Large 25mm x 5mm neodymium disc magnets N52 (1 25pcs)

  
Craft / Ferrite -make your own. Flexible - strip, paper, signs. Neodymium N52 - High Grade. Large 25mm x 5mm neodymium disc magnets N52 (1 - 25pcs). N52 is the highest grade which is widely available and is approximately 25% stronger than an N35 grade magnet the same size. Diameter: 25 mm (0.98). Thickness: 5 mm (0.19). Axially Magnetised through the thickness so that one flat face is north, the other is south. Maximum Temp: 80°C / 176°F. Theoretical Maximum Pull: 20.6lb / 330 oz / 9365g. Calculated Max Vertical Hold-guidance only: 4.13lb / 66.1oz / 1873g. All neodymium magnets are unsuitable for children; do not ingest. All neodymium magnets are brittle; do not allow these magnets to jump together or to an iron/steel surface - they will break, crack, chip or shatter. Serious risk of soft tissue injury if skin is trapped between magnet and steel or two magnets. They are also great for a range of crafting and DIY uses. If you need to use an adhesive, we recommend using something that will bind to metal and whatever surface you want to glue the magnet to. 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: Neodymium magnets are unsuitable for children under 8. All neodymium magnets are brittle. Do not allow these magnets to jump together or to an iron/steel surface - they will break, crack, chip or shatter. Serious risk of soft tissue injury if skin is trapped between magnets or magnet and steel. Thin neodymium magnets DO NOT FLEX, if you attempt to flex them they will snap in half.

THIS IS NOT A TOY.
