FMF-40 Compact Levitation Cold Crucible Vacuum Melting Furnace


FMF-40 is an Advanced Vacuum Float-Melting System for exploring new generation magnetic alloy and metallic materials. The system uses 40KW high frequency induction heater to cause metallic sample to float during melting by magnetic vortex within a special designed water-cold copper crucible placed inside a vacuum sealed quartz tube. Therefore, it can produce extra high purity ferro or magnetic alloy without any contamination.
