TVM are vacuum induction melting furnaces designed for the melting of titanium, TiAl, nickel-based super alloys, stainless steel, cobalt, neodimium and more exotic alloys under vacuum conditions using electromagnetic induction as the energy source for melting the metal. The source of induction is a water-cooled copper coil which carries an alternating current. The eddy currents heat the charge to melt.
