Product Description
This product measures 101.6mm (4") in diameter and 12.7mm (1/2") in thickness and features a 50.8mm(2") hole through the thickness of the magnet. It is made of a grade N45 neodymium, iron, and boron magnetic alloy blend. This magnetic blend is patent licensed and made under the ISO 9001 quality control systems. They are plated in a nickel-copper-nickel coating for a shiny corrosion resistant finish. Neodymium ring magnets are perfect for use as magnetic fasteners around the home or for use in commercial applications.
Please note that all neodymium rare earth magnets are fragile and require caution when installing to prevent shattering the magnet due to their brittle nature, and to avoid injury due to pinching.
- Material: Sintered NdFeB. Grade N45 (The product is also available in grade N35/N38/N42/N45/N50/N52, please contact us for special order)
- Gauss Rating: 13,500 Gauss
- Pulling Force: 73kg
- Pole Orientation: Axially magnetized, the poles are on the two flat surfaces.
- Coating: Ni+Cu+Ni 3 layer coating, the best available.
- Tolerance: The tolerances of all the dimensions are +/-0.05mm with coating.
This is the largest ring magnet in stock but we can make 203.2mm (8") rings for speakers. Should you need a quotation for the larger magnets, please contact us.
PLEASE NOTE:
- All magnets may chip and shatter, but if used correctly, can last a lifetime.
- Keep away from pacemakers.
- Not for children, parental supervision required.
- COMMERCIAL USE ONLY.
- If damaged please dispose of completely. Shards are still magnetized and if swallowed can inflict serious damage if magnets join inside the digestive tract.
