Neodymium Magnets

Neodymium magnets, also known as super magnets, are lightweight and extremely powerful. These neodymium magnets are the strongest and most widely used among all magnetic alloys.

Neodymium (NdFeB) magnets are used in applications such as sensors, motors, wind turbines, computers, speakers, medical devices, electronics, and many industrial magnetic systems.

APPLICATIONS OF NEODYMIUM MAGNETS
Why use neodymium magnets?

The use of neodymium magnets in high-tech electronics is very common due to their high remanence and magnetic coercivity.

Neodymium magnets have the highest magnetic energy density available, with a BHmax value ranging from 30 MGOe to 52 MGOe.

They are the most powerful permanent magnets available and are made from Neodymium Iron Boron – NdFeB.

CORROSION AND DURABILITY IN NEODYMIUM MAGNETS
How can we prevent corrosion in neodymium magnets and extend their lifespan?

In addition to being the strongest, neodymium (NdFeB) magnets also possess properties that must be considered. The corrosion and mechanical fragility of neodymium magnets determine whether this type of magnet is suitable for your application.

Options to optimize the lifespan of Neodymium (NdFeB) magnets:

– A nickel-copper-nickel (NiCuNi) coating, NiCuNi + epoxy, overmolding of magnets, among other solutions, prevent corrosion and prolong lifespan. Coated neodymium magnets are also suitable for extreme conditions.
– Through magnetic alloy adjustments, certain neodymium magnets can be used at high temperatures of up to 200°C.
– A magnetic assembly or set prevents breakage or fragmentation. Read more on the magnetic bases page.
– Bonded neodymium magnets or those bonded to plastic have high resistance to corrosion. The advantage of this magnetic product is its manufacturing process, allowing for tighter geometric tolerances and flexibility in the geometric shapes of the magnets.
