Product information "NdFeB Disc Magnets, Dimensions: Ø 6 x L (various lengths), Material grade: N38"
Rare earth permanent magnet NdFeB is a new kind of magnetic material developed in the 1980's with excellent magnetic characteristics (high energy product and high coercive force etc.) and relatively low cost. It is getting to replace the traditional magnets of hard ferrite, AlNiCo and SmCo in many fields such as electro-acoustic devices, electric motors, sensors/transducers, instruments and meters, auto industry, petro-chemical industry and magnetic health-care products etc.
Produced by powder metallurgical method with chemical composition of Nd2Fe14B
High resistance to demagnetization
High magnetic values (Br, bHc, iHC und (BH)max)
Excellent cost to performance ratio
Reasonable temperature stability
Very brittle & hard
Poorest corrosion resistance of all commercial magnetic materials
Not suitable for application which exposed in high temperature conditions
Ø 6 x 2, Ø 6 x 4, Ø 6 x 5, Ø 6 x 10, Ø 6 x 20, Ø 6 x 30
