1.introduction of ndfeb magnet 
Sintered NdFeB Magnet is one of the high performance rare earth permanent magnets, which use neodymium (ND), iron (Fe), and boron (B) as their main ingredients and is susceptible to be demagnetized when exposed to increasing temperatures. By adding some necessary rare earth elements, neodymium magnets can withstand higher temperatures varying from 80~220 Celsius degree. Neodymium magnets are classified into different grade like N, M,H, SH, UH, EH, AH,ETC by magnetic energy and temperature resistance ability. Pls See attached Magnetic property lists.

5. Warning on using safely
1)Strong magnets should Keep away from Ironware and some easily magnetized iron products,such as monitors, bank cards, computers, televisions, mobile phones and other.
2)Strong magnets should be stored in a dry, heated environment, and need to use of plastic,wood, cardboard, foam to separated and wrapped.
3)Magnets might be interested in water meter ,Electric meter, gas meter and some metering equipment exist some inaccurate affect (Such as : if magnets placed near the meter, the meter will slow down)
