Minimum Order Quantity (MOQ) = 10 pcs

Common Applications:  Motors, generators, pumps, sensors, and holding applications

About Mid-Sized Rectangle Magnets:  Defined with a length between 0.251” (6.375mm) - 0.999" (25.375mm).  The surface area will determine the reach and profile of the magnetic field and performance of the rectangle magnets. 

Direction of Magnetization (DOM):  Rectangle Magnets are manufactured so the DOM is set during the manufacturing process and cannot be changed.  Available options during manufacturing for DOM:

  1. Through the length
  2. Through the width
  3. Through the thickness

Magnetic Grades:  To view a table of grades and specs, see our Neodymium Magnet Grades & Specs

About Nickel Coating on Magnets:

  • Most common coating on magnets
  • Actually 3 layers, nickel-copper-nickel
  • Protection of the magnet from corrosion in ambient air
  • Not a protective coating from humidity, water, or salt water
  • Light protection of the magnet from chipping
  • A decorative finish
  • Shiny metallic gray finish
  • Thickness: 12-25 microns
  • Cost: Low
  • Max working Temp: Approximately 200oC
