Features Of NdFeB Magnet               

Neodymium magnets are currently the most powerful magnets known to man. They have a strength which is around 10 times stronger than ceramic magnets. You can use a much smaller neodymium magnet in place of any other type and the holding force will be equal if not greater!!

Do not heat these magnets above 80 degrees C (175 F) or they will begin to lose there magnetic properties.

The curie temperature of these magnets is 310 degrees C - this is the point at which the magnets will totally lose their magnetic properties.

Neodymium magnets are also known as NdFeB or NIB magnets because of their chemical composition - Neodymium, Iron & Boron. They are also commonly referred to as Neodymium or Neo magnets.

-----High remanence (Br) and energy product (BHmax), the strongest type of permanent magnet

----- High coercivity (Hci), high resistance to demagnetization

------High mechanical strength,easily to be processed to many shapes

------Lower Curie Temperature,not suitable in high temperature but stable in ambient temperature

------Low anti-corrosion,need surface treatment
