In fact, yes.
CCmagnetics magnetic rings are quite simple and safe in their construction, consisting of three primary components: magnets, a metal bracket, and adhesive.
Adhesive: Typically, 3M adhesives are used, and these are all tested and certified.
Magnets: Common magnet materials include:
- Injection molded ferrite magnets
- Bonded neodymium magnets
- Injection molded neodymium magnets
- Ferrite magnets
- Neodymium magnets
- Copper metal ring/ injection molded neodymium magnets
- Copper metal ring/ injection molded ferrite magnets
- Sintered NdFeB Magnets
- Vulcanized rubber magnet material
- NdFeB plastic coating
- Sintered neodymium magnets
- Rubber magnets
These magnets have been shown to function reliably in vacuum environments.
Metal Bracket: The metal bracket is generally made from al6061, SUS304, or SUS430.
All three of these material types are considered very safe.
