Aluminum Heat Treatment

Aluminum Heat Treatment/Aging Process

Aluminum Alloy Heat Treatment Services

The aluminum alloy heat treatment process increases the hardness and strength of a specific set of aluminum alloys. Pentz Cast Solutions has the expertise and capabilities necessary to heat treat aluminum alloy castings to meet your application requirements. We have experience working with a wide range of aluminum, including 535 Aluminum Alloys, A356 alloys and more. All our treated aluminum castings are rotary degassed and flux injected to assure extremely low oxides and hydrogen porosity in all molten metal prior to creating castings. Our heat treatment process can increase integrity, elongation, corrosion resistance and more depending on your needs.

Please Contact us online and let us find the right aluminum grade for your next project or Request a Quote and let us get started treating aluminum to your specifications.

Pentz’ Aluminum Heat Treatment/Aging Process

Pentz quality starts with procuring USA-produced pure primary alloys to build high strength high integrity castings. We then collaborate directly with customers to determine which alloy selection and heat treatments are best suited for your project to achieve high performance, high quality and manufacturability. All Aluminum Alloy Metals at Pentz are then rotary degassed and flux injected to assure extremely low oxides and hydrogen porosity in all molten metal. Alloys are then tested using specific gravity to measure quality standards are met and recorded before pouring all customer castings. An-house Spectro-chemical analysis is used to confirm that the chemistry of all alloys meets the strictest customer requirements. Our process control and quality control is performed with in-house NDT Philips Real-Time X-Ray and Test Bars.

Benefits of Heat Treatment Processes

Heat treated aluminum offers several unique benefits not found in standard aluminum, with factors such as stability, elongation and integrity all varying depending on the grade to which the aluminum casting is treated. Some benefits of heat treated aluminum compared to standard aluminum are:

  • Increased Machinability
  • High Thermal Conductivity
  • Added Corrosion Resistance
  • Improved Surface Finish & Anodized Appearance
  • More Lightweight & Energy Efficient

Aluminum Alloy Heat Treatment For Multiple Industries

We have experience heat treating aluminum for a variety of applications and are always ready to fill low and high-volume casting orders. Some frequent industries served include:

Pentz’ Aluminum alloy metals are rotary degassed and flux injected, and all alloys are analyzed by our in-house Spectro chemical analysis for ensured performance and quality. We will collaborate directly with you to determine which alloy selection and heat treatments are best suited for your project needs.

Popular Heat Treated Aluminum Alloys

Pentz can procure a wide range of Aluminum Alloys castings for customer projects and production upon request, including:

We heat treat your castings and can water or air quence to meet your mechanical property requirements by adjusting our heat treat specifications. For our full selection of available alloys, please see our Aluminum Alloy Selection Guide.

Aluminum 535 Heat Treatment Considerations

When producing 535 Aluminum Alloys castings of high quality, integrity, 10% elongation, no heat treatment is required as it is self-aging and dimensionally stable. Taking 535 alloys to further increase dimensional stability is accomplished taking 535 alloy to T5 and cooling in still air for high-performance castings as customer applications require.

Additional Heat Treatment Resources

Heat Treat Designations / Descriptions

  • F:    As cast
  • O:   Annealed
  • T4:  Solution heat treated and naturally aged to a stable condition
  • T5:  Cooled from an elevated temperature shaping process then artificially aged
  • T6:  Solution heat treated then artificially aged
  • T7:  Solution heat treated and overaged

Heat Treat Definitions

Annealing:  Heating castings to increase ductility, which allows for straightening before heat treat   
Solution Heat Treat:  Heating castings to a suitably elevated temperature and holding at that temperature long enough to allow elements to enter into a solid solution and then cooling rapidly to maintain that solid solution.   
Aging:  Precipitation of solute atoms at room temperature (natural age) or elevated temperatures (artificial age).   
Overage: Additional aging to improve dimensional stability.
