Alnico Magnets Alnico magnets are made primarily from aluminum, nickel, cobalt, copper, iron and sometimes titanium. There are cast or sintered Alnico magnet due to different process craft . Applications of Alnico Magnets • Water meter • Sensors • Electron tubes • Traveling wave tubes • Radar • Holding magnets • Clutches and bearings • Motors • Relays • Controls • Generators • Receivers • Telephones • Microphones • Bell ringers • Loudspeakers • Cow magnets • Educational products Attributes of Alnico • Very temperature stable, great for high heat applications • Working temperature can reach 550-600 °C • Does not lend itself to conventional machining (hard and brittle) • High residual induction and energy product compared to ceramic material • Low coercive force compared to ceramic and rare earth materials (more subject to demagnetization)
