Alnico Magnets
Attributes of Both Cast and Sintered Alnico (Large Magnets)
Very stable, great for high temperature applications
Maximum working temperature 524
0
C to 549
0
C
May be ground to size
Does not lend itself to conventional machining (hard & 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)
Most common grades of Alnico are 5 & 8
Applications of Alnico Magnets
Magnetos
Security systems
Coin acceptors
Clutches and bearings
Distributors
Microphones
DC motors
Ceramic Magnets
Attributes of Ceramic Magnets
High intrinsic coercive force
Tooling is expensive
Least expensive material, compared to Akbuci and rare-earth magnets
Limited to simple shapes, due to manufacturing process
Lower service temperature than Alnico,.greater than rare-earth magnets
Finishing requires diamond cutting or grinding wheel
Lower energy product than Alnico and rare-earth magnets
Most common grades of ceramic are 5 & 8 (1-8 possible)
Grade 8 is the strongest ceramic material available
Applications of Ceramic Magnets
Speaker magnets
DC brushless motors
Magnetic Resonance Imaging (MRI)
Magnetos used on lawnmowers and outboard motors
DC permanent-magnet motors (used in cars)
Separators (separate ferrous material from nonferrous)
Used in magnetic assemblies designed for lifting, holding, retrieving and separating
