4.2  Grades of Neodymium Magnet

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.

4.3  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.

How are Neodymium Magnets made?

The main ingredients are Neodymium, Iron and Boron. The exact ingredients depend on the grade being produced. We also add a key ingredient called dysprosium to raise the coercivity of the material and increase the resistance to demagnetisation and corrosion. You can read more about the manufacturing process in our company website u-polemag.com

How long for neodymium magnets?

The production of neodymium magnets is a complicated process, it will take about 15-30days in generally
