Samarium Cobalt Magnets

Attributes of Samarium Cobalt
high Resistance to Demagnetization
high Energy (magnetic Strength is Strong for Its Size)
good Temperature Stability
expensive Material (cobalt is Market Price Sensitive)
applications of Samarium Cobalt
computer Disc Drives, Sensors, Traveling Wave Tubes, Linear Actuators,
satellite Systems, Motors Where Temporary Stability is Vital.
magnetizing and Handling
samarium Cobalt Magnets are Very Brittle and Very Strong Magnetically. Therefore,
it is Crucial to Handle These Magnets with Extreme Care to Avoid Personal
injury and Damage to the Magnets. Fingers Can Be Severely Pinched Between
attracting Magnets. Magnets Can Chip if Allowed to Jump An
attracting Object. It is Highly Recommended that When Constructing Rare
earth Magnetic Assemblies, They Be Magnetized After Assembly.
samarium Cobalt Machining
since Samarium Cobalt Magnet Material is Prone to Chipping and Cracking,
it Does Not Lend Itself to Conventional Machining Methods. It Can, However,
be Abrasively Ground, But Only with the Use of Liberal Amounts of Coolant.
the Coolant Minimizes Heat Fracturing and the Risk of Fires Caused By
oxidized Grinding Dust.
