Title:

Wide Metallic Glass Ribbon Processing Unit

Value Proposition:

Production of different types of alloy using melt spinning system

Summary Application:

It has a  wide application in rapidly solidified material processing unit for magnetic alloys that can be used in transformer core, magnetic sensor applications, saturable reactors, choke coils, core materials for circuit breaker, etc. and also processing unit for brazing alloys  that can be used in joining materials as heat-exchanger for automobile and aircraft industries.

Advantages:
  • The liquid metal is poured on water cooled Cu-wheel which can rotate at a speed of 1000 -3000 rpm.The system can be   operated in normal and controlled atmospheres.
  • The type of alloys that can be prepared through this melt-spinning system are
  • Glassy magnetic alloys: Fe-Si-B, Fe-Ni-B, Co-Si-B
  • Nanostructured magnetic alloys: Fe-Nb-Cu-Si-B,Fe-Co-Nb-Si-B
  • Brazing alloys: Cu-Ni-Mn, Ni-Fe-Cr-B-Si
  • No hazardous gas emitted
  • Ferromagnetic shape memory alloy: Ni-Mn-Ga, Co-Ni-AI
