Steel protects the magnet from damage,lasting longer than a standard magnet. Neodymium magnets are usually coated -Copper- plating to prevent the iron from rusting. Neodymium (chemical symbol Nd) is 60 on the periodic table. It is a earth metal and forms one of the Lanthanides series. When added to Iron (Fe) and Boron (B) (chemical formula Nd14Fe21B) the resultant magnets are the strongest magnets currently available. Circular Disc Magnets are made from Neodymium Magnet material and have unbelievable magnetic performances. Top quality with good quality coating.
