Super Strong Rare Earth Sintered NdFeB Magnets for Machinery

Rare Earth

Neodymium magnets are a member of the Rare Earth magnet family and are the most powerful permanent magnets in the world. They are also referred to as NdFeB magnets, or NIB, because they are composed mainly of Neodymium (Nd), Iron (Fe) and Boron (B). They are a relatively new invention and have only recently become affordable for everyday use.

They are widely used in industries of electronics, machinery, communication equipment, chemistry, biology, medicine and high-tech fields such as aerospace, aviation, military etc. Moreover they are used in emerging industries as well like new energy industry of wind power and new energy vehicles.

Grades of Neodymium

N35, N38, N42, N38SH...what does it all mean? 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.  You find the temperature rating of each grade on our Specifications of Neodymium Magnets Form.

Specifications of Neodymium Magnets

If you need detailed information about the physical and thermal properties of neodymium magnetic materials, you can find it on our Specifications of Neodymium Magnets Form. MagTrust can produce according to customer\'s design professional magnets of various shapes and sizes. Magtrust is willing to know more about your special demands and will provide a full magnetic solution to you.
Also we can do minimal size Diameter 1*0.5mm ~D1.9*0.5mm of sintering NdFeB that is a few manufacturers can do in magnetic field.

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.
