how is nitinol created

  • Vacuum Arc Remelting: This is done by striking an electrical arc between the raw material and a water-cooled copper strike plate. Melting is done in a high vacuum, and the mold itself is water-cooled copper, so no carbon is introduced during melting.
  • Vacuum Induction Melting: This is done by using alternating magnetic fields to heat the raw materials in a crucible (generally carbon). This is also done in a high vacuum, but carbon is introduced during the process.
