This powerful neodymium brick magnet measures 1/2" in length, 1/4" in width, and 1/4" in 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 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 rare earth magnets are fragile and require extreme caution when handling due to their brittle nature and to avoid injury due to pinching.

  • Worth the wait. Matches specs.

    by Byron – 1st Feb 2013

    An important factor for me is the accuracy of the specifications. In this case I laser cut parts in advance of receiving my magnets and they ended up fitting perfectly. I didn't check with a caliper, but the dimensions were clearly very accurate and consistent. As you would expect with an N45 rating, these are very strong magnets. Be careful not to pinch your fingers between them! My only complaint is that the shipping could be a little faster. I ordered several other items from other companies located similarly far away in the same day with the same shipping and my magnets took several additional days to arrive. That said, I have ordered from this company before and will continue to do so in the future because they provide quality products at competitive prices.
