Guy's Budget Range 12 mm x 5 mm N38 grade disk - PACK OF 25
Item Code (SKU): ECON-727-25Technical Specifications
- These are from our BUDGET RANGE of magnets, ideal for the budget conscious when the tolerances are less important than normal. Instead of our usual +/-0.1mm tolerances, they have +/-5% tolerances on any dimension.
- Diameter: 12 mm (0.47")
- Thickness: 5 mm (0.19")
- Axially Magnetised through the thickness so that one flat face is north, the other is south
- Weight: 4.18g
- Grade: N38
- Coating: Ni-Cu-Ni (Nickel-Copper-Nickel)
- Maximum Temp: 80°C / 176°F
- Theoretical Maximum Pull: 8.1lb / 129oz / 3665g
- Calculated Max Vertical Hold-guidance only: 1.62lb / 25.8oz / 733g
- 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 ideal for making magnetic door/drawer closures. Embed one magnet in either the door/drawer and another in the frame, taking care to make sure they attract, not repel. If space is an issue, use one magnet and a countersunk washer as a 'striker plate'. Fix in place with a 2 part epoxy resin or similar adhesive.
They are also great for a range of MRO 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 although it takes account of the centre hole, it does NOT take account of the countersink is, therefore, the only an estimate of 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. Thin neodymium magnets DO NOT FLEX, if you attempt to flex them they will snap in half. THIS IS NOT A TOY. DO NOT INGEST
