This powerful neodymium block magnet measures 1/4" in length 1/4" in width and 3/8" in thickness and is made of a grade N50 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 has innumerable uses as a holding magnet, but is also great for an assortment of both industrial and personal applications and can be used in an almost unlimited amount of ways.

Please note that all neodymium magnets are fragile and require extreme caution when handling due to their brittle nature and to avoid accidental pinching.

  • Material: Sintered NdFeB. Grade N50
  • Gauss Rating: 14,400 Gauss
  • Pulling Force: 10 lbs
  • Pole Orientation: Through the thickness, the poles are on the 1/4" by 1/4" sides.
  • Coating: Nickel-Copper-Nickel triple-layer, the best 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.

  • small and powerful

    by Roy Dubs – 12th Feb 2013

    I use small powerful magnets in many ways. I keep them in my pocket and they help identify brass, stainless steel and other non ferrous metals. I use them as a teaching tool with kids (and grown ups)
