Item Description:
Neodymium (chemical symbol Nd) is element 60 on the periodic table.
It is a rare 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. Neodymium magnets are sometimes known as Neo,
Neod or NIB magnets.
Neodymium magnets are usually coated Nickel-Copper-Nickel plating to prevent the iron from rusting.
Neodymium block magnet was made of NdFeB, have strong magnetic performances
and appearance does not rust, usually placed in room temperature, the maximum operating temperature is 80 ° C ,
and it never will demagnetization.
Please be care when break apart because Neodymium block magnet have strong Magnetism.
