VACUUM INDUCTION MELTING

VAC was the first company worldwide to successfully process melting and casting under vacuum conditions on an industrial scale to get Ni, Fe, Co and Cr alloys with lowest levels of C, N, O and H as well as lowest levels of non metallic inclusions (oxides, nitrides, carbides).

Inductive heating yields excellent homogenization of composition and of temperature. The purification process is enhanced by additional Ar-purging of the melt.

The high purity and homogeneity associated with as narrow as possible tolerances for chemical composition are fundamental for the production of alloys with superior soft magnetic or other unique physical properties as well as for the production of highest grade Rare Earth permanent magnets.
