Can neodymium magnets be engraved with a laser?

Yes, magnets can be engraved with a laser. Laser engraving is a process in which a laser beam is used to etch a design, such as a logo, onto the surface of a magnet. The laser beam is directed onto the surface of the magnet, and the heat from the laser causes the top layer of coating to vaporize, creating a precise and detailed design.

Magnets can be made from a wide range of materials, including metals, ceramics, and composite materials. Some types of magnets, such as those made from ferrite or alnico, are more suitable for laser engraving than others due to their hardness and melting points. In general, magnets made from softer materials are more prone to being damaged by the heat of the laser, so it is important to select the appropriate type of magnet for a given application.

Laser engraving is a precise and accurate method of marking magnets, and it is often used in applications where the magnet needs to have detailed or complex markings/designs. It is also a good choice for applications where the markings need to be permanent and resistant to wear and tear.
