WARNINGS:
All samarium cobalt magnets are unsuitable for children
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.
Do not ingest
SmCo, as the second generation of rare earth permanent magnets, not only has a high magnetic energy product (14-32mgoe), but also has a reliable force, and has a good temperature characteristic in rare earth permanent magnet series.Samarium cobalt is more suitable for working in a high temperature environment than Ndfeb Magnets.
The length of the magnet means that it very easy to TIP it to it’s edge to remove it and, therefore, the pull and hold will feel significantly less than the calculation figures shown. Samarium Cobalt Cylindrical Magnets
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. Rectangle SmCo Magnet
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 magnets are unsuitable for children under 8. All 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.
