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.
