n38 neodymium magnets widely used in teaching and playing.
Description:
1) The magnetic properties of rare earth magnet are very stable in change of temperature (-0.02% / °C for Br)2) Magnetic properties of rare earth magnet are steady in prolonged use 3) The uniformity for magnetic properties is excellent 4) Because of the high coercive force, the demagnetization to external magnetic fieldis very small
Cast AlNiCo Cast alnico magnets, which are aluminum nickel-cobalt-iron alloys, are the most established and widely used permanent magnet materials. Because of their high fluxdensity and superior temperature stability, cast magnets have been accepted inthe widest range of application.
Application:Speaker: telephone mobile odometer eletricitymeterWatermeter: eletricity motor switch adhesion sensors
Sintered AlNiCo In comparison with other permanent magnet materials, the sintered alnico magnet products are characterized by: 1. Fine crystalline metallic structure 2. Very high temperature stability 3. Good corrosion resistance 4. High mechanical strength
