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) this forms very strong magnets.
Neodymium magnets are coated in Nickel-Copper/Nickel plating to prevent the iron from rusting. Neodymium disc/block magnets are made of NdFeB, have a strong magnetic performance and will not rust.
Usually placed in room temperature, the maximum operating temperature is 80 ° C.
Tips:
1, Strong magnets should be kept away from products, such as monitors, bank cards, computers, televisions, mobile phones and similar.
2, Strong magnets should be stored in a dry, warm environment. Please Note: When connecting two magnets, draw them close to each other slowly and gently. Hard impacts can cause damage and cracks in the magnetic material.
