The MAGNET ALNICO 3 x 12 mm is a powerful durable permanent magnet made from alnico material. It has a diameter of 12 mm and a thickness of 3 mm. The magnet provides a very strong magnetic field with minimal space consumption and its magnetic qualities remain stable over time. The alnico material gives it great resistance to corrosion and the magnet has a high temperature tolerance, up to 260 degrees Celsius. It is a perfect choice for applications that require a reliable and powerful magnet, such as industrial sensors and motors, magnetic couplings, and sound systems.
