These neodymium magnets are made of grade N42 high quality neodymium iron boron magnetic material. The dimension of the magnet is 3/8 inch (0.375) diameter and 3/8 inch (0.375) long with the N and S poles on the flat surfaces. Thsese neodymium magnets are coated with nickel-copper-nickel for a shiny corrosion resistant finish. The individual pulling force is approximately 14.0 lbs. The tolerance of the dimensions is +/- 0.01mm.

CMS Neodymium magnets are the strongest permanent magnet currently made with the top quality neodymium, iron and boron. They are amazingly powerful for their size and have innumerable uses.

CMS makes the top notch neodymium magnets with the state of the art technology. CMS neodymium magnets are superior to other brands in terms of higher strength, better coating, tighter tolerance and better longevity. All the CMS neodymium magnets are made under ISO 9002 quality systems. Please read the instructions before use the magnets.
