Working with Neodymium Magnets

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...

What is the best way to work with self-adhesive magnets?

Self-adhesive magnets enable you to attach the magnet to a non-magnetic surface, such as aluminum, wood, plastic, ceramic, rubber, paper, and other non-ferrous materials. We have both block and disc shaped self adhesive magnets available.Normally, these magnets come in packs with half self-adhesive on the north side, and half with the self adhesive on the south side. This enables them to attract if needed to form a closure or fastener.  Our adhesive magnets are made with a foam based acrylic adhesive, which is also available separately as double-sided self-adhesive stickers. This high-performance adhesive delivers excellent shear strength to resist slippage and edge-lifting. Simply peel the paper off...

How are steel strike plates and magnets used most effectively?

Steel discs (often called strike plates) offer added flexibility when working with magnets. They can be used in place of a magnet in some applications because they make an ideal target for other magnets to attract to and attach with. This can dramatically lower your production or project expenses as steel discs cost significantly less than magnets.Due to their ultra thin profile, these blank steel discs can be used to create a variety of magnetic catches, latches, packaging and box closure mechanisms – again, without the cost of an additional magnet. As a result, these discs are ideal for a...

What materials can I use to block/shield magnetic fields?

Magnetic fields cannot be blocked, only redirected. The materials that will redirect magnetic fields are materials that are ferromagnetic (attracted to magnets), such as iron, steel (which contains iron), cobalt, and nickel.  Iron: Iron is a ferromagnetic material, which means it is strongly attracted to magnets and can be used to block a magnetic field. Steel: Steel is also ferromagnetic and can be used to block a magnetic field. Mu-metal: Mu-metal is an alloy that is made up of several ferromagnetic materials, including nickel, iron, and cobalt. It is highly effective at shielding magnetic fields. Other Metals: Other metals, such...

Can I solder or weld to neodymium magnets?

Direct soldering or welding to neodymium magnets is generally not advised since the high temperatures involved in these techniques may harm the magnets. Neodymium magnets are prone to corrosion and degeneration when exposed to high temperatures since they are made of an alloy of neodymium, iron, and boron. It is advised to utilize a low-temperature bonding technique, like an adhesive, or a mechanical connection technique, like screws or bolts, if you need to fasten something to a neodymium magnet.
