N35-N52, N35-N52
Product Description
Product Description What is Ndfeb? Neodymium is a metal which is ferromagnetic (more specifically it shows antiferromagnetic properties), meaning that like iron it can be magnetized to become a magnet, but its Curie temperature (the temperature above which its ferromagnetism disappears) is 19 K (−254 °C), so in pure form its magnetism only appears at extremely low temperatures. However, compounds of neodymium with transition metals such as iron can have Curie temperatures well above room temperature, and these are used to make neodymium magnets.
The strength of neodymium magnets is due to several factors. The most important is that the tetragonal Nd2Fe14B crystal structure has exceptionally high uniaxial magnetocrystalline anisotropy (HA ~7 T – magnetic field strength H in units of A/m versus magnetic moment in A·m2).This means a crystal of the material preferentially magnetizes along a specific crystal axis, but is very difficult to magnetize in other directions. Like other magnets, the neodymium magnet alloy is composed of microcrystalline grains which are aligned in a powerful magnetic field during manufacture so their magnetic axes all point in the same direction. The resistance of the crystal lattice to turning its direction of magnetization gives the compound a very high coercivity, or resistance to being demagnetized.

Producing Process 
Factory Our factory are located in Ma' anshan city,where is only 40 minutes' drive away from Nanjing.The flexibility of our organization and magnagement,high efficiency of cost control and advanced standard of quality assurance, have earned us strong partnership with several high-tech enterprises,with whom we work together in magnets reserarch and application.
High performance ferrite powder segment magnet in the fied of the auto cars and inverter appliances series ,motor startors,have reached the performance of FB6, FB9 series of TDK in Japan.
There are two principal neodymium magnet manufacturing methods:
Classical powder metallurgy or sintered magnet process[11]
Rapid solidification or bonded magnet process
Sintered Nd-magnets are prepared by the raw materials being melted in a furnace, cast into a mold and cooled to form ingots. The ingots are pulverized and milled; the powder is then sintered into dense blocks. The blocks are then heat-treated, cut to shape, surface treated and magnetized.
In 2015, Nitto Denko Corporation of Japan announced their development of a new method of sintering neodymium magnet material. The method exploits an "organic/inorganic hybrid technology" to form a clay-like mixture that can be fashioned into various shapes for sintering. Most importantly, it is said to be possible to control a non-uniform orientation of the magnetic field in the sintered material to locally concentrate the field to, e.g., improve the performance of electric motors. Mass production is planned for 2017.
As of 2012, 50,000 tons of neodymium magnets are produced officially each year in China, and 80,000 tons in a "company-by-company" build-up done in 2013.China produces more than 95% of rare earth elements, and produces about 76% of the world's total rare-earth magnets.
Bonded Nd-magnets are prepared by melt spinning a thin ribbon of the NdFeB alloy. The ribbon contains randomly oriented Nd2Fe14B nano-scale grains. This ribbon is then pulverized into particles, mixed with a polymer, and either compression- or injection-molded into bonded magnets. Bonded magnets offer less flux intensity than sintered magnets, but can be net-shape formed into intricately shaped parts, as is typical with Halbach arrays or arcs, trapezoids and other shapes and assemblies (e.g. Pot Magnets, Separator Grids, etc.)[not in citation given] There are approximately 5,500 tons of Neo bonded magnets produced each year.[when?][citation needed] In addition, it is possible to hot-press the melt spun nanocrystalline particles into fully dense isotropic magnets, and then upset-forge or back-extrude these into high-energy anisotropic magnets.
Related Products Application: Neodymium magnets have replaced alnico and ferrite magnets in many of the myriad applications in modern technology where strong permanent magnets are required, because their greater strength allows the use of smaller, lighter magnets for a given application. Some examples are:
Head actuators for computer hard disks
Erase heads for cheap cassette recorders
Magnetic resonance imaging (MRI)
Mechanical e-cigarette firing switches
Locks for doors
Loudspeakers and headphones
magnetic bearings and couplings
Benchtop NMR spectrometers
Electric motors:
Cordless tools
Servomotors
Lifting and compressor motors
Synchronous motors
Spindle and stepper motors
Electrical power steering
Drive motors for hybrid and electric vehicles. The electric motors of each Toyota Prius require 1 kilogram (2.2 pounds) of neodymium.[18]
Actuators
Electric generators for wind turbines (only those with Permanent Magnet excitation)
direct-drive wind turbines require c. 600 kg of PM material per megawatt[citation needed]
turbines using gears require less PM material per megawatt[citation needed]
Toys
Neodymium content is estimated to be 31% of magnet weight
