Solution Heat Treatment is a treatment in which an aluminum alloy is heated to a suitable temperature and held at this temperature for a sufficient length of time to allow a desired constituent to enter into the solid solution, followed by rapid cooling to hold the constituent in the solution.
A time-temperature-dependent change in the properties of certain aluminum alloys. It is the result of precipitation from a solid solution of one or more compounds whose solubility decreases with decreasing temperature. For each alloy susceptible to aging, there is a unique range of time-temperature combinations to which it will respond.

Q: What metals or alloys can you heat treat?
We specialize in heat treatment of aluminum only. Metals such as steel or titanium can also be heat treated, but require temperatures that are outside our current qualified oven operating range.
Q: Do you recommend processing to a specification? What are the risks of not processing to a specification?
Many purchase orders will call out a processing specification. This will get you a certification for both a desired result, and a promise that the process was done within set parameters. The main disadvantage to spec or certified work is the cost. Alternatively, purchase orders may call out a result only. This can provide a major cost savings. Plus, customers get the benefit of having their work done with the same certified equipment, by the same certified operators. However, the product cannot be certified to a given specification.
Q: Can you process to specifications not listed above?
The specifications listed detail our current operating capabilities. Specifications such as AMS 2770 and other steel heat treatment specifications can be met, but may require a significant investment.
Q: How large of a part can I have heat treated?
See our size capabilities chart. Our ovens are regularly tested for uniformity within the sizes shown on the capabilities chart. If you have a uniquely shaped product, please contact customer service to discuss specifics.
Q: What turnaround time can I expect?
We pride ourselves on rapid turnaround. Our rates can fluctuate depending on demand, but we typically finish parts within a week, and often sooner. Heat treatment by nature can be time intensive however, depending on the aging process. You many need to plan schedules accordingly.
