  • +/-0.1mm manufacturers tolerance on any dimension
  • Magnetised through the thickness so that one flat face is north and the other is south
  • Samarium cobalt magnets are suited for use in damp conditions because they do not rust.
  • WARNING: These magnets are extremely brittle and will shatter if allowed to jump to another magnet or to a steel surface it is, therefore, not uncommon to find chips to edges and swarf on the magnets.  This does not affect their strength in any way.

Their uses are very varied but care must be taken because they are EXTREMELY BRITTLE if allowed to jump together or are dropped they will shatter.

Unlike neodymium magnets, they do not rust and are usually left uncoated except when being used on circuit boards when a nickel coating is used.

The pull is calculated using a mathematical formula and is, therefore, the theoretical maximum hold between one magnet and a mild steel plate. It does not take account of manufacturing tolerances, plating, plating thickness or variances in a mild steel plate. The vertical hold is based upon the calculated pull and is, therefore, only for guidance. Factors such as paint thickness, plasticised surfaces, movement and vibration are not taken into account.

WARNING: Samarium Cobalt magnets are unsuitable for children under 8. All Samarium Cobalt magnets are extremely brittle. Do not allow these magnets to jump together or to an iron/steel surface - they will break, crack, chip or shatter.
