Vacuum induction melting is a process for melting metal under vacuum conditions using electromagnetic induction. It works by creating electrical eddy currents in the metal which heats the "charge" to melt it. This process is used for refining of high purity metal and alloys, among other things.
The process was developed for specialised and exotic metals, however as the use of these metals and alloys increases, vacuum induction melting is becoming more commonly used. Some examples of its use include aircraft engine components and stainless steel for nuclear applications.
