Discover the Truth: Will neodymium magnets stick to aluminum?

Neodymium magnets are renowned for being among the most powerful permanent magnets globally. They have gained widespread use across various industries owing to their high magnetic strength and remarkable durability. Nevertheless, a joint inquiry among many people pertains to whether neodymium magnets can cling to aluminum. This piece will delve into the science of magnetism and aluminum and provide a detailed answer to this inquiry.

An alloy of neodymium, iron, and boron makes neodymium-magneter, which exhibit high magnetic strength and find widespread use in various applications such as electric motors, loudspeakers, MRI machines, and more. Meanwhile, various applications widely use aluminum because it is a lightweight, silvery-white metal with strength, durability, and low density.

Understanding Magnetism

Certain materials, known as magnetism, possess the property of attracting or repelling each other. The strength of magnetism relies on the magnetic field and orientation of the material. Neodymium magnets exhibit a high magnetic field strength because of their atomic structure alignment, enabling them to attract ferromagnetic materials such as iron, nickel, and cobalt.

Understanding Aluminum

Aluminum, a non-magnetic metal, exhibits a magnetic permeability of low order, thereby rendering it impervious to magnetization. Nevertheless, aluminum succumbs to its influence upon exposure to a potent magnetic field and acquires a degree of magnetism, albeit slightly.

Will Neodymium Magnets Stick to Aluminum?

The simple answer is no. Neodymium magnets cannot stick to aluminum because it is not a ferromagnetic material with a strong attraction to magnets. Materials with magnetic properties like iron, nickel, and cobalt are the ones that neodymium magnets will stick to. In summary, neodymium magnets do not stick to aluminum.

So while these magnets are powerful, they won’t have any attraction to aluminum. Remembering this if you plan to use neodymium magnets for a project is essential. You must choose ferromagnetic materials such as iron, nickel, and cobalt, as using them on the wrong materials could lead to disappointment and frustration.

Factors Affecting Magnetism of Aluminum

Although aluminum does not possess magnetic properties, exposure to a magnetic field can influence its magnetism. Some factors that can affect its magnetism in such circumstances include:

  • Purity of Aluminum: The purer aluminum, the lower its magnetic permeability and the less susceptible it is to magnetization.
  • The thickness of Aluminum: The magnetic permeability of aluminum decreases as its thickness increases, making it less susceptible to magnetization.
  • Temperature: At lower temperatures, aluminum exhibits an increased magnetic susceptibility, making it more prone to magnetization in cold environments.

How to get a magnet to stick to aluminum?

You can use metal adhesive or double-sided tape to attach magnets to aluminum, which possesses a solid adhesive property capable of bonding the neodymium magnets to aluminum surfaces.

Metal adhesive ensures a durable and long-lasting fix, while double-sided tape offers a quick and easy solution. Therefore, if one experiences issues with neodymium magnets not sticking to aluminum, you should consider using metal adhesive or double-sided tape to attach the magnets to the aluminum surface securely.

Do any magnets stick to aluminum?

No, aluminum and other non-ferromagnetic metals such as copper, silver, gold, brass, and lead do not stick to magnets because they are weak magnetic materials. Unlike ferromagnetic materials such as iron, nickel, and Cobalt which are firmly magnetic, these metals are only paramagnetic and exhibit a weak magnetic effect when exposed to a magnetic field. Therefore, you won’t find any magnet sticking to aluminum anytime soon as it lacks the magnetic power to attract or repel any magnetic object.


In conclusion, we can assert that aluminum is not a ferromagnetic material, and as a result, neodymium magnets will not adhere to it. Nevertheless, certain factors may influence the magnetism of aluminum when subjected to a magnetic field. One can use metal adhesive or double-sided tape to attach neodymium magnets to aluminum while ensuring proper safety precautions to avoid any potential injuries when handling these materials.
