This small rectangular magnet is made of grade N45 NdFeB magnetic material. It's magnetized through 1/8" so the poles are on the 1/2"X1/2" surfaces. The magnet is made to the tolerance of +/-0.01mm including the coating layer. The triple layer Ni+Cu+Ni coating is the best coating technology available. Based on the size and the grade, the pulling force of this neodymium magnet is 6.9 lbs!

About Neodymium Magnets:
About CMS Neodymium Magnets: With the state of the art technology, CMS Magnetics makes top notch neodymium magnets concerning the magnetic strength, stability, tolerance and the coating quality. CMS can make up to N53 grade neodymium magnets and the largest dimension can reach more than 8 inches. Neodymium magnets are also known as NdFeB magnets, or neo rare earth magnets. Since it is 8 more time stronger than the ceramic magnets, it's also called super strong magnets or super powerful magnets. The major elements of this magnet include neodymium (Nd), iron (Fe) and boron (B), or NdFeB.
