AL-NI-CO magnets is mainly composed of aluminium,nickel an cobalt.Because of its excellent temperature stability,good resisitance to demagnetizition from vibration and shock,high residual density and magnetic stability.AL-NI-CO magnets is accepted in wide range of application,like generator,lifting,microphone, voltmeters and measuring instruments. Sintered Samarium Cobalt Magnets,available the designer a tremendous combination of extremely high magnetic properties,outstanding thermal stability and excellent corrosion resistance.These characters make smco the ideal material in applications like servo-motor,pump couplings,and sensors,particularly where the magnets is required to operate at high temperature,accross abroad temperature range of in a corrosive environment.
