Permanent Magnets
Permanent magnets retain constant magnetism after being magnetized. NdFeB magnets, a type of artificial permanent magnet, exhibit the strongest magnetic force at room temperature and are widely used across various industries, particularly in technology and energy sectors. Ferrite, a non-metallic magnetic material made from sintered Fe₂O₃ and other metal oxides, is suitable for high-frequency electromagnetic devices due to its high permeability and low eddy current loss. AlNiCo magnets, the first developed permanent magnets, are alloys of aluminum, nickel, cobalt, and iron, commonly used in instruments, electric motors, and pickups. SmCo magnets, made from samarium and cobalt, have a high magnetic energy product and can operate at temperatures up to 350°C, making them ideal for aerospace, military, and medical applications. Each of these four permanent magnet products types has unique material compositions, performance characteristics, and applications. As a professional permanent magnets manufacturer, Senz Magnet provides various types of magnet products and custom permanent magnets. Welcome to contact us!
