General introduction of cast AlNiCo magnets (aluminium-nickel-cobalt)

Using patterns and simple moulding techniques, cast AlNiCo magnets can be cast to form a vast range of complex shapes and sizes at an economical cost. Eclipse Magnetics AlNiCo magnets are ideal for high temperature applications up to 550ºC. Cast AlNiCo magnets is very stable, has good corrosion resistance and a typical hardness of 50 Rockwell C. Once cast, the material is so hard that the only machining possible is grinding. Cast AlNiCo magnets represents the most versatile magnet material available. The range of properties can be accurately designed for specific applications by changes to element analysis and heat treatment.

We know the professional manufacturers and suppliers of cast AlNiCo magnets in China.

Typical applications of cast AlNiCo magnets:

  • ABS braking system magnets
  • ABS braking system magnets
  • reed switch operating magnets
  • electricity meter damping magnets
  • holding/clamping applications
  • microwave applications
  • weighing scale damping magnets
  • electropermanent systems
  • calibration magnets
  • heat treatment jigs and fixtures
