Neodymium Magnets – Everything to Know About the Strongest Magnets

Neodymium magnets have occupied the topmost position in the list, being the strongest magnets in today’s world. Also known as Neo magnets, they belong to the group of magnets that are manufactured using Rare Elements, and hence are also known as Rare Magnets.

From the time neodymium magnets were found, they have been in demand in almost all industries, be it big machinery manufacturers or small production sector. Since they are quite cheaper when compared with the other magnets that are available today, they have been employed widely in many production sectors that manufacture toys, jewelry clasps, name tags, separators and filters, and so on.

What Makes Neodymium Magnets the Strongest Ones?

There are many features that are associated with the neodymium magnets, which make them the most powerful ones. Some are listed below.

  • Characteristics

When compared with the other magnets that are manufactured using Rare Earth metals, neodymium magnets are quite cheaper. Even though they are easily affordable, they will not get crippled or start cracking after years of usage. In comparison to the other Rare Earth magnet types like Samarium Cobalt (SmCo), this magnet can guarantee wonderful service for decades to come.

Unlike other magnets, neodymium magnets do not require high temperature conditions to achieve their goal. These magnets will be packed with powerful characteristic features, and hence can get the job done, even if you use a part of the whole magnet, while manufacturing any equipment or instrument. This in-turn reduces the unnecessary spending on the manufacturing of extra fittings, as required for enhancing the overall size of that particular equipment of instrument.

  • Shapes and Grades

You will find great neodymium disc magnets in market these days. The grades of such magnets start from 30 and might elevate till 52. Even though disc magnets are in great demand, the other shapes that are preferred while molding the magnet includes rod shape, rectangle, square, etc.

If you have been doing business with manufacturing unit for sometime, then you can also communicate with them to learn more about the customization of magnet shapes, which they provide. It will be of great help to you, if it is project specific requirement.

  • Coating

The basic materials that are used while manufacturing neodymium magnets are Boron, Iron and Neodymium. Additional elements such as nickel, cobalt, gold, silver, etc, will be employed during the manufacturing process. These additional elements will serve as the layer of coating, since neodymium magnets are more prone to rusting or corroding.

The basic elements such as Iron and Boron that are employed while manufacturing neodymium magnets are comparatively sensitive for humid conditions and hence, might end up damaging the chemical bonding of the magnets. The elements that are used for coating will reduce such chances of the magnets getting corroded due to humid temperatures.

  • Temperature

Neodymium magnets can stand the temperature up to 130° C, which is around 240° F. However, the capacity to withstand certain temperature of each magnet depends on the procedure that was used while manufacturing it. Hence, discussing about this with that particular producer will help you understand the temperature capacity of the magnets that you bought.
