Ι What Are AlNiCo Block Magnets?
AlNiCo, short for Aluminum-Nickel-Cobalt, is a non–rare earth metallic permanent magnet material mainly composed of Aluminum (Al), Nickel (Ni), Cobalt (Co), and Iron (Fe), with small additions of elements such as Titanium (Ti), Niobium (Nb), and Copper (Cu) to adjust coercivity. Before the rise of rare earth magnets, AlNiCo magnets dominated the permanent magnet market and are still well-known for their excellent high-temperature stability and good resistance to corrosion.
AlNiCo block magnets are one of the most straightforward AlNiCo shapes, featuring a rectangular or cuboid form. They are typically defined by length, width, and height, with the three dimensions being closer in proportion than those of AlNiCo bar magnets. AlNiCo block magnets are widely used in applications such as magnetic chucks, clamping systems, and other setups that require stable magnetic performance over a wide temperature range.
