In our daily life and work, we often use magnets (permanent magnets) to attach iron products, so can it attach aluminum? Is there any way to make the magnet attach to aluminum?
Magnets cannot stick directly to aluminum because aluminum is a non-ferromagnetic metal and will not be attracted to ordinary magnets. Although aluminum can be affected by strong magnetic fields (e.g. eddy current effect), it does not possess magnetic properties by itself like materials such as iron, nickel and cobalt. Therefore, if you want a magnet to attach to an aluminum product, you need to use some special methods.

Possible ways to get magnets to attach to aluminum
1. Use strong glue
If you need to fix the magnet to an aluminum surface, you can use a strong adhesive such as epoxy glue, 502 glue or 3M double-sided tape. This method is suitable for long-term fixing and is not suitable for situations where the magnet needs to be moved or replaced frequently.
2. Installation of a layer of ferromagnetic material on the aluminum surface
First install a layer of ferromagnetic material (such as iron or steel sheet) on the aluminum surface, and then let the magnet adsorb on this layer. This method is suitable for aluminum doors and windows, aluminum shell equipment and other scenarios, and can achieve the effect of magnetic suction.
3. Punching holes in aluminum
Fixing the magnet with holes with screws or rivets, suitable for load-bearing needs.
4. Self-adhesive backing on magnet surface
Depending on the need for magnetism, you can choose neodymium material, flexible rubber magnet. Ferrite is not effective due to its non-smooth surface.

The final conclusion is that magnets cannot directly adhere (adsorb) to aluminum, but can be attached through methods such as glue, adding iron sheets, punching holes, and applying double-sided tape.
