N52 20mm x 4mm x 2mm Neodymium block magnets - slot car DIY MRO - PACK OF 10
- £8.430
Technical Specifications
- N52 is the highest grade which is currently widely and reliably avaialbe. In a size for size comparison an N52 grade magnet will have approximately 35% more pull than the same sized N35 grade magnet.
- Length: 20 mm (0.78")
- Width: 4 mm (0.3159")
- Thickness: 2 mm (0.07")
- Axially Magnetised through the thickness so that one 20x4mm face is north, the other is south
- Weight: 1.18g
- Grade: N52
- Coating: Ni-Cu-Ni (Nickel-Copper-Nickel)
- Maximum Temp: 80°C / 176°F
- Theoretical Maximum Pull: 7.56lb / 121oz / 3429g
- Calculated Max Vertical Hold-guidance only: 1.51lb / 24.2oz / 685g
- 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.
- Health and safety leaflet included with every purchase
These magnets are ideal for some Scalextric and some slot cars. Please note that several different sizes of magnets are used in these cars and you need to ensure have the correct one.
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.
