MGT-15-09 8.85-9.1kGS Rare Earth Magnetic Powder
Introduction of rare earth permanent magnet powder
Rare earth permanent magnet cloth is an alloy composed of samarium, neodymium and rare metals and transition metals (including cobalt, iron, etc.), which is pressed and sintered by powder metallurgy method. , and magnetized with the help of a magnetic field. Rare earth permanent magnets are divided into samarium cobalt (SmCo) permanent magnets and neodymium iron boron (NdFeB) permanent magnets. The magnetic power of samarium cobalt magnets is between 15 and 30 MGOe, and the magnetic power of neodymium iron boron permanent magnets is between 27 and 50 MGOe. Known as the "permanent magnet king", it is the best magnetic permanent magnet cloth at present.

Feature
The crystal shape of uncommon earth magnetic powder has excessive magnetic anisotropy. This approach that the crystals of the fabric are preferentially magnetized alongside a few crystallographic axes, however not often in different directions. Like different magnets, uncommon-earth magnets are composed of crystallite grains which can be aligned in a sturdy magnetic area in the course of manufacture in order that their magnetic axes all factor within the identical route. The resistance of the lattice to converting the route of its magnetization makes those compounds very excessive coercive (anti-demagnetization) , so sturdy demagnetization fields within the completed magnet do now no longer lessen the magnetization of the fabric.
Common applications for rare earth magnets include
Computer hard disk drives
Wind turbines
Speakers/headphones
Bicycle generators
MRI scanners
Fishing reel brakes
Permanent magnet motors in wireless tools
High performance AC servo motors
Traction motors and integrated starter generators in hybrid and electric vehicles
Mechanically powered flashlights that use rare earth magnets to generate electricity in a cranking or rotating (hand crank driven) motion
Industrial applications, such as maintaining product purity, equipment protection and quality control
Trapping of fine metal particles in lubricating oils (crankcases of internal combustion engines, but also gearboxes and differentials) to stop the circulation of said particles so that they cannot cause wear in moving machine parts
