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)
