Arc Motor Neodymium Magnet Ring High Grade NdFeB

Arc Motor Neodymium Magnet Ring High Grade NdFeB

The main raw materials of Ndfeb permanent magnet are praseodymium neodymium, dysprosium, terbium and other rare earth metals.China is a major country in rare earth resources, with the world's largest rare earth reserves and production. According to the data of the US Geological Survey, in 2021, China had 44 million tons of rare earth mineral resources, accounting for 36.67% of the global resources, ranking first in the world.In 2021, the global total output of rare earth was 280,000 tons, and China's output was 16800 tons, accounting for 60%, ranking first.Rich rare earth resources and production provide adequate supply of raw material for China's Ndfeb permanent magnet industry.

Grades of Neodymium Magnet

Neodymium( NdFeB )magnets are the type of rare earth magnet commercially available and are manufactured in a wide range of shapes,sizes and grades. Neodymium magnets are all graded by the material they are made of. As a very general rule, the higher the grade (the number
following the 'N'), the stronger the magnet. The highest grade of neodymium magnet currently available is N52. Any letter
following the grade refers to the temperature rating of the magnet. If there are no letters following the grade, then the magnet
is standard temperature neodymium. The temperature ratings are standard (no designation) - M - H - SH - UH - EH.



Platings/Coatings
Neodymium magnets are a composition of mostly Neodymium, Iron and Boron. If left exposed to the elements, the iron in the magnet
will rust. To protect the magnet from corrosion and to strengthen the brittle magnet material, it is usually preferable for the
magnet to be coated. There are a variety of options for coatings, but nickel is the most common and usually preferred. Our nickel
plated magnets are actually triple plated with layers of nickel, copper, and nickel again. This triple coating makes our magnets
much more durable than the more common single nickel plated magnets. Some other options for coating are zinc, tin, copper, epoxy,
silver and gold. Our gold plated magnets are actually quadruple plated with nickel, copper, nickel and a top coating of gold.
