Product Description
This powerful neodymium block magnet measures 4" in length, 1" in width, and 1/2" thickness and 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 and are plated in a nickel-copper-nickel triple layer coating for a shiny corrosion resistant finish. This magnet is great for holding purposes such as holding objects to magnetic surfaces. Moreover, this magnet is versatile and robust; applications range from industrial use to personal projects.
Please note that all neodymium rare earth magnets are fragile and require extreme caution when handling due to their brittle nature and to avoid injury due to pinching.
- Material: Sintered NdFeB. Grade N45
- Gauss Rating: 13,500 Gauss
- Pulling Force: 109 lbs
- Pole Orientation: Magnetized through the thickness, the poles are on the 4" x 1" surfaces.
- Coating: Ni+Cu+Ni 3 layer coating, the best coating available.
- Tolerance: The tolerances of all the dimensions are +/-0.002in with coating.
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.
- If damaged please dispose of completely. Shards are still magnetized and if swallowed can inflict serious damage if magnets join inside the digestive tract.
Warranty
This magnet includes a 10-year warranty for its magnetic strength, provided it is used under normal conditions. Usage in environments with elevated temperatures, significant vibration, or intense opposing magnetic fields will render this warranty null and void. It is also not suitable for use outdoors or in areas with high humidity or salt content, unless additional protective insulation measures are implemented.Product Videos

N45 4 x1x1/2 inch magnet
Arrived quickly, well protected against shipping damage. I made a sled out of thin acrylic sheet bent so I had a good hand hold and tapered the edge down to prevent the magnet slamming down as I removed it when putting the magnets onto 1/2 in steel plates. I really appreciated the marking of the N side of the magnet as the array I was making required them to be alternated with each other.

Great Magnet
Great finish, no issues with quality, best prices I've found, ships in steel insulated box, very strong
