Ring Magnets Made of Grade N42 Neodymium Rare Earth Magnetic Material
OD = 1" , ID = 1/2+0.002/-0.000", Thickness = 1/4"
This ring magnet measures 1" in diameter and 1/4" in thickness and features a 1/2" center hole through the thickness. It is made of a grade N42 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.
- Material: Sintered NdFeB. Grade N42
- Gauss Rating: 13,200 Gauss
- Pulling Force: 19 lbs.
- Pole Orientation: Axially magnetized, i.e. the N and S poles are on the flat surfaces
- Coating: Ni+Cu+Ni 3 layer coating, the best available.
- Tolerance: The tolerances of all the dimensions are +/-0.002in with coating.
- All magnets may chip and shatter, but if used correctly, can last a lifetime.
- Keep away from pacemakers.
- Not for children, parental supervision required.
- If damaged please dispose of completely. Shards are still magnetized and if swallowed can inflict serious damage if magnets join inside the digestive tract.
- Please note that all neodymium rare earth magnets are fragile and require caution when installing to prevent shattering the magnet, and when handling due to their brittle nature and to avoid injury due to pinching.
Other DetailsThis product is covered by 10 year warranty on the magnetic strength under normal usage. Used in the environment which has high temperature and virbation will void this warranty. The product should not be used in the outdoor or high humid or salty environment except extra insulation measurement is taken.
