Molycorp Tolleson utilizes vacuum induction melting (VIM) to produce a wide variety of complex custom-made alloys. VIM technology is most suitable for the production of specialty and exotic alloys, since these alloys generally contain a mixture of reactive and refractory metals which necessitate the utilization of inert atmospheres, high melting temperatures, stirring and homogenization.
By utilizing proprietary VIM operating techniques developed over the past 30 years, Molycorp Tolleson is able to remove volatile trace elements (i.e., selenium, antimony, tellurium, etc.), keep oxygen, nitrogen, and hydrogen levels extremely low, and produce very homogenous and precise alloy products.
In the production of all specialty alloys, Molycorp Tolleson believes that it is extremely important to work very closely with customers so that it produces alloy products that meet all of the customer's physical and compositional requirements.
