Heat-treating is a process by which various properties of metals may be changed by heating to a specified temperature, holding at that temperature for a set amount of time, and cooling at a prescribed rate.  A wide variety of methods can be used for heat treat processing.  

Furnace Brazing gives the ability to join metal components using a braze filler metal with a lower melting point than the adjoining components.  Brazing allows joining both similar and dissimilar metals with a significant amount of strength.  

Along with the one of the more common heat-treating methods, air recirculating ovens, ETI INC. houses more specialized equipment like inert gas atmosphere and vacuum furnaces which can be used for both heat-treating and brazing.  The inert gas atmosphere and vacuum furnaces produce repeatable high-quality results.
