Drop Bottom Aluminum Heat Treat Furnace

Drop-bottom aluminum heat treat furnaces are used to solution heat treat aluminum alloys.  ITS Drop Bottom Furnaces are designed to operate with tight uniformities from 300°F to 1200°F for maximum flexibility to allow for aging and annealing. ITS specializes in large volume workspaces with standard lengths to 40’ and heavy loads with standard sizes to 20,000 lbs.

Aluminum solution heat treatment is the heating of an alloy to a suitable temperature, holding it at that temperature long enough to cause one or more constituents to enter into a solid solution and then cooling it rapidly enough to hold these constituents in solution. This is often followed by a precipitation-hardening process to increase the yield strength of the alloy.

Tight Tolerance Aluminum Furnace Systems

Maintaining tight tolerances is critical for Aluminum Heat Treating applications.

Tight Tolerance Heat Treat Furnace


Drop Bottom Aluminum Heat Treat Furnaces with quench meet AMS, BAC, and client specifications.

Drop-bottom aluminum heat treat furnaces are used to solution heat treat aluminum alloys. The furnaces are typically used when very fast water quench times are required. The furnaces are designed to meet all requirements of Aerospace Material Specifications (AMS) and Boeing Aircraft (BAC) specifications. The quenching solutions can include water, glycol, oil, or air. Because of the height of these systems, they are typically installed in a pit. The quench tank and load/unload station is typically mounted on a moveable cart underneath the furnace. Rinse stations for glycol quenching are available as well.

Lighter, stronger and faster, aircraft and automobiles means today’s heat-treat furnaces must be more uniform, flexible and energy-efficient to deliver required results for customers. Learn more about maintaining tight tolerances on the drop bottom aluminum furnaces.
