Neodymium magnets: features and purchasing options

Magnets for packaging, paper converting and professional applications.

Thanks to their high pull force, neodymium magnets are among the most powerful permanent magnets and are used in a wide range of sectors. In this article we take a closer look at the features of the N45 and N35 neodymium magnets in our catalogue and at the aspects to consider when identifying the most suitable solution for different applications. In addition to the products available in our catalogue and on our website, we also supply custom magnets in other grades and sizes.

What are neodymium magnets?

Neodymium magnets are a type of permanent magnet made mainly from an alloy of neodymium, iron and boron (NdFeB). One of their key features is their ability to generate a strong pull force even at relatively small sizes.

How to choose neodymium magnets?

When choosing and purchasing a neodymium magnet, it is important to consider a few factors:

  • Size and shape: choose the dimensions according to the intended application and the space available.
  • Magnet strength: assess the magnetic properties in relation to the required performance.
  • Coating: consider protecting the magnet from corrosion and external agents. Our neodymium magnets have a nickel or zinc coating.
  • Magnetic grade: assess the most suitable grade for the end use.
N45 and N35 neodymium magnets: features and differences

The designation N35 or N45 identifies the magnetic grade and gives an indication of the material’s performance. N35 is the most common standard grade and is a suitable solution for many applications, while higher grades, such as N45, offer greater magnetic performance. The scale also includes higher grades, up to N52. For the same shape and size, an N45 neodymium magnet can therefore offer greater magnetic force than an N35. The high magnetic force of neodymium magnets delivers good performance even at small sizes, making them easy to integrate into packaging, gift boxes, closure systems and many other professional and industrial applications.

Applications of neodymium magnets

The combination of high magnetic force and compact size makes neodymium magnets a versatile solution for many applications, from packaging and paper converting projects to closure and fastening systems, as well as various professional and industrial uses.

In packaging, for example, magnets can be inserted into the structure and concealed beneath the covering material, creating discreet and functional magnetic closures for boxes, gift boxes and other paper converting solutions. In premium packaging, a well-integrated magnetic closure preserves the look of the finished product and helps make the opening experience smoother and more refined.

However, the possible uses are not limited to packaging: shape, size and magnetic grade can be chosen according to the characteristics and performance required by the specific application. Depending on the project, you can choose between disc magnets and rectangular magnets, available in various sizes and grades, or request custom solutions.
