Sintered Samarium Cobalt magnetic materials, unlike common commercial materials that have ASTM classifications, are difficult to manufacture and fabricate and present a special set of challenges. Therefore, the design team must take special care when creating a custom solution for your application. Common design challenges with SmCo Magnetic Materials include:
Are typically environmentally unstable (highly reactive and prone to oxidation). Common coating and plating solutions usually do not translate to magnetic alloy.
Will gain or lose magnetic field relative to the operational temperature fluctuations necessitating the need to design for magnetic performance through a temperature spectrum.
Can experience irreparable harm at extreme temperature exposures. This harm is irrecoverable and represents an effective partial or total demagnetization of the magnet.
Challenging to fabricate because conventional machine tools and machining methods are not feasible.
Challenging to design because the magnetic field density and resulting force are not linear relative to distance.
Magnetic fields can create hazards for personal and some electronic equipment.
Common methods of component integration and retention such as; tapped holes, shoulders, through holes, staking, and tapers are expensive to employ. The integration of a magnet into a sub-assembly requires a functional knowledge base when designing an integration scheme.
Are MAGNETIZED. This seems obvious, but magnetized magnets and sub-assemblies present a unique set handling and integration problems. The issue can range from protecting the operators to demagnetizing of the magnet itself. This aspect must be accounted for early in the design phase.
Commonly requested specifications associated with aluminum, steel alloys, plastic, etc., are usually challenging to implement with Samarium Cobalt Magnets and Samarium Cobalt Magnetic Materials. These specifications, usually indicated on a drawing by default, may add cost and complexity when manufacturing a magnet or magnetic assembly. It is important to review the relevance of these industry standard features and specifications when designing and specifying a magnet or magnetic assembly. high resistivity arc samarium magnets
