SOLLAU neodymium strong magnet prism 20 × 6 × 2 mm 10 pcs

The neodymium magnet (NdFeB) is currently the strongest type of permanent magnet. Their main advantage is their strength. They are created as an alloy of the rare earth element neodymium (Nd), iron (Fe), and boron (B). Thanks to these properties, these super-strong magnets can hold up to a thousand times their own weight. It's precisely this great strength that makes them so widely used. They are manufactured in many grades according to strength and temperature resistance. They are susceptible to corrosion and are therefore usually surface-treated. The most common surface treatments are nickel, zinc, and epoxy resin.
