Strong 12mm x 4mm neodymium disc magnets N52 5 - 250 pcs DIY craft
Technical Specifications
- N52 is the highest grade which is currently widely and reliably available. In a size for size comparison an N52 grade magnet will have approximately 35% more pull than the same sized N35 grade magnet.
- Diameter: 12 mm (0.47")
- Thickness: 4 mm (0.15")
- Axially Magnetised through the thickness so that one flat face is north, the other is south
- Weight: 3.45g
- Grade: N52
- Coating: Ni-Cu-Ni (Nickel-Copper-Nickel)
- Maximum Temp: 80°C / 176°F
- Theoretical Maximum Pull: 8.04lb / 129oz / 3646g
- Calculated Max Vertical Hold-guidance only: 1.6lb / 25.8oz / 729g
- WARNINGS:
- 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.
- Thin neodymium magnets DO NOT FLEX, if you attempt to flex them they will snap in half.
These are for a range of hobby crafting uses model making and homemade fridge magnets. They are also good for DIY and MRO 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.
