Susceptor heating is a poplular induction heating process. A susceptor is a conductive metal material that is used to transfer heat to another piece of metal or non-conductive material. Susceptors are often made from graphite because it is highly resistive and very machinable, or alternatively from stainless steel, aluminum, or other materials.
Heating An Inconel Susceptor for a Jet Fan Blade: 1 minute, 1950°F
Heating A Graphite Susceptor Boat: 7 minutes, 1200°F
